Re: [osg-users] OSG BOF at SIGGRAPH 2019 in Los Angeles
Greetings John! I will be there! I didn't have anything to present this year. I've been digging myself out of the Ridgecrest Earthquake so I can get back to work. I will bring my AV gear that you need. If anyone has an issue messing around with the ".earth" files for OSGEarth I could give a brief guidance on that - given that I've been messing around on that stuff for a spell now! ... Thank you!

[osg-users] Osing OpenXR in OSG
Greetings! I guess that I'm going to gripe on this subject like I did a year ago! I know that OpenXR is at least in Open Bata and I was wondering what progress anyone has made incorporating it in OSG. While I was in GDC I did see Khronos make some progress in this area and I even got to see someone do a demo of a VR display using HTC Vive. I challenged the group that worked on that and never heard from them again. I think one of the holdbacks was the interactive controls was not set yet, but from my perspective, they could have worked at the visual. I know that if I had the time and resources that I would hack this out, but one of the sad drawbacks of having a job is not having the time. It must be that most people still see this technology as a flash in the pan, but I think it’s taking on traction. ... Thank you! David Glenn.

[osg-users] So what is the status of VR camera to be used in OSG in 2018?
So what is the status of VR camera to be used in OSG in 2018? I know that Khonos has the OpenXR project that as far as I know is taking over the OpenVR idea. I don't think anything has been established in terms of a SDK for it yet, but I could be wong! The way I see it: it would be a self motivated double camera for a start. Add the controlers after that for ancer points for hands + plus a call back for contol actions later. For somthing like OSG, you what to keep it low level and simple for maximum flexibility. So, does anyone got anything like that I can Play with and make some proof of concept demo? Time to shine!

The internal accelerometer seems to work well enough for me so I've just been using that alone for now. They have a Unity plug-in and it has it's own version of the server that I've been using. I have made some Unity test Demos using that and it has been working well. I'm going to whip up some simulation demo and attach OSVR (and later Oculus Rift) to it. Maybe John will let me demo it at one of his BOF's at Siggraph this year. I may give a pretention at one of the fan cons - like at Dragon Con. I'm almost putting the PowerPoint presentation together as I speak. Using this stuff, I'm reminded of the tracking stuff that I used to do when was working in immersive simulation. Especially the tracking! I used to use that tracking hardware that InterSense made long ago!

Re: [osg-users] Anyone Experimenting with OSVR
Greetings All! Got my OSVR HDKv1.3 last week! I had to wait till the weekend to really try it out and there are still parts of it that I have not tried out yet (like the IR camera). So far most of the effort has been testing what works and what is a work in progress. One thing that I noticed off the bat is that the screen is only at an HD level. Also, I'm evaluating it using game development software. So I'm going off the deep end right out of the box. I feel comfortable doing this given that I have already been dabbling in Oculus Rift from the start, so I can compare and contrast. So far, I have dealt with Dev Kit 1 and have dabbled with DK2 and other demos and this is just another notch in the belt for me, but most of this has been done using Unity because it more geared to what my handlers expect me to develop to theses days. However, I am always looking at subjects that I can learn and give talks about and I'm getting a little sick of talking terrain. VR has a little more meat on bones and it would be nice to get something working in VR for the next SIGGRAPH BOF.

Re: [osg-users] Anyone Experimenting with OSVR
Greetings All! I've been messing with Rift at work for some time now but mostly on Unity, so I wanted to get a feel of how others are out there and I did get a taste of OSVR at the razor booth at GDC. So when it came to getting one for my own experimentation, I decided to try the HDK out! I Figure that it might not be at the level of Crescent Bay, but it can't be any worse than DK1. That's about the level that I've been able to study at in given that I'm not a AAA game developer.

Re: [osg-users] OSG BOF at SIGGRAPH was a SUCCESS
Greetings! If you what, I have three YouTube videos: One is the Boston Demo that Pelican Mapping did: its only a demonstration of the boston.earth file to show off what osgEarth can do! Later, I would like to do a breakdown of what is being displayed and how to do it, but that is for another talk down the road or anther video. Boston Demo https://youtu.be/Z_7afNznnRs Next is one that I made up from two examples that is part of the test set of xml files provided in the source. It shows nexrad data on top of Open Street Map. Nexrad on OSM https://youtu.be/ctdNF5wHpMk BTW: If anyone out there has used wms data other than the source example I used, please let me know, I'm trying to find other weather radar sources to try out and I'm by no means an expert of this stuff. Finally I did a mixture of something old and something new. I mixed some of the data that I used to make the Virtual Planet Builder map and mixed it in with Open Street Map. VPB data on OSM https://youtu.be/Mh7Yd6bh0BQ I also have other files from the Pelican Mapping that I will post as soon as I can get myself settled down from all this travel - I've been away from home for nearly two weeks. Sorry for any mistakes or misspellings I made. Hopefully the YouTube videos that I plan to make will cover all the questions that you just can't cover in a BOF.

Re: [osg-users] Thoughts on Vulkan
Well Chris, I don't think that anyone has ruled out using Vulkan on OSG, it just that the verdict is out about adoption. Besides, as I have learned from my resent VR experience, sometimes early adoption is not the wise course of action. As for me, I will adopt Vulkan when I have a good understanding of how it works and the standards are stable. It took awhile before the standards for GLSL to be ironed out. I'm worried about it being the same way for Vulkan.

Re: [osg-users] Uning Virtual Planet Builder in MS Windows!
Thanks for the pointers Arthur! At the moment I'm trying to bang some shape files into a wireframe of Europe and I'm using QGIS. I'm also looking at G-Dal functions directly. I know that there is got to be a way to make little geo-referenced tiff cubes because Europe is so darn large. Oh, I forgot that it has so many little countries in it - I got to take the time and visit them some day! Anyway, I thank you for the notes you gave me. I wasn't planning anything too technical for the VPB video at least for the first round. I'm waiting to get the viewer started on a basic level first. Then he might be inspired to research and learn the finer points of developing better maps later on. In video 2 I added annotations to allow viewers to skip over parts and to get to a section to study. Later on, if I get the time, I might add links to more advanced topics in a section of study, like G-Dal topics or more places to get data and the like. Right now, I'm tied up in Unity 5 and Oculus VR research. Oh, and just toss in SteamVR and OSVR on top of that as well while you at it. My plate runneth over right now! Anyway, I hope that the first video helps you! I didn't see any big problems other than getting the proper G-Dal build for the Visual Studio C++ compiler and was also compatible with some of the other tools I use like Open Flight Creator that also uses G-Dal and will crash if you get versions mixed up! Also, in the version of C++ that I used there is a problem in the linker when you compile the VPB.DLL that I experienced in VS2010 and VS2012 and it was a Microsoft bug (or so I was told) and if it was, I am curious if they fixed it in later VS versions. Anyway that all that I can think of for the moment! Have Fun!! D Glenn kingarthur10 wrote: > Hello David, > > It's nice to see other people getting familiar with VPB.

[osg-users] Uning Virtual Planet Builder in MS Windows!
Greetings All, Sorry that I haven't posted I've been very busy lately! I've been meaning to post the location of the YouTube videos that I made based the presentation I gave at SIGGRAPH last year, but I've been stretched for time with my added duties working on some Unity 5 stuff. I don't remember if I posted the links for you all and you may have found this stuff already, but just in case: The first video is basically how to compile Open Scene Graph in MS Windows using Visual Studio Express as well as compile Virtual Planet Builder. I try to go through the process step by step and it is long on time, but in the end you get a compiled version of Open Scene Graph and Virtual Planet Builder. For most of you, you can skip this part as it purely how to compile code, but I believe in showing how to do things from the ground up and so the reasoning for the first video. Here is the Link for video 1: https://youtu.be/b2fW9d590lk The second video is the meat and potatoes of how to use Virtual Planet Builder to build a basic terrain for your OSG Project. I go over a bit about G-Dal given that I use it to prepare my data at times. I also show how I use QGIS and point out some sources for data and how to put it all together. Here is the Link for video 2: https://youtu.be/gcDSQ0t1Fd8 In the end I built a nice 3D map of the Humble town of Hemet Ca. using data that I got from the USGS. If you what to post this stuff any ware your welcome to do so! As I said before: I'm sorry for getting this stuff to you so late. I'm also working on some training stuff for Unity 5 and I still thinking about doing something on some other OSG stuff. Maybe osgEarth! Hope to see you all later! Hope you all are doing well!

[osg-users] Probems with compiling osg3.2.0 in debug vs. release in Windows.
Greetings All! I know I have been working with Linux for a few years and maybe I've been away from Windows too long, and this may seem silly to some but here it goes! I've been moving some of my stuff to windows and everything ports over very well, thank you, but one thing that I had to test on two systems to verify! When I compile osg core libraries using VS2010 or VS2012, in debug mode, when I get to compiling the osgPlugins DLL's my Norton 360 kicks in and Quarantines some of my osgPlugins DLL's. Out of frustration, I told Norton about this but they give me the same line about it and I say "but I just compiled it, I've been playing with this code for years and there is nothing wrong with it", but thats another story for anothr fourm. Well, moving along! When I compile the same stuff in Release mode, it compiles o.k. and Norton doesn’t smash it! So, for now I'm working with core libraries that are compiled in release for now and I'm wondering what work around I'm missing to get the stuff to compile in Debug w/o setting off the False Alarm Bells on my system! ...

Greetings John! Right now I've been tied up with three projects I'm working on my off time from home, but one of them is a set of YouTube videos that show how to compile and use OSG and Virtual Planet Builder in Windows using VS2010 express. I'll have some sides for the videos that I can whip up for a presentation if you like! I'm currently tied up in a Unity Game Engine animation demo for A-Kon 25 in Dallas, but after that raps-up in early June, I will be working on the OSG YouTube stuff almost exclusively. ---- David Glenn --- D Glenn 3D Computer Graphics Entertainment. www.dglenn.com -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59523#59523 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [vpb] Windows and weird error messages
Greetings All! I just went through the same thing! It would be good to make note of it some ware in a readme about it! I had to search though the forum to figure it out and I'm not sure I like the fix, but I can't find any better idea to work around it, but it works. The only other advice I have is to make sure you preinstall G-Dal and test it before you compile Open Scene Graph and VPB to them. I used G-Dal 1.10.1 that has installs and prebuilt lib’s and include that worked well for me. I used Visual Studio 2010 Professional with Service Pack 1 added. The only other suggestion I have is to add a command line shell that you can use to run VPB properly. I hacked mine using the shell that I found on the G-Dal core install and modified it so it can see all the g-dal stuff. I learned by antialiasing Q-GIS that the best way to do OSG anything in Windows is to have all the lib and executables in a single directory and use it from there. I moved all the binary’s to a single directory starting with the OSG binary stuff I compiled plus the plug-ins and adding the VPB stuff on top of that! I make sure that I added that to my path environmental variable. I open up the vpb command line shell, cd to the directory that I what to build my stuff and let her rip!

I had to compile Qt 5.1.1 under open source and install it. I haven't had a chance to test it out but under Linux cmake is far happier when thing are in their proper place in “/usr/local/ QT5.1.1” than it is when you try to access libraries in a folder in your home directory. By default Qt likes you to compile to your home directory but I like it to be globally accessible and apparently cmake like that too. other than that, my first steps to building the osg Qt viewer under Qt 5.1 has not worked out too well in RH 6.2 (64bit). Qt 4.8.5 has been better, but I have yet to test some of the stuff I have, so the verdict is still out!

[osg-users] migration from 32 bit OSG 2.8.1 to OSG current 64 bit release on RHTE 6
Greetings All! Well, the hard work is over! I've tossed all remaining remnants of the old SGI based code and now my project is now a %100 OSG project!! Yey!! What I have resisted until now to do was to migrate to the current version of OSG and move to 64bit mode until I finished development. Now a required move to a 64bit RHTE 6 OS has made that a necessity and I'm thinking of moving to the newest stable release. I'm currently using 2.8.1 so I know there was a change in native OSG model formats and about Qt. My question is what problems should I expect along the way (if any) and what is the best version to move to? ... Thank you in advance!

I just learned about it this week so I got a copy to review. As far as I can tell, there are not many papers (if any) on this subject and VPB is a remarkable tool. It's nice to understand the Terrain Theory that the bases to how this works. I must admit that most of the other paging schemes that I had to deal with in the past did not go as far as this and did not do as well. Mostly because they where hacks using preexisting terrain elements that where clearly not made for paging. This makes much more sense to me.

Re: [osg-users] [vpb] Quesions about LOD in VPB
Greetings Robert! I've been remerging around the code on VPB and I noticed that there is no way to set the PagedLOD range mode to PIXEL_SIZE_ON_SCREEN and of course do the setRange calculations for that. Is there any reason why or was was not added (sice it's part of PagedLOD) or there just no call to do that? I needed to change that because the Display program that I'm working on uses the viewing area (a.k.a the zoom) rather than moving the camera closer the terrain. It worked out very well.

Re: [osg-users] [vpb] Quesions about LOD in VPB
Greetings All! I did some analytical research on the files that VPB makes and confirmed that the software builds a map to a LOD that is equal to the resolution of the texture being used and stops at that point. I also discovered that if add two different types of textures shay one that has 15 meters of resolution per pixel and another texture that has say 1 meter of resolution per pixel that it process all areas up to the point that the 15 meter data is exposed then continue on only the areas that only the 1 meter data is exposed. That’s very cool! :) The Question I have is the question that I know I'm going to get asked, is what the function that does this is?

Re: [osg-users] [vpb] Quesions about LOD in VPB
This is nice but what I'm using this for is something like a Google map. You see it from a high view and it you can close in on an area in the terrain. So I don't mind using the full range of level of detail. I was under the impression that you had to set the level of detail get the most detail from the data, but if VPB does that all the better for me. I would just like to understand this because I also have to explain how this works if anyone is going to have any confidence in the data it makes. That is why I'm doing the paper on it! The only other thing was that we had to make a tool that changed the range mode on the PagedLOD node from distance to Pixel Size on Screen. As far as I could tell there was no command setting for this in VPB. We also did a pruning tool that allows us to cut back LOD on all but a given areas of the terrain. The sole reason is there are some areas on the terrain that require higher levels of detail than others so we can prune all but these areas down to a lower detail. This cuts down on the massive size of the terrain that makes it difficult to transport to other systems. Basically if we don't use the prune tool, a chunk of terrain can take up about 58 gigs of hard drive disk space on an average. But after using the prune tool, the same terrain is shunk down to a disk footprint of only 8 Gigs without any real loss of data - given that the data that is pruned out is redundant. This makes the terrain more practical to distribute. It's a little pricy from a logistical standpoint to be handing out USB bricks when compared to handing out a double layered DVD.

Re: [osg-users] [vpb] Quesions about LOD in VPB
O.K. Then the -l command sets the limit of the LOD you can have and not how many LOD's your terrain is going to have! By default it maxes out at 30 and the only reason to use it is to limit the LOD's (and detail) of your terrain, Right?

When I make a terrain with -l set to 20, I get a bunch of files titled with the name, level of detail number, the X location in the grid and a Y location on the grid fallowed with "_subtile"! I figured that I would find at least 19 sets of files listed from L0 up to L19 or L20 but what I get is 12 sets listed from L0 to L11. Can anyone explain this to me? I'm in the middle of writing a paper on this and after reviewing code and files, I thought I knew what was going on, but now I'm confused!! :?

[osg-users] [vpb] Quesions about LOD in VPB
Greetings All! I'm just getting the time to do some real study on VPB and I had some questions about LOD and controlling it! First of all, I'm going to reverence a tool that I know “Terra Vista” for an example. If you don't know about this tool, I understand and try to explain in more detail. One of the tricks you can do in Terra Vista is that you can limit the amount of LOD's you can use in a given area over others. This allows you to build terrain that has higher level of detail in some areas (where it matters ) and allows other areas to max out at a lower level of detail. This in the end would make the terrain take up less space than of all of the terrain was at a high level of detail. I managed to get a group of satellite data at 1 meter resolution and it works fine, but it's taking up over 50 gigs of Hard disk space. I like to cut it back a bit so I can at lease maybe get it on a double layer DVD, if not , a blue ray disk. I figure that if I can cut back on the resolution in areas that I don’t need to be at 1 meter resolution, I can cut the size in whole of the terrain to something more manageable.

Right now we are stuck in OSG 2.8.1 because in the long development cycle we have here at or lab! We will move to the newest stable release after the end of this development cycle, or if it fills a requirement that we need bad enough to upgrade. So far, nether event has happened. I Know that John did visualy compare the code and he told me that it does address an issue that is current in the present OSG 3.0.1 as we know it, and that the exampe code should be compatable in most cases. However, becouse we are not current on or own development systems at this time, one of us will have to set up on another box for testing the code under the current stable OSG version. I can do this when we can devote the time and resorces to do so in the future. Oh! For what its worth, we test things using QT develoment GUI. It makes it much faster to build quick makefiles though I dont recall any QT stuff being used in this example. Also, we did not try this under Windows OS, I'm not sure of the behaver there! In fact, I'm not doing any Windows OS development with OSG at the moment!

// Suggested Revisions to osgText::Text class.
// John Markano 3/21/2012
//
// The code below includes suggested fixes for two problems in osgText::Text
// in the OpenSceneGraph 2.8.1 release:
// (1) Text in object coordinates may be rendered with the wrong size.
// If an application requests a font resolution that the font doesn't
// support, OpenSceneGraph uses the closest supported
// resolution. osgText::Text does not handle this situation properly.
// It uses the requested resolution in some calculations where the
// actual resolution is more appropriate.
// (2) Text in screen coordinates may not be scaled properly when a
// perspective projection is specified. In particular, the displayed text
// size may vary with the field of view when it should remain constant
// relative to the screen.
//
// A class TextImproved is defined below to correct these problems. This class
// inherits osgText::Text and replaces three virtual functions in the parent
// class:
// - computeLastCharacterOnLine (for the first issue above)
// - computeGlyphRepresentation (for the first issue above)
// - computePositions (for the second issue above)
//
// Each of these functions includes suggested changes to the original code.
// The original code is also left in place for comparison. The preprocessor
// variable USE_ORIGINAL_CODE can be set to a non-zero value to compile the
// original code instead of the improved code.
//
// An example program is also provided below to provide a before-and-after
// illustration of these changes. This example program splits the screen
// into four quadrants, where
// - The upper left quadrant contains black text generated by osgText::Text
// with screen coordinates specified. It changes size with the field of
// view, but its size should be fixed.
// - The upper right quadrant contains black text generated by the
// TextImproved class defined below. This text should, and does, appear
// with a constant height of around 100 pixels. (No reference scale is
// provided.)
// - The lower left quadrant contains red text generated by osgText::Text
// with object coordinates specified. It should be one unit tall, but
// its actual size varies depending on what the active font supports.
// In this example, it's less than half as tall as the requested size
// because the default font resolution of 32 is much higher than the
// supported (by DefaultFont) resolution of 12.
// - The lower right quadrant contains red text generated by the TextImproved
// class. It displays closer to the correct height of one unit.
//
// The example program allows the user to increase or decrease the field
// of view using keystrokes. Type '+' to increase the field of view, or '-'
// to decrease the field of view. The camera position is fixed, so this
// is the only available viewing parameter control.
//
// This code was developed and tested using Red Hat Enterprise Linux 5.5,
// Qt 4.5.2 and OpenSceneGraph 2.8.1.
//
// This fix uses an uppercase E to find the available font size. This is
// a kludge that is inappropriate for many fonts. A suggested
// improvement would be to add a function to osgText::Font (and the
// DefaultFont subclass) to return the supported font resolution that is
// closest to the requested resolution.

[osg-users] Text Class Sizing Issue!
Greetings! One of the issues that were brought up by my partner out here John Markano was that when the text is set to screen mode, the tendency is that the text stays static in zoom in and then it will reach a point that it will start to shrink. My understanding is that is not supposed to happen. He handed me a test program that uses the existing way to play text and a new way - that doesn’t have that problem. John has expressed to me that he would like me to share the code for this if you all like! I studied it over and it works for me! ...

Believe it or not my webpage at "dglenn.com" got its start and was hosted on the first web server at csusb.edu. It was known as “www.csusb.edu/dglenn” at the time. This came about when I got selected to be one of the lucky CS students ether install, co-manage or publish materal on the first web server on campus. This under the direction of Dr. Murphy who chared CS at the time. It was the first public webpage at that University campus and it was only meant to be a test for the server for a short time. However, I got to keep the result of my efforts on-line for two years before it was closed. By that time I gotten my own domain "dglenn.com" and I just copied my old stuff to there and moved on with my life. Oh, yea! The latest version of the webpage is under reconstruction right now as it’s been for nearly six months now. I guess it will be finished when I can – I’m so tied up with other stuff! However there still might be some remits of the original webpage from Cal State kicking around some ware in a neglected folder, I’m not sure where anymore! maybe some things are best left unfounded! :) David Glenn --- D Glenn 3D Computer Graphics & Media Systems. www.dglenn.com -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=46114#46114 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Well, I would look at it differently (like using slave cameras), but in this
case, have you tried dynamically linking the node?

Greetings!
Since your so lucky to try out one of NVidea Beta Drivers, have you ran this
across the NVidia test team first? Also, I didn't get what Graphics Card you
are using!
That is where I would go with this! OSG works on top of OpenGL other than that
it is doing nothing directly with the card.
If your using beta, I would look towards the fact that it may be still buggy!
Also, it has been my experience with NVidia that newer drivers in Linux, don't
necessary mean that it's an improvement. I have had to backtrack on drivers
even on my OpenGL code stuff because Nividia broke something in the process.
They are more concerned over a Windows driver than Linux I think!

Re: [osg-users] 3D models used in OSG ?
Greetings! The biggest issue that I have had with tools outside of Creator is Hierarchy! In simulation, you need to be able to control the model by using switching, level of detail, etc. I haven't seen that much in open source that addresses that issue! I'm not sure if they have addressed that in Blinder or have come up with some other way other than passing it through Creator or maybe Remo 3D to finish it! The only other way I can think of off hand is to convert a set or elements of a model to OSG format and hand jam a Hierarchy in a text editor. That is out of reach for most of the casual or intermediate modelers out there that I know of that has had exposure to Creator. ...

Re: [osg-users] Open Flight characteristic not reflected in the current OSG
Greetings Paul: I thought I was going to get a break, but I guess that there is no rest for the weary. Good news is that I have this guy that on-board that's on top of that. Turns out that what you did worked but if you looked at the object that I gave you, it's solid ( its suppose to be transparent) The transparency is set at a node that is labeled WATER that introduces the transparency to the face (Primary) color. So my partner (John Markano) looked at GeometryRecords.cpp around some ware after line 431 (OSG 3.0.1) or 331 (OSG 2.8.1) he added the line: Code: _PrimaryColor.a() = 1.0 - getTransparency(); Then he thought this would have unwanted side effects (even though I didn't see any) and adopted a change in the same file but at line 257 (OSG 3.0.1) or 157 (OSG 2.8.1) change the code: Code: colors->push_back(_PrimaryColor); to the line : Code: colors->push_back(osg::Vec4(_PrimaryColor.r(), (_PrimaryColor.g(), (_PrimaryColor.b(), 1.0 - getTransparency())); Both seem to work in my perspective, but I was wondering what you thought or you had a better idea! ...

[osg-users] Open Flight characteristic not reflected in the current OSG
Greetings All: Something I found that is interesting in Creator 3.4 (Open Flight) that is not reflected in OSG. In Creator Face Attributes, under the Drawing tab, If your set the Shade to Gouraud, you are shading at the vector level, hence you usually set the colors at the vector points. What I found interesting is that if you don't set a vector color (leave the index color set to -1), since it is undefended, in Creators view it defaults to the Face color (or Primary Color). This does not happen in the Open Flight plug-in in either 2.8.1 or the latest I've tested 3.0.1 . I know this is not a documented feature, but maybe we need to cover this in the Open Flight Plug-in anyway so we are computable to that standard. It would be better than trying to explain to some of these modelers why they have to brake old habits when from their perspective, it only happens on OSG. ... Thank you!

Re: [osg-users] ATI FirePro M8900
Greetings! I have to admit that I've seen issues with laptops, but not like this! I have a desktop at home with two Radon 5800 crossfired tougher and used my software on that without any problem, then take it to a Laptop with what I thought was a higher speed mobile graphics card only to have it come to a screeching halt. One of the things you have to look out for is that Laptops are built for power conservation and to not to be a Lap Heater. Both the Operating system and Video card driver are set from the factory in a conservation mode that you have to disable to get any performance from the darn thing! Oh, don't think, Oh I'll just put it in performance mode and think you’ll get buy. You may also have to remove some of the background software components that were installed for convince sake of a laptop – like that thingy that you use with your finger to log-in to your computer. You may have already thought of this, but I thought I'd bring it up anyway for those who haven’t. I've had too many people bang on my head because they can't get my software to run on their laptops and after looking into their system, finding all this hidden background crap that was holding things up. Oh, and Linux users, don't think that since you’re not using WinDozze that you out of the woods either. I've seen my share of crap on laptops using Linux as well.

Re: [osg-users] assignment of context ID in osgViewer::GraphicsWindowEnbedded
Greetings! A bit of correction on the code: After we declared the variable Exp: osg::ref_ptr< osg::osgViewer::GraphicsWindowEnbedded> _gw; _gw = new osgViewer::GraphicsWindowEnbedded(0,0,width,height); we should add: _gw->getState()->setContextI(osg::GraphicContext::createNewContextID()); Anyway, I'm still wondering if this is something to add or it should have been called be default (hence it’s a bug)!

[osg-users] assignment of context ID in osgViewer::GraphicsWindowEnbedded
Greetings, I was just wondering! My co worker just found out that if your going to set up and close a set if windows that uses "osgViewer::GraphicsWindowEnbedded" that you better make sure that it has a unique context ID in it or strage things start to happen with textures. after we decared the varible Exp: _gw = new osgViewer::GraphicsWindowEnbedded(0,0,width,height); we added: _gw->getState()->setContextID(someIntNumber++); and it fixed our problem. The thing I'm wondering is why I have to do this in the first place? I figured that you had this handeled in the osgViewer init code someware becose I've never seen anyting about this in any of the example code that I've seen so far! Maybe we have a bug? ...

I'm not adding any drawables or changing much of the OSG code at this point. At least not yet! Grin!

Re: [osg-users] Performace issue with nVidia 400 series
Greetings! Well, given what I've been told by NVIDIA, that there is a Quadro group that if you develop with that card series that they will be at my bacon call and there is the GForce Group that lives in the nether regions. Getting help for Quadro is easy since it built only by PNY and they work closely with them. Getting help for GForce is a pain as they refer you to the other companies that usually don't want to deal with you! Never mind the fact that I represent a navy lab that is buying 200 of their cards, you’re still a second class citizen to them. EVGA (for example), I tried to get help configuring there card for Linux Box and I got "you have to go and check your bios on your EVGA motherboard to fix the problem. I replied that I had a graphics card and not a motherboard and get the same response. I guess that this is the punishment that I get for not going with Quadro! ...

I have a line trail that I make as the object moves along the screen. The line is determined by the user but can have 100 to 200 points that make it up that can be many kilometers long. Every cycle I add a new length to the line and tale one away. I do this by adjusting the vertex array that I added to the geometry at the start. After I make the changes to that, I call the dirty bit to refresh that. I also have a color array that I have set to a color. I grab that array and reset the color for that array (at the 0 point where I first set it) and I call a dirty bit on that. I also do the same for the Normal array but I use a saved setting of the normal (the normal never gets changed) and I call a dirty bit on that. All this changes the position of the line and the line snakes happily along the path of the object. The problem was that the color had issues changing! If a changed the color to black( 0.0,0.0,0.0,1.0) or white (1.0,1.0,1.0,1.0) it’s OK, but if I do a gray (0.6,0.6,0.6,1.0) I would get a white. If a force the normal array to be a double and use something like (0.01f,0.01,1.0f) and the color is set to gray I would get that color.

Greeting All! It's been a spell! The staff here has run into an interesting problem!

Re: [osg-users] Interest in new releases of 2.8.x?
I'm a bit confused here! Was there supposed to be a 3.0 release at some time, or was that the development release? Whatever became of that? I’m still using 2.8.2 because of requirement placed on me by my client but I somehow got lost out on the deference’s between the release and the what has been in development in the past 6 months. I kind of figured that a stable version of that development code would be the new released code by now, why not? ...

If you have any success, It would be nice (if you can) to share it with us! At least I think, we are rather starved for Shader ideas here. Oh Yea, be careful to avoid any Stupid Shader Tricks! :) Laters! -- D Glenn D Glenn (a.k.a David Glenn) - Moving Heaven and Earth! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36742#36742 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
