Re: [osg-users] OSG question on asynchronous texture readback
Hi, I checked the osgscreencapture example (from 2.9.8). It seems to only work asynchronously if I use the --rgba flag (time for read pixels = 0.045694ms time for memcpy = 1.5924ms) which sets the pixel format to GL_BGRA. Any other combination and the read-back slows down quite significantly (time for read pixels = 8.7473ms time for memcpy = 1.2335ms). My case is slightly different since I am trying to read-back from a FBO float texture instead of the framebuffer directly. I tried using GL_RGBA32F_ARB as internal format, GL_BGRA as source format, and GL_FLOAT as source type, ping-ponging between 2 PBOs and textures, and doing the read-back in the first camera but without success...

Re: [osg-users] OSG question on asynchronous texture readback
Hi Guillaume, The async reading of PBO's is very sensitive to pixel formats, frustratingly so. I would recommend reading up on topic and trying experimenting as you have being doing. Hit the right combination of formats and usage and your get great performance, fall of this fast path supported by the driver and it suddenly becomes far slower. Robert.

[osg-users] dtEntity OSG entity system videos
Hi all, I just want to inform you all about my ongoing work with dtEntity, a game/simulation framework on top of OSG. I posted an announcement a few months back, but a lot has happened since then. Most importantly, dtEntity is no longer dependent on Delta3d (although integration is still possible). Video 1, JavaScript demos: http://www.youtube.com/watch?v=FBkcEfFb7ug Video 2, Qt editor in action: http://www.youtube.com/watch?v=TiyoaAayVMw Project homepage: http://code.google.com/p/dtentity/ Features: * Pure component system - functionality is shared by composition, not by inheritance. No data or functionality in game object, game object is an aggregation of components. * Entity system approach to storing components - components are stored by type, not by game object * Fully scriptable with Google V8 JavaScript * Integrates libRocket GUI and CEGUI * Publish-Subscribe message system * Many existing components: Mesh, animation, text label, camera, transform, sky box, ground clamper... * Plugin system for loading additional component libraries * XML map format, maps can be independently loaded and unloaded at runtime * Qt based map editor * A Qt property editor, property edit masks are configurable on a per-property basis in an xml file (for example: Vec4 Property 'color' in component of type TextureLabel? should be edited with a color picker) * Hierarchical composition of entities is possible - use attachment points to define where in scene graph an entity shows up. Example: Sky box entity has a component LayerAttachPoint? that other entities can choose to attach to. * Can be compiled to use Delta3D actors. This way, delta3d features like Cal3d animation, clouds rendering etc can be used. * Debug draw manager for quickly displaying debug geometry like lines, points, triangles * Prototypical PhysX bindings I would love it if other people found this useful and maybe joined my efforts to create a slim, flexible simulation infrastructure for OSG!

Re: [osg-users] 3D models used in OSG ?
Hello, Thank you so much for all these helpful advices. I really appreciate that. I already bought the e-book of Rui and started to look into it. I read also the book of Paul Martz. Great books. My concern is about the time required for the development of a VR application with OSG +VR Juggler (we are going to have a CAVE for neuroscience research) compared to high-level-based engines like Virtools or Vizard of WorldViz. I dont' know if you know both of them ? I am evaluating these software in order to decide which one(s) could fit for our needs. Thanks again, Maia John Richardson wrote: Hello, The real question is how do you import models from commercial and open source packages into OSG and support for animations, Others can chime in technically on this... Yes, it does take artistic talent. However, your email is from Université Laval. So you have a perfect solution. Collaborate with the art department. However, I will give a synopsis of my process. I am not an artist. 0) The first step is buying the Wang Rui book on OSG. 1) Acquire Blender. 2) Acquire one or more commercial systems with large numbers of example models with an acceptable reuse license. Note: If your university has various numbers of 3-D modeling and animation systems take their various and sundry examples and export to VRML or COLLADA. Then examine their other export formats [File -- Export or whatever menu item does the trick]. The best of the proprietary formats are 3DS, LWO, OBJ. Now, when I say best or talk about VRML / X3D / COLLADA, I am talking about the file interoperability problem. These comments are just my philosophical workaround. So, now you have a lot of scene components. Either arrange them in your modeler of choice [originally before export with an artist] or import the exported examples and arrange them [you don't need an artist since I can do this]. I suggest that you give them useful names and if possible, give them useful names at the nodes that you may be interested in accessing via OSG for your simulations. There is no more advice I can give at this point on naming. The Web3D people tried with the H-Anim standard and other profiles to X3D [See the Poser character animation system if the university has one]. The problem domain is huge and nobody seem to be able to make train loads of money on the solution so there is no satisfactory solution. 3) Turn your yourself or your programmer collaborators loose on the OSG coding for import and scene manipulation. The coders should know the process for compiling/downloading. You already know how to access this list for advice. Also, note that there are lots of contributors to this list that can code if you have funding available [Guay, Hanson, Martz, Cigar, Osfield,insert name I left out here,...]. If your goal involves students, then I suggest that you approach the issue from a architectural perspective. There are a lot of architectural programs in the USD 50-150 range that export to VRML and probably 3DS and OBJ/LWO/DXF. These can be acquired at almost every Apple Store for the Mac and every Best Buy or Fry's or whatever giant Canadian electronics superstore is in your area for the PC [and possibly for the Mac] [Punch!;TurboCAD;...]. A nice city block or representation of Université Laval would be a starting point. Then just see if you can get a traffic or pedestrian simulation completed. This strategy is like using the iPhone's Siri [or Google Voice] as opposed to Dragon Naturally Speaking. The learning curve is a little bit easier. But DO NOT FORGET BLENDER [relatively steep learning curve]. The students need a portfolio. John F.

[osg-users] Another Qt inconsistency???
I noticed the following static function: Code: osgQt::setViewer(m_viewer); It appears this is not available in any other non-Qt mode. Is this because osg has no timers available? A very odd thing to me follows: I have a #define that allows me to either use the setViewer() mentioned above or my own internal Qt timer. When I use my internal Qt timer, I have the paintEvent() run the copied code from setViewer(). However, the graphics window never shows when x,y in moveEvent() is 0,0. If I adjust either x or y so it is anything other than 0,0, the graphics window display (obviously with background data showing). When I call setViewer(), I do not adjust x,y in moveEvent() and it displays without any problem (even when it is at 0,0).
