Re: [osg-users] osgDB/FileUtils causes compiler errors when building my project

Hello Phoung (I hope this is you first name) First of all, your description is a bit vague. Is it a compiler error or a crash? I guess it is a compiler error. If your compiler points to an osg header file, the error is most probably in your code. Check if there are any missing semicolons

Re: [osg-users] post-rendering warping and off-axis projection

Hello Ruigang, Check the osgdistortion example. IIRC, the example uses a RTT-Camera and displays a subdivided (and properly distorted) mesh and maps the RTT-result on it. For the off-axis projection I think you can either set up the projection matrices on your own, or use the viewers

[osg-users] Uniform above Program

Hi, it seems that it is not possible to put an uniform to the stateset of the scene root (for example, light position) and to put Program at the bottom (say, at a stateset of a drawable). It seems to me that the Program and all its Uniforms must be put the same StateSet. This way, it works

Re: [osg-users] Uniform above Program

Hi, John it seems that it is not possible to put an uniform to the stateset of the scene root (for example, light position) and to put Program at the bottom (say, at a stateset of a drawable). It's just not true, and works for me all the time. Can you post minimal example that dont work?

Re: [osg-users] post-rendering warping and off-axis projection

Hi For glFrustum-like projection : osg::Camera::setProjectionMatrixAsFrustum(...), or you can create matrix with osg::Matrix::frustum(...) and use this Cheers 02.08.2012, 00:52, Ruigang Yang ruigangy...@hotmail.com: Hi, I am in the process of converting an OpenGL-based multi-channel program

Re: [osg-users] Animation of shared model

Hi Sergey, Thanks for your advice! Unfortunately I'm not sure if I completely understood your solution. Would you mind to help me a little bit further? Suppose I retrieved the model and the animation manager as follows: osg::ref_ptr osg::Node model = osgDB::readNodeFile(nathan.osg);

Re: [osg-users] cannot get floating-point multisampled FBOs

Hi Robert I wonder if this bug has been investigated further or even fixed. Do you have any news concerning this? I face the exact same problem. No AA / multisampling on floating point render targets... Cheers, Daniel -- Read this topic online here:

Re: [osg-users] Animation of shared model

Hi your transforms(with animation managers) contain original model, which itself have another animation manager, you should move it out so get original animation manager and keep it, while removing it from original model, then add copy of it to your transforms. If it dont work out well - try

Re: [osg-users] OSG application on Microsoft Surface table?

That's odd advice for them to recommend XNA and WPF - XNA is a dead end; Microsoft has stopped supporting it. They no longer support any managed interface to DirectX; their new thing is XAML which pretty much limits you to 2D. As you can imagine, the Windows game development community - or at

[osg-users] [osgPlugins] osgShadow LiSPSM culling problem

Hi, I'm working with the osgShadow LiSPSM implementation as that seems to be the one that people have had the most success with. The shadows are great, but are being clipped vertically as the shadowing object moves near the left or right edge of the window. I've seen similar issues in other

Re: [osg-users] Uniform above Program

Hi Sergey, this never worked for me for about a half of year. Update: now it works! It seems that maybe, I was unlucky on svn update and, kept the update for a while, seeing this issue. Based on your assurance, I made some tests and updated my shader routines. All shows that the issue is gone.

[osg-users] ETC1 Compressed textures

Hi All So I've written an app for iOS that uses pvrtc format for a couple of big glyphmap textures 2048x2048. This works fine with the pvr plugin. I'm now porting to Android and have stubbled across the problem of not all devices supporting pvrtc. However supposedly all of them support etc1

Bit more info, I also used the 'Fast Perceptual' encoding method, if that is of any relevance. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49308#49308 ___ osg-users mailing list

Re: [osg-users] Animation of shared model

Hi Sergey, I removed the animation manager from the original model: model-removeUpdateCallback(model-getUpdateCallback()); and created a new animation manager with clones of the original animations: osg::ref_ptr osgAnimation::BasicAnimationManager manager = new

Re: [osg-users] post-rendering warping and off-axis projection

Thank you all for the quick reply. I also studied quite bit recently. The RTT camera is exactly what I need. In the OSG cookbook, there is a powerwall exsample. The use of slave-camea can make off-axis projection easier to set. Thank you! Cheers, Mark -- Read this topic

Re: [osg-users] Animation of shared model

Hi I checked osgAnimation sources, and it looks like what you want can be done that easy. Animation calculation happens in update traversal, and directly changes RigGeometry vertex data, so with shared rig geometry all instances will look same. So i believe you need at least to create

Re: [osg-users] [vpb] why the ive created by osgDem more beautiful than vpbmaster?

Hi, you can open the task files vpbmaster creates to compare vpbmasters osgdem call with your osgdem call. Compare the parameters to get the difference. Thank you! Cheers, Torben -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49313#49313

Re: [osg-users] post-rendering warping and off-axis projection

Depending on what you're projecting your channels onto (i.e. a spherical dome surface), you may need to come up with some asymmetrical custom frustums for each channel so as to minimize overlap and edge blending artifacts... -Original Message- From:

Re: [osg-users] [osgPlugins] osgShadow LiSPSM culling problem

Hi Garret, I have not worked on Lispsm for long time but description of your problem may suggest that my method of obtaining main camera and its projection matrix may not work as it used to or your setup uses unusual multi channel master / slave configuration that was not tested so far. I am
