[osg-users] osgCal2 and animation blending

Hi list, I have a question about the Cal3D wrapper for OSG, osgCal2; this list is not exactly for that project, but someone pointed me to this list in case I had trouble. I can't seem to be able to properly blend animations. Check this code: #include osg/PositionAttitudeTransform #include

[osg-users] Environment cube mapping more than one object problem

Hi list, I'm trying to set a cube map to do environment mapping, based on the osgprerendercubemap example; it works fine, as long as it's just one object that uses the reflection. It's like the cameras are only updated for the last object that the reflection is applied to, as the position of the

[osg-users] How to hide a RTT camera's clear color

Hi all, I have a RTT camera for cube mapped reflections; it now works well, except that I want to show only the reflected objects, not the clear color, when applied to an object; I have tried using the clear color's alpha with TexEnv, TexEnvCombine and AlphaFunc but I never got the result I

Re: [osg-users] How to hide a RTT camera's clear color

Hi again, I have already set my RTT color buffer as RGBA; the texture attached to the camera is an osg::TextureCubeMap that I'm setting it up with texture-setInternalFormat( GL_RGBA ); texture-setSourceFormat( GL_RGBA ); texture-setSourceType( GL_FLOAT ); and using std::cerr

Re: [osg-users] How to hide a RTT camera's clear color

Hi list... I have been trying to get a camera with a texture attached to hide the clear color with it's alpha value, but I have been unable to; after searching yet again through the mailing list archives, I found someone who wrote that switching it's render target's implementation sort of solved

[osg-users] How to hide a RTT camera's clear color [SOLVED]

Hi list, just in case another soul has a similar issue; setting the render implementation to anything but the frame buffer ( and obviously a separate window ) works fine. The slowness with FBOs was caused because I was filling up my modest 64MB videocard's memory. My bad. So if the same happens

[osg-users] Render to texture multiple cameras into one texture

Hi list, I have 4 cameras independent of each other, and each one covers a 4th of the screen. I want to take a screenshot of each one then put the 4 images into a single texture. Also note that I'm not using the composite viewer. My first problem is that the normal approach is to attach a

[osg-users] 1D texture loading by model loading plugins

Hi list, it seems that currently none of the model loading plugins can load a 1D texture( did a quick grep for Texture1D ), except the .osg and .ive formats. If you try loading a .png file with a height and depth of 1, loading fails( as it probably tries to load it as a Texture2D ), and , and I'm

[osg-users] Changing OSG License to GPL

Hi list, I'm interested in taking some code from osgFX( particulary cartoon and bump mapping ), modifying it, and putting the result under the GPL. Since the OpenSceneGraph Public License is based on the LGPL, and the LGPL permits switching to the GPL, you would think I just have to change any

Re: [osg-users] Changing OSG License to GPL

Hi list, @Sergey Kurdakov: sorry but it is really not clear why LGPL prohibits you to The LGPL itself does not prohibits me to use the GPL, in fact, it explicitly permits it. However, the page http://www.openscenegraph.org/projects/osg/wiki/Legal, probably written by Robert( it's down now, so

Re: [osg-users] osg-users Digest, Vol 22, Issue 53

Hi list, @Jan Ciger: Regarding multiple licenses - you will still have them, due to the OSG dependencies (zlib license, JPEG library license, ...) Yes, but I'm not the one that maintains OSG's dependencies. However, a much nicer approach would be to contribute the changes you want to make

[osg-users] Drawing a line once( bullet physics integration )

Hi all, I'm trying to integrate bullet with osg; the problem comes with bullet's debug drawing. Bullet has an abstract class, with drawing functions to be implemented by the user. The main requirement is simply to render a line; however I need to draw a single frame, not add a model to a scene
