Re: [osg-users] importing shaders

Hello, Hope it helps, .osg files can have shaders in them. Like the Julia file with the fractals. (It's in the data that comes with the OSG). Guy. I have a model made in 3DS with textures and shaders and I would like to use it within OSG. When I try displaying it with osgviewer.exe the

Hi, I guess it depends on your platform. I haven't seen generic implementation for it but I guess it could be added to display settings or something like that (maybe GraphicsContext::Traits). Anyway, on windows platform, in the file \osgViewer\GraphicsWindowWin32.cpp, In the function void

Hi, We write to all the channels and there doesn't seem to be any trouble. But be carefull, if u write to the alpha channel and blending is on, it will use these values. Can't you write your data into other channel or to a separate image (another attachment like COLOR_BUFFER1. in the shader it

[osg-users] questions about boundingBox and contains()

hi, as far as i understand every Drawable object in the scenegraph does have a _boundingBox data member. * does the user have to manually initalize this boundingBox (with a call like myDrawableOject.computeBound()), or has it already been set by osg to nodes' geometry extent (xmin, xmax,

Re: [osg-users] Strange setImage behaviour

Max, For starters, you probably want GL_RGB8 (0x8051) and not GL_TEXTURE_2D (0x0DE1) in your setImage call. But in general it looks a bit odd to me, and I'm not sure what your intention was. First you get the pointer to the textures image, and then you set it to something else. I imagine you
