I'm not sure I understand the why, but anyway - How did you customize the image you render to? That's likely in the vicinity of Code: pCam->setRenderTargetImplementation(/**/); /*and*/ pCam->attach(/**/); calls. wwwanghao wrote: > after that I want to display the image You need a geometry to display it onto. You attach st coordinates to tha tgeometry via a texCoordArray. What comes now on how deeply you interact with the gl. Pure OSG is that you add the texture to the geometry's geode's stateSet. For custom shaders you include an isampler2D uniform (with your 0-255 image) in the glsl source and set that uniform by using a osg::Uniform. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=60106#60106 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
