Hi, I need to make a render to texture in order to use the texture in a displacement mapping shader. I seen in osgPrerenderer example to attach texture to cameranode. it's necessary for displacement vertex program that the Image that used is stored in GL_RGBA_FLOAT32_ATI internal format , but I 'm not able to get a prerenderer in this format. Does someone can explain me how to use a prerenderer in displacement vertex program?
thank's Ben
