Hi;
I create a OffscreenBuffer just like:
GLint oldFBO;
glGetIntegerv(GL_FRAMEBUFFER_BINDING, &oldFBO);
glGenFramebuffers(1, &myFramebufferID);
glGenRenderbuffers(1, &myDepthID);
glGenTextures(1, &myTextureID);
glBindFramebuffer(GL_FRAMEBUFFER, myFramebufferID);
........//create my off screen buffer, bingding it, and then do my job in it.
//In the end put the saved FBO back.
glBindFramebuffer(GL_FRAMEBUFFER, oldFBO);
After put the saved FBO back, I saved the OffscreenBuffer as a picture and it turned out very well.but it do not display in rhino viewport.I am sorry that my English is not so good. I hope I have described my problem correctly.What I want to ask is, does RHINO SDK have interfaces to pass in data from the OpenGL off screen buffer.
