WebRenderbuffer Objects. Unconventional objects: Sync Objects. Shader and program objects. A texture is an OpenGL Object that contains one or more images that all have the same image format. A texture can be used in two ways: it can be the source of a texture access from a Shader, or it can be used as a render target. WebDetailed Description. The QOpenGLFramebufferObject class encapsulates an OpenGL framebuffer object, defined by the GL_EXT_framebuffer_object extension.

I have set up FBOs (GL_FRAMEBUFFER_EXT, color and depth buffers) and my app is rendering a simple OpenGL 3D object (a rotating teapot) to texture with a NULL image. I am trying to capture pixel data using glReadPixels. I see the 3D object correctly on the screen. But glReadPixels gives junk data. flying a knivesWeb16 de mar. de 2024 · A texture is attached to that FBO. The result is that I now render to that texture. If I want to get that rendered texture's pixels, I can use glReadPixels(), but that is slow, since it copies the pixels with the CPU.
