Everything is done for you… However, once you start wondering about rendering to an image (e.g. with the semantically equivalent. If you enable linear filtering of your shadow map, instead of returning exactly 1.0 or 0.0, sampler2DShadow will fetch the 4 nearest depths, perform 4 individual tests against your R coordinate and then return the average value. But instead it only fills the first depth texture with depth information: No Pixel Shader. I am trying to add simple shadow mapping to my friends gles 2.0 app. GLFW for C#. Thanks a lot for forwarding this! You could always draw the texture to the screen instead of processing the color.. then you can see if the colors are drawing correctly.

To subscribe to this RSS feed, copy and paste this URL into your RSS reader. These buffers occupy video memory like any other OpenGL object, but so far we've had little control over them besides specifying the pixel formats when you created the OpenGL context. Specify the target to which the framebuffer is bound for glCheckFramebufferStatus, and the target against which framebuffer completeness of framebuffer is checked for glCheckNamedFramebufferStatus . Specifies the name of the framebuffer object for glCheckNamedFramebufferStatus So in your case, you didn’t have a bound GL context, causing glCheckFramebufferStatus() to return 0. Bind the second FBO and call glClear. I use twirl shader for achieve twirl effect. I called this just before I call glBindFramebuffer(GL_FRAMEBUFFER, 0); after creating the Frame buffer the first time and inside the render loop.
