WebTo implement 3D picking we will take advantage of an OpenGL feature that was introduced in the shadow map tutorial (#23) - the Framebuffer Object (FBO). Previously we used the FBO for depth buffering only because we were interested in comparing the depth of a pixel from two different viewpoints. WebI hesitate between these 3: 1 FBO for everything, change attachment but don't switch between FBOs. 1 FBO for each render target (size + format) in the rendering path. That …

Web29 de dez. de 2016 · You either bind depth texture to fbo, or renderbuffer with depth format storage. You go with texture if later you'll need to sample rendered depth surface, and you go with renderbuffer if you don't need actual result.
