WebOpenGL doesn't explicitly define neither camera object nor a specific matrix for camera transformation. Instead, OpenGL transforms the entire scene inversely to the eye space, where a fixed camera is at the origin (0,0,0) and always looking along -Z axis. ... Framebuffer object (FBO) ...

WebOpenGL renders to framebuffers. By default OpenGL renders to screen, the default framebuffer that commonly contains a color and a depth buffer. This is great for many purposes where a pipeline consists of a single pass, a pass being a sequence of shaders. For instance a simple pass can have only a vertex and a fragment shader. WebIn this video we complete the development of the camera by adding mouse support and calculating the camera rotations using Quaternions. This allows us to rot... software haussoft

"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. In your example you create depth texture, but it's not used anywhere. " - Opengl shrinking fbo breaks camera
