WebRenderbuffer Objects are OpenGL Objects that contain images. They are created and used specifically with Framebuffer Objects.They are optimized for use as render targets, while Textures may not be, and are the logical choice when you do not need to sample (i.e. in a post-pass shader) from the produced image. If you need to resample (such as when … WebThe framebuffer is constantly updated in a non-UI thread. The rendering result is a basic rotating quad mesh where the shading is done with vertex colors. The example uses OpenGL 3.3 pipeline for rendering. The rendering is done using native OpenGL API, not with Qt OpenGL classes. The matrix and quaternion math is done with GLM library.
