QtOpenGL development (3) shader programming
All operations in OpenGL are performed in three-dimensional space, but screens and windows are composed of two-dimensional pixels. So a large part of OpenGL’s work is to convert three-dimensional coordinate primitive information into two-dimensional pixels on the screen. In OpenGL, this three-dimensional to two-dimensional conversion process is managed by the rendering pipeline (graphics pipeline). The […]
