OpenGL ES 2.0 - Programmable Shading. OpenGL ES 2.0 was the first portable mobile graphics API to expose programmable shaders in the then latest generation of graphics hardware. It remains a prevalent API today, and still is the most widely available 3D graphics API, and remains a solid choice to target the widest range of devices in the market.

Description. glDrawBuffers and glNamedFramebufferDrawBuffers define an array of buffers into which outputs from the fragment shader data will be written. If a fragment shader writes a value to one or more user defined output variables, then the value of each variable will be written into the buffer specified at a location within bufs corresponding to the location …Sep 8, 2019 · Main options.
