Opengl ssbo example
WebDescription. glDrawElements specifies multiple geometric primitives with very few subroutine calls. Instead of calling a GL function to pass each individual vertex, normal, texture coordinate, edge flag, or color, you can prespecify separate arrays of vertices, normals, and so on, and use them to construct a sequence of primitives with a single ...

WebDescription. glCreateBuffers returns n previously unused buffer names in buffers, each representing a new buffer object initialized as if it had been bound to an unspecified targe Web4.3. Core ARB extension. ARB_compute_shader. A Compute Shader is a Shader Stage that is used entirely for computing arbitrary information. While it can do rendering, it is generally used for tasks not directly related to drawing triangles and pixels.

As an example: If we dispatch a work group count of [64, 1, 1] with a compute shader local size of [32, 32, ,1], our compute shader will be invoked 64 x 32 x 32 = 65,536 times.
WebDescription. glMapBuffer and glMapNamedBuffer map the entire data store of a specified buffer object into the client's address space. The data can then be directly read and/or written relative to the returned pointer, depending on the specified access policy.
