RefCounted

public final class GLGraphicsPipeline
extends GraphicsPipeline

This class manages a GPU program and records per-program information. It also records the vertex and instance attribute layouts that are to be used with the program.

This class holds onto a GLProgram object that we use for draws. Besides storing the actual GLProgram object, this class is also responsible handling all uniforms, buffers, samplers, and other similar objects that are used along with the GLProgram and GLVertexArray in the draw. This includes both allocating and freeing these objects, as well as updating their values.

Supports OpenGL 3.3 and OpenGL 4.5.

bindIndexBuffer

public void bindIndexBuffer(@RawPtr
 @NonNull @RawPtr GLBuffer buffer)

Set element buffer (index buffer).

Bind pipeline first.

Parameters:

buffer - the element buffer object, raw ptr

bindVertexBuffer
