Rendering pipeline

Question 39

This initial stage involves defining and organizing the raw vertex data (positions, colors, texture coordinates, normals, etc.) in memory, typically using Vertex Buffer Objects (VBOs) and Vertex Array Objects (VAOs).

Accepted Answer

Vertex Specification

Question 40

This is the first programmable stage. The vertex shader processes each transformations (like vertex individually, performing model-view-projection), calculations, and passing data to subsequent stages.

Vertex Shader

Question 41

After vertex processing, vertices are assembled into primitives like points, lines, or triangles, based on the specified drawing mode
