Â« Chapter 2.1 | Table of Contents | Chapter 2.3 Â» Buffers and textures contain the raw materials for an OpenGL program, but without shaders, they are inert lumps of bytes. If you recall from our overview of the graphics pipeline, rendering requires a vertex shader, which maps our vertices into screen space, and a fragment shader, which colors in the rasterized fragments of the resulting triangles.
