This is the main repository for GPipe 2, a library which encapsulates OpenGL and provides a minimal type safe interface. Check out the release announcement, GPipe is dead, long live GPipe! or read on for the tutorials.

There is a series of five tutorials for learning the features of GPipe 2 hosted at http://tobbebex.blogspot.se (see below for a table of contents). You'll start with a simple triangle example, and advance through all of the encapsulated features of OpenGL that GPipe exposes.

Clone GPipe-Test and build it with Haskell Stack $ stack build. This is the example from Part 1, below.

  • Buffers
  • Vertex arrays
  • Primitive arrays
  • Index arrays
  • Instanced primitive arrays

  • Enough of that, back to the shader
  • Linear algebra in GPipe
  • Uniforms
