Graphics

Image Manipulation

• stb_image: OCaml bindings to the C stb_image library. Loads images into BigArrays.
• camlimages: Image manipulation library for different image formats.
• imagelib: Read and write various image formats. Backed by BigArrays. Only PNGs and BMPs are supported – other formats are converted to PNG first.

2D

• Wall: Vector drawing library using OpenGL as the backend.
  • Presentation on Wall at ICFP
• archimedes: 2D plotting library.
• cairo2: Bindings to Cairo, a 2D Vector Graphics Library. Integrates well with lablgtk.
• Vg: Declarative 2D vector graphics for OCaml.
• owl_base: Part of Owl. This is essential for manipulating BigArrays efficiently (with vectorized operations), for graphics and such.

3D

• tgls: Thin bindings to OpenGL 3.{2,3},4.{0,1,2,3,4} and OpenGL ES {2,3}. This is the recommended library for OpenGL support in OCaml.
  • tgls OpenGL hello world
• glMLite: OpenGL bindings for OCaml. Provides an experimental functional API.
• lablgl: Interface to OpenGL and GLUT, a simple framework for creating simple applications with OpenGL.
• glfw-ocaml: Bindings to GLFW, an OpenGL library providing OS-specific functionality, such as window, surface and input management.
• ocaml-glfw: Another library with bindings to GLFW.
• ZENITH: A wireframe render with support for .obj models and simple materials

Linear Algebra

• Owl: Numerical library, useful for fast linear algebra operations. See the Owl Manual for details.
• reason-gl-matrix: Bindings to glm, the OpenGL linear algebra C++ library for graphics.
