Tgls — Thin bindings to OpenGL {3,4} and OpenGL ES {2,3} for OCaml

Tgls is a set of independent OCaml libraries providing thin bindings to OpenGL libraries. It has support for core OpenGL 3.{2,3} and 4.{0,1,2,3,4} and OpenGL ES 2 and 3.{0,1,2}.

Tgls depends on ocaml-ctypes and the C OpenGL library of your platform. It is distributed under the ISC license.

Installation

Tgls can be installed with opam:

opam install tgls

If you don't use opam consult the opam file for build instructions and a complete specification of the dependencies.

Supported OpenGL versions

Tgls provides four libraries:

• tgls.tgl3, supports all functions and enumerants to program with a core OpenGL 3.2 or OpenGL 3.3 context.

• tgls.tgl4, supports all functions and enumerants to program with a core OpenGL 4.0 to 4.5 context.

• tgls.tgles2, supports all functions and enumerants to program with an OpenGL ES 2.0 context.

• tgls.tgles3, supports all functions and enumerants to program with an OpenGL ES 3.0 to 3.2 context.

Compatibility contexts are not supported. For extensions, most of them only add few entry points and/or enumerants, as such it seems the easiest way to access them is to manually use ocaml-ctypes and the appropriate constants (the tools in support could be enhanced to support them but it's not planned to do so).

Documentation

The documentation can be consulted online or via odig doc tgls.

Questions are welcome but better asked on the OCaml forum than on the issue tracker.

Sample programs

A few sample programs can be found in test, you need tsdl to compile them.

The C file assert_sizes.c is a program that should exit with 0 on your platform to ensure the bindings will work correctly.
