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

v0.8.6

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 and corresponding ocamlfind packages:

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

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

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

  • 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 and API reference is automatically generated by from the interfaces, it can be consulted online or via odig doc tgls.

Sample programs

If you installed tgls with opam sample programs are located in the directory opam config var tgls:doc. Their source has a comment on how to compile them.

In the distribution sample programs are located in the test directory of the distribution. You'll need tsdl to compile them.

They can be built with:

ocamlbuild -use-ocamlfind tests.otarget

The resulting binaries are in _build/test :

  • linkgl{3,4,es2,es3}.native, tests that the C OpenGL library is correctly linked, the executables should exit with 0.

  • trigl{3,4,es2,es3}.native, opens a window and draws a tricolor triangle, needs tsdl.

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