]> Announcement CamlGL --- OpenGL bindings for Objective Caml http://www.sf.net/projects/camlgl Key Features: - Full OpenGL 1.4 support - All window system independent ARB extensions supported - All published NVidia extensions supported (including NV30) - All ATI extensions supported - Windows and Linux version - GLFW bindings - unsupported Glut and SDL bindings ----------------------------------------------------------- WARNING this release was tested under RH8, gcc3.2, NVidia GL 41.91 ----------------------------------------------------------- Details ======= 1. CamlGL loads GL library at runtime. So you can switch between Native/Mesa without recompiling. (This is currently not supported under Windows) Gl.set_gl_lib "libGL.so.1" 2. CamlGL uses "plain" naming conversion for functions and enums. glEnable cgl_lighting; (* glEnable(GL_LIGHTING); *) glVertex3f 1.0 0.0 0.0; (* glVertex3f(1.0f,1.0f,1.0f); *) glColor3b 255 255 255; (* glColor3b(255,255,255); *) 3. CamlGL uses Bigarray module for array representation. let a = Hgl.ba_float_init [|1.0;0.0;3.0|] in glVertex3fv a; ------------------------------------------------------------- Notes ====== 1. GL_ALL_ATTRIB_BITS GL_ALL_ATTRIB_BITS declared as 0xFFFFFFFF in NVidia header. Mesa defines it as 0xFFFF. We are using Mesa constant. 2. GL_ALL_CLIENT_ATTRIB_BITS and GL_CLIENT_ALL_ATTRIB_BITS Declared as 0xFFFFFFFF. We are using 0x3FFFFFFF. 3. Functions with standard type string glGetString: int -> string glLoadProgramNV: int -> int -> int -> string -> unit glProgramNamedParameter4{fd}[v]NV: int -> int -> string -> ... -> unit glGetProgramNamedParameter{fd}vNV: int -> int -> string -> 'a -> unit glProgramStringARB: int -> int -> int -> string -> unit 4. GL_NV_vertex_array_range VAR depends on two window system specific functions: - {glX,wgl}AllocateMemoryNV - {glX,wgl}FreeMemoryNV We provide standard bindings for them: val _glAllocateMemoryNV: int -> float -> float -> float -> tbabyte val _glFreeMemoryNV: tbaabstract -> unit See example in demos/simple/vatest. 5.
