opengl logger / debugger

I'm looking for people to help me develop my opengl logger into a debugger. ie warn of incorrect gl commands in beween
glbegin and glend etc.

very early yet lots to be done!
pointers are just expressed as ints and gl enums are also ints instead of say "GL_MODELMATRIX"

contact me directly via my profile email if you are interested in helping
(just a thought from the info I'm getting you could store an opengl display list and see what tri's are being rendered from any point of view...)


just put this at the top of your code
Import "../gllogger/opengllogger.bmx"

heres some sample output

starting to make some function human readable

This is helpful in most cases:

Local err:Int = glGetError()
If (err <> 0) Then
	Select err
		Case GL_INVALID_ENUM
			If Not Proceed ("OpenGL Error: GLenum argument out of range. Proceed?",1) Then End
		Case GL_INVALID_ENUM
			If Not Proceed ("OpenGL Error: GLenum argument out of range. Proceed?",1) Then End
		Case GL_INVALID_VALUE
			If Not Proceed ("OpenGL Error: Numeric argument out of range. Proceed?",1) Then End
		Case GL_INVALID_OPERATION
			If Not Proceed ("OpenGL Error: Operation illegal in current state. Proceed?",1) Then End
		Case GL_STACK_OVERFLOW
			If Not Proceed ("OpenGL Error: Function would cause a stack overflow. Proceed?",1) Then End
		Case GL_STACK_UNDERFLOW
			If Not Proceed ("OpenGL Error: Function would cause a stack underflow. Proceed?",1) Then End
		Case GL_OUT_OF_MEMORY
			If Not Proceed ("OpenGL Error: Not enough memory left to execute function. Proceed?",1) Then End
		Default
			If Not Proceed ("Unknown OpenGL Error. Proceed?",1) Then End
	End Select
EndIf

If it is not already part of your module.

neat! I'd have got round to it, but it doesnt look like anyones interested, the main thing is that it does rather demonstrate the power of max that you can do these sorts of things
