Function Documentation

void _math_init_translate

(

void

)

void _math_trans_1f	(	GLfloat *	to,
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	start,
		GLuint	n
	)

Array translation.

For example, convert array of GLushort[3] to GLfloat[4]. The function name specifies the destination format/size.

Parameters:

	to	the destination address
	ptr	the source address
	stride	the source stride (in bytes) between elements
	type	the source datatype (GL_SHORT, GL_UNSIGNED_INT, etc)
	size	number of values per element in source array (1,2,3 or 4)
	start	first element in source array to convert
	n	number of elements to convert

Note: "element" means a tuple like GLfloat[3] or GLubyte[4].

void _math_trans_1ub	(	GLubyte *	to,
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	start,
		GLuint	n
	)

Translate vector of values to GLubyte [1].

void _math_trans_1ui	(	GLuint *	to,
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	start,
		GLuint	n
	)

Translate vector of values to GLuint [1].

void _math_trans_3fn	(	GLfloat *	to[3],
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	start,
		GLuint	n
	)

Translate vector of values to GLfloat[3], normalized to [-1, 1].

void _math_trans_4chan	(	GLchan *	to[4],
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	size,
		GLuint	start,
		GLuint	n
	)

Translate vector of values to GLchan [4].

void _math_trans_4f	(	GLfloat *	to[4],
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	size,
		GLuint	start,
		GLuint	n
	)

Convert to floats w/out normalization (i.e.

just cast)

void _math_trans_4fn	(	GLfloat *	to[4],
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	size,
		GLuint	start,
		GLuint	n
	)

Convert to normalized floats in [0,1] or [-1, 1].

void _math_trans_4ub	(	GLubyte *	to[4],
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	size,
		GLuint	start,
		GLuint	n
	)

void _math_trans_4us	(	GLushort *	to[4],
		CONST void *	ptr,
		GLuint	stride,
		GLenum	type,
		GLuint	size,
		GLuint	start,
		GLuint	n
	)
