GLvector4f Struct Reference

#include <m_vector.h>

---

Detailed Description

Wrap all the information about vectors up in a struct.

Has additional fields compared to the other vectors to help us track of different vertex sizes, and whether we need to clean columns out because they contain non-(0,0,0,1) values.

The start field is used to reserve data for copied vertices at the end of _mesa_transform_vb, and avoids the need for a multiplication in the transformation routines.

Data Fields
GLfloat(*	data )[4]
	may be malloc'd or point to client data
GLfloat *	start
	points somewhere inside of <data>
GLuint	count
	size of the vector (in elements)
GLuint	stride
	stride from one element to the next (in bytes)
GLuint	size
	2-4 for vertices and 1-4 for texcoords
GLbitfield	flags
	bitmask of VEC_x flags
void *	storage
	self-allocated storage
GLuint	storage_count
	storage size in elements
