sw_span_arrays Struct Reference

#include <s_span.h>

---

Detailed Description

Arrays of fragment values.

These will either be computed from the span x/xStep values or filled in by glDraw/CopyPixels, etc. These arrays are separated out of sw_span to conserve memory.

Data Fields
GLfloat	attribs [FRAG_ATTRIB_MAX][MAX_WIDTH][4]
	Per-fragment attributes (indexed by FRAG_ATTRIB_* tokens).
GLubyte	mask [MAX_WIDTH]
	This mask indicates which fragments are alive or culled.
GLenum	ChanType
	Color channel type, GL_UNSIGNED_BYTE, GL_FLOAT.
GLubyte	rgba8 [MAX_WIDTH][4]
	Attribute arrays that don't fit into attribs[] array above.
GLushort	rgba16 [MAX_WIDTH][4]
GLchan(*	rgba )[4]
GLint	x [MAX_WIDTH]
	either == rgba8 or rgba16
GLint	y [MAX_WIDTH]
	fragment Y coords
GLuint	z [MAX_WIDTH]
	fragment Z coords
GLuint	index [MAX_WIDTH]
	Color indexes.
GLfloat	lambda [MAX_TEXTURE_COORD_UNITS][MAX_WIDTH]
	Texture LOD.
GLfloat	coverage [MAX_WIDTH]
	Fragment coverage for AA/smoothing.
