Function Documentation

face_t * AllocFace

(

void

)

Allocate a new face.

Increases c_activefaces by one.

Returns

Pointer to the new face.

surface_t * AllocSurface

(

void

)

Allocate a new surface.

Increases c_activesurfaces by one.

Returns

Pointer to the new surface.

void FreeFace

(

face_t *

f

)

Free a face.

Only the first face will be freed. If the face is linked to another face, that face will have to be freed seperately.

Reduces c_activefaces by one.

Parameters

f	The face to free.

void FreeSurface

(

surface_t *

s

)

Free a surface.

Only the first surface will be freed. If the surface is linked to another surface, that surface will have to be freed seperately.

Reduces c_activefaces by one.

Parameters

s	The face to free.

surface_t * GatherNodeFaces

(

struct node_s *

headnode

)

Free the current node tree and return a new chain of the surfaces that have inside faces.

void MakeFaceEdges

(

struct node_s *

headnode

)

Give edges to all the faces in the bsp tree.

Parameters

headnode

The root of the bsp tree.

void SubdivideFace	(	struct visfacet_s *	f,
		struct visfacet_s **	prevptr
	)

Split any faces that are too big.

If the face is > options.subdivide_size in either texture direction, carve off a valid sized piece and insert the remainder in the next link.

Parameters

f	The face to subdivide.
prevptr	The address of the pointer to this face. For nice linked list manipulation.
