Function Documentation

pvr_poly_cxt_col()

void pvr_poly_cxt_col	(	pvr_poly_cxt_t *	dst,
		pvr_list_t	list
	)

Fill in a polygon context for non-textured polygons.

This function fills in a pvr_poly_cxt_t with default parameters appropriate for rendering a non-textured polygon in the given list.

Parameters

dst	Where to store the polygon context.
list	The primitive list to be used.

pvr_poly_cxt_col_mod()

void pvr_poly_cxt_col_mod	(	pvr_poly_cxt_t *	dst,
		pvr_list_t	list
	)

Fill in a polygon context for non-textured polygons affected by a modifier volume.

This function fills in a pvr_poly_cxt_t with default parameters appropriate for rendering a non-textured polygon in the given list that will be affected by modifier volumes.

Parameters

dst	Where to store the polygon context.
list	The primitive list to be used.

pvr_poly_cxt_txr()

		pvr_list_t	list,
		int	textureformat,
		int	tw,
		int	th,
		pvr_ptr_t	textureaddr,
		int	filtering
	)

Fill in a polygon context for a textured polygon.

This function fills in a pvr_poly_cxt_t with default parameters appropriate for rendering a textured polygon in the given list.

Parameters

dst	Where to store the polygon context.
list	The primitive list to be used.
textureformat	The format of the texture used.
tw	The width of the texture, in pixels.
th	The height of the texture, in pixels.
textureaddr	A pointer to the texture.
