gDPSetTileSize [Macro]

Function

gDPSetTileSize

Sets the tile descriptor parameters

Syntax

#include <ultra64.h>        /* gbi.h */
gDPSetTileSize(Gfx *gdl, u32 tile, u32 uls, u32 ult, u32 lrs, u32 lrt )
gsDPSetTileSize(         u32 tile, u32 uls, u32 ult, u32 lrs, u32 lrt )

Arguments

gdl

Display list pointer.

tile

Tile descriptor index (3-bit precision, 0~7).

uls

Texture tile's upper-left s coordinate (10.2, 0.0~1023.75).

ult

Texture tile's upper-left t coordinate (10.2, 0.0~1023.75).

lrs

Texture tile's lower-right s coordinate (10.2, 0.0~1023.75).

lrt

Texture tile's lower-right t coordinate (10.2, 0.0~1023.75).

Description

Sets the parameters of a tile descriptor defining the origin and range of a texture tile.

uls, ult

Defines the s,t texture coordinates at the tile origin. This is used when shifting a texture to straddle the face of a polygon. It also defines the lower-limit boundary when clamping.

lrs, lrt

Used when clamping to define the upper-limit boundary.

For details, see Section 13.4.9 "SL, TL" Section 13.4.10 "SH, TH" and Section 13.5 "Tile Descriptor Loading" in the N64 Programming Manual.
