GXSetScissor

C Specification

#include <revolution/gx.h>

void GXSetScissor(
u32 xOrig,
u32 yOrig,
u32 wd,
u32 ht);

Arguments

`xOrig`	Scissorbox left-most coordinate in screen coordinates.
`yOrig`	The scissor box's top-most coordinate in screen coordinates.
`wd`	The scissor box's width in screen coordinates.
`ht`	The scissor box's height in screen coordinates.

Return Values

None.

Description

The scissor box specifies an area of the screen where primitives are not culled. This function sets the scissor box in screen coordinates. The screen origin (xOrig=0, yOrig=0) is at the top left corner of the display.

The values may range within [0 ... 2047]. Using values that extend beyond the EFB size is allowable since the scissor box may be repositioned within the EFB using the command GXSetScissorBoxOffset.

By default, the scissor box is set to match the viewport rectangle. GXInit initializes the scissor box to match the viewport given the current render mode.
