#include <revolution/gx.h>void GXSetViewportv( const f32* vp );vp |
Floating point value array. The minimum array size is GX_VIEWPORT_SZ. |
None.
This function sets the viewport rectangle in screen coordinates using the array vp. The screen origin (xOrig=0.0f, yOrig=0.0f) is at the top left corner of the display. Floating point arguments allow the viewport to be adjusted by 1/2 line for interlaced field rendering modes. See GXSetViewportJitter. The viewport depth parameters are normalized coordinates from 0.0f - 1.0f. The GX API will convert the depth range values to proper scale values depending on the type and format of the Z buffer.
The function GXGetViewportv returns the viewport in vector form. The order of parameters in vp corresponds to the order of parameters in GXSetViewport.
f32 vp[GX_VIEWPORT_SZ];vp[0] = 0.0f; // xOrig
vp[1] = 0.0f; // yOrig
vp[2] = 640.0f; // width
vp[3] = 480.0f; // height
vp[4] = 0.0f; // near Z
vp[5] = 1.0f; // far Z
GXSetViewPortv( vp );The viewport is typically set using parameters derived from the current render mode. See Render Modes.
