GXGetTexRegionAll

Syntax

#include <revolution/gx.h>

void GXGetTexRegionAll(
    const GXTexRegion*  region,
    GXBool*             is_32b_mipmap,
    u32*                tmem_even,
    u32*                size_even,
    u32*                tmem_odd,
    u32*                size_odd );

Arguments

region Pointer to a GXTexRegion structure
is_cached Returns whether this is a cached region or a preloaded region.
is_32b_mipmap Returns whether or not the cached region is intended for a 32-bit (RGBA8) mipmap texture.
tmem_even Returns the texture memory address for the even LODs or for planar (non-32b) textures.
size_even Returns the size (in bytes) of the texture memory region for the even LODs.
Note that the value is not doubled for 32-bit mipmap textures.
tmem_odd Returns the texture memory address for the odd LODs (if any).
size_odd Returns the texture memory region size (in bytes) for the odd LODs.
Note: The value is not doubled for 32-bit mipmap textures.

Return Values

None.

Description

This function returns all the parameters that describe a texture memory region (GXTexRegion structure) object. This object describes how texture memory needs to be used. There are two types of texture memory region objects. The first is a cache texture (created by the GXInitTexCacheRegion function), while the other is a preload texture (created by the GXInitTexPreLoadRegion function).
