Detailed Description

RSX Texture data structure.

Field Documentation

cubemap

u8 _gcmTexture::cubemap

Indicates if this is a cube-mapped texture.

Possible values are:

• GCM_TRUE
• GCM_FALSE

dimension

u8 _gcmTexture::dimension

Texture dimension.

Possible values are:

• GCM_TEXTURE_DIMS_1D
• GCM_TEXTURE_DIMS_2D
• GCM_TEXTURE_DIMS_3D

format

u8 _gcmTexture::format

Texture format.

This is an OR-ed combination of the following values:

• GCM_TEXTURE_FORMAT_SWZ
• GCM_TEXTURE_FORMAT_LIN
• GCM_TEXTURE_FORMAT_NRM
• GCM_TEXTURE_FORMAT_L8
• GCM_TEXTURE_FORMAT_A1R5G5B5
• GCM_TEXTURE_FORMAT_A4R4G4B4
• GCM_TEXTURE_FORMAT_R5G6B5
• GCM_TEXTURE_FORMAT_A8R8G8B8
• GCM_TEXTURE_FORMAT_DXT1
• GCM_TEXTURE_FORMAT_DXT3
• GCM_TEXTURE_FORMAT_DXT5
• GCM_TEXTURE_FORMAT_A8L8

location

u8 _gcmTexture::location

Location of texture. Possible values are:

• GCM_LOCATION_RSX
• GCM_LOCATION_CELL

mipmap

u8 _gcmTexture::mipmap

Indicates if this is a mip-mapped texture.

Possible values are:

• GCM_TRUE
• GCM_FALSE

remap

u32 _gcmTexture::remap

Color remapping bitfield.

Each of the texture color components (red, green, blue, alpha) can be remapped according to a specified remapping type. The type specifies that the component is either set to zero, all one bits, or takes value of one of the source components. All remapping types and values are to be OR-ed together.

For instance, to have the alpha component set to zero, the red and blue components swapped and the green component kept as-is, set the following value:

(GCM_TEXTURE_REMAP_TYPE_ZERO << GCM_TEXTURE_REMAP_TYPE_A_SHIFT)
| (GCM_TEXTURE_REMAP_TYPE_REMAP << GCM_TEXTURE_REMAP_TYPE_R_SHIFT)
| (GCM_TEXTURE_REMAP_COLOR_B << GCM_TEXTURE_REMAP_COLOR_R_SHIFT)
| (GCM_TEXTURE_REMAP_TYPE_REMAP << GCM_TEXTURE_REMAP_TYPE_G_SHIFT)
| (GCM_TEXTURE_REMAP_COLOR_G << GCM_TEXTURE_REMAP_COLOR_G_SHIFT)
| (GCM_TEXTURE_REMAP_TYPE_REMAP << GCM_TEXTURE_REMAP_TYPE_B_SHIFT)
| (GCM_TEXTURE_REMAP_COLOR_R << GCM_TEXTURE_REMAP_COLOR_B_SHIFT)
