Definition at line 958 of file gcm_sys.h.

cubemap

u8 _gcmTexture::cubemap

Indicates if this is a cube-mapped texture.

Possible values are:

• GCM_TRUE
• GCM_FALSE

Definition at line 920 of file gcm_sys.h.

• GCM_TEXTURE_DIMS_3D

Definition at line 912 of file gcm_sys.h.

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_B8
• GCM_TEXTURE_FORMAT_A1R5G5B5
• GCM_TEXTURE_FORMAT_A4R4G4B4
• GCM_TEXTURE_FORMAT_R5G6B5
• GCM_TEXTURE_FORMAT_A8R8G8B8

• GCM_TEXTURE_FORMAT_A8L8

Definition at line 895 of file gcm_sys.h.

height

u16 _gcmTexture::height

Texture height in pixels.

Definition at line 947 of file gcm_sys.h.

location

u8 _gcmTexture::location

Location of texture.

Possible values are:

• GCM_LOCATION_RSX
• GCM_LOCATION_CELL

Definition at line 956 of file gcm_sys.h.

mipmap

u8 _gcmTexture::mipmap

Indicates if this is a mip-mapped texture.

Possible values are:

• GCM_TRUE
• GCM_FALSE

Definition at line 903 of file gcm_sys.h.

offset

u32 _gcmTexture::offset

Offset of texture data.

Definition at line 962 of file gcm_sys.h.

pitch

u32 _gcmTexture::pitch

Size of a texture line in bytes.

Definition at line 960 of file gcm_sys.h.

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)

width

u16 _gcmTexture::width

Texture width in pixels.

Definition at line 945 of file gcm_sys.h.
