Public Functions

GFXGLTextureObject(GFXDevice * aDevice, GFXTextureProfile * profile)

~GFXGLTextureObject()

void

bind(U32 textureUnit)

Binds the texture to the given texture unit and applies the current sampler state because GL tracks filtering and wrapper per object, while GFX tracks per sampler.

bool

copyToBmp(GBitmap * )

Not implemented.

const String

describeSelf()

The resource should put a description of itself (number of vertices, size/width of texture, etc.) in buffer.

lock(U32 mipLevel, RectI * inRect)

Get/set data from texture (for dynamic textures and render targets)

void

reInit()

void

release()

void

reloadFromCache()

Reloads texture from zombie cache, used by GFXGLTextureManager to resurrect the texture.

void

resurrect()

When called the resource should restore all device sensitive information destroyed by zombify()

void

unlock(U32 mipLevel)

Releases a lock previously acquired.

void

zombify()

When called the resource should destroy all device sensitive information (e.g. D3D resources in D3DPOOL_DEFAULT.
