Enumerator | |
---|---|
NotTexture | Texture cannot be used as a regular texture (bound to SRV in D3D11 terms) |
RenderToTexture | Texture can be used as an RTT (FBO in GL terms) |
Uav | Texture can be used as an UAV. |
AllowAutomipmaps | Texture can use mipmap autogeneration. This flag is NOT necessary for TextureFilter::TypeGenerateHwMipmaps, as this filter will create a temporary resource. AllowAutomipmaps is thought for RenderToTexture textures. |
AutomipmapsAuto | Texture will auto generate mipmaps every time it's dirty, automatically. Requires AllowAutomipmaps. |
MsaaExplicitResolve | MSAA rendering is an antialiasing technique. MSAA works by rendering to a special surface (an MSAA surface) and once we're done, "resolving" from MSAA surface into a regular texture for later sampling.
|
Reinterpretable | When present, you may be creating another TextureGpu that accesses the internal resources of this TextureGpu but with a different format (e.g. useful for viewing a PFG_RGBA8_UNORM_SRGB as PFG_RGBA8_UNORM) |
PrefersLoadingFromFileAsSRGB | Prefer loading FROM FILES as sRGB when possible. e.g. load PFG_RGBA8_UNORM as PFG_RGBA8_UNORM_SRGB This flag does not affect RenderTextures, UAVs, or manually created textures. If you're manually creating sRGB textures, set PFG_RGBA8_UNORM_SRGB directly |
RenderWindowSpecific | Indicates this texture contains a RenderWindow. In several APIs render windows have particular limitations:
|
RequiresTextureFlipping | |
ManualTexture | Indicates this texture will be filled by the user, and won't be loaded from file or a listener from within a worker thread. This flag is implicit if NotTexture, RenderToTexture or Uav are set. |
AutomaticBatching | When not present: The Texture is exactly the type requested (e.g. 2D texture won't get a 2D array instead) While a texture is transitioning to Resident, no 64x64 is used, but the 4x4 dummy one will be used instead (blank texture). When this bit is set: The Texture can be of a different type. Most normally we’ll treat 2D textures internally as a slice to a 2D array texture. Ogre will keep three API objects:
|
PoolOwner | For internal use. Indicates whether this texture is the owner of a TextureGpuManager::TexturePool, which are used to hold regular textures using AutomaticBatching |
DiscardableContent | When this flag is present, the contents of a RenderToTexture or Uav may not be preserved between frames. Useful for RenderToTexture which are written or cleared first. Must not be used on textures whose contents need to be preserved between frames (e.g. HDR luminance change over time) If this flag is present, either RenderToTexture or Uav must be present |
