[FlagsAttribute] public enum Usages
Members| Member name | Value | Description | |
|---|---|---|---|
| Static | 1 | Static buffer which the application rarely modifies once created. Modifying the contents of this buffer will involve a performance hit. | |
| Dynamic | 2 | Indicates the application would like to modify this buffer with the CPU fairly often. Buffers created with this flag will typically end up in AGP memory rather than video memory. | |
| WriteOnly | 4 | Indicates the application will never read the contents of the buffer back, it will only ever write data. Locking a buffer with this flag will ALWAYS return a pointer to new, blank memory rather than the memory associated with the contents of the buffer; this avoids DMA stalls because you can write to a new memory area while the previous one is being used. | |
| StaticWriteOnly | 5 | Combination of Static and WriteOnly. | |
| DynamicWriteOnly | 6 | Combination of Dynamic and WriteOnly. If you use this, strongly consider using DynamicWriteOnlyDiscardable instead if you update the entire contents of the buffer very regularly. | |
| BlitDestination | 7 | Texture can be used as the destination of a blit operation. | |
| DynamicWriteOnlyDiscardable | 14 | Combination of Dynamic, WriteOnly and Discardable. | |
| AutoMipmap | 256 | Mipmaps will be automatically generated for this texture. | |
| RenderTarget | 512 | This texture will be a render target, ie. used as a target for render to texture setting this flag will ignore all other texture usages except AutoMipmap. | |
| ReadBack | 1024 | Texture data can be read back. | |
| ComputeWrite | 2048 |
