GpuTextureUsages Enumeration

Enum describing buffer usage; not mutually exclusive.

Namespace:  NeoAxis
Assembly:  NeoAxis.Core (in NeoAxis.Core.dll) Version: 2022.1.1.0 (2022.1.1.0)
public enum Usages
  Member nameValueDescription
Static1 Static buffer which the application rarely modifies once created. Modifying the contents of this buffer will involve a performance hit.
Dynamic2 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.
WriteOnly4 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.
StaticWriteOnly5 Combination of Static and WriteOnly.
DynamicWriteOnly6 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.
BlitDestination7 Texture can be used as the destination of a blit operation.
DynamicWriteOnlyDiscardable14 Combination of Dynamic, WriteOnly and Discardable.
AutoMipmap256 Mipmaps will be automatically generated for this texture.
RenderTarget512 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.
ReadBack1024 Texture data can be read back.
