TextureSubResData()

Diligent::TextureSubResData::TextureSubResData ( )

inlineconstexprnoexcept

Initializes the structure members with default values.

Default values:

Member	Default value
pData	nullptr
SrcOffset	0
Stride	0
DepthStride	0

Member Data Documentation

DepthStride

Uint64 Diligent::TextureSubResData::DepthStride = 0

For 3D textures, depth slice stride in bytes.

On OpenGL, this must be a multiple of Stride

pData

const void* Diligent::TextureSubResData::pData = nullptr

Pointer to the subresource data in CPU memory.

If provided, pSrcBuffer must be null

pSrcBuffer

struct IBuffer* Diligent::TextureSubResData::pSrcBuffer = nullptr

Pointer to the GPU buffer that contains subresource data.

If provided, pData must be null

SrcOffset

Uint64 Diligent::TextureSubResData::SrcOffset = 0

When updating data from the buffer (pSrcBuffer is not null), offset from the beginning of the buffer to the data start
