Variable documentation

TextureDesc Diligent::DynamicTextureAtlasCreateInfo::Desc

Texture description.

Texture type must be 2D or 2D array. When the type is texture 2D, resizes will be disabled.

Uint32 Diligent::DynamicTextureAtlasCreateInfo::TextureGranularity

Texture region allocation granularity.

The width and height of the texture region will be aligned to the TextureGranularity value. Texture granularity must be power of two.

Uint32 Diligent::DynamicTextureAtlasCreateInfo::ExtraSliceCount

The number of extra slices.

When non-zero, the array will be expanded by the specified number of slices every time there is insufficient space. If zero, the array size will be doubled when more space is needed.

Uint32 Diligent::DynamicTextureAtlasCreateInfo::SuballocationObjAllocationGranularity

Allocation granularity for ITextureAtlasSuballocation objects.

Texture atlas uses FixedBlockMemoryAllocator to allocate instances of ITextureAtlasSuballocation implementation class. This memeber defines the number of objects in one page.
