C++ (Cpp) FIndirectLightingCacheAllocation::SetParameters Examples

Example #1

File: IndirectLightingCache.cpp Project: zhaoyizheng0930/UnrealEngine

FIndirectLightingCacheAllocation* FIndirectLightingCache::CreateAllocation(int32 BlockSize, const FBoxSphereBounds& Bounds, bool bPointSample, bool bUnbuiltPreview)
{	
	check(BlockSize > 1 || bPointSample);

	FIndirectLightingCacheAllocation* NewAllocation = new FIndirectLightingCacheAllocation();
	FIndirectLightingCacheBlock NewBlock;

	//@todo - don't allocate point samples from the layout, they don't go through the volume texture
	if (AllocateBlock(BlockSize, NewBlock.MinTexel))
	{
		NewBlock.TexelSize = BlockSize;
		CalculateBlockPositionAndSize(Bounds, BlockSize, NewBlock.Min, NewBlock.Size);

		FVector Scale;
		FVector Add;
		FVector MinUV;
		FVector MaxUV;
		CalculateBlockScaleAndAdd(NewBlock.MinTexel, NewBlock.TexelSize, NewBlock.Min, NewBlock.Size, Scale, Add, MinUV, MaxUV);

		VolumeBlocks.Add(NewBlock.MinTexel, NewBlock);
		NewAllocation->SetParameters(NewBlock.MinTexel, NewBlock.TexelSize, Scale, Add, MinUV, MaxUV, bPointSample, bUnbuiltPreview);
	}

	return NewAllocation;
