FPrimitiveRuntimeVirtualTextureLodInfo Struct Reference

#include <PrimitiveSceneInfo.h>

Public Types
enum	{ LodBiasOffset = 7 }

Public Attributes
uint16	MinLod: 4 = 0
uint16	MaxLod: 4 = 0
uint16	LodBias: 4 = 0
uint16	CullMethod: 1 = 0
uint16	CullValue: 3 = 0

Detailed Description

Lod data used for runtime virtual texture page rendering. Packed to reduce memory overhead since one of these is allocated per primitive.

Member Enumeration Documentation

anonymous enum

anonymous enum

LodBias is in range [-7,8] so is stored with this offset.

Member Data Documentation

CullMethod

uint16 FPrimitiveRuntimeVirtualTextureLodInfo::CullMethod

Culling method used to remove the primitive from low mips of the runtime virtual texture. 0: CullValue is the number of low mips for which we cull the primitive from the runtime virtual texture. 1: CullValue is the pixel coverage threshold at which we cull the primitive from the runtime virtual texture.

CullValue

uint16 FPrimitiveRuntimeVirtualTextureLodInfo::CullValue

Value used according to the CullMethod.

LodBias

uint16 FPrimitiveRuntimeVirtualTextureLodInfo::LodBias

Bias to use for Lod calculation in the runtime virtual texture.

MaxLod

uint16 FPrimitiveRuntimeVirtualTextureLodInfo::MaxLod

Maximum Lod for primitive in the runtime virtual texture.

MinLod

uint16 FPrimitiveRuntimeVirtualTextureLodInfo::MinLod

Minimum Lod for primitive in the runtime virtual texture.
