Struct GeometryDrawState

Data container for meshes and skinned meshes rendering with minimal state caching. Used to update previous world transformation matrix for motion vectors pass and handle LOD transitions blending.

Assembly: FlaxEngine.dll

File: Engine/Renderer/DrawCall.h

Syntax

public struct GeometryDrawState

Fields

CullingId

Unique identifier of the object culling state. Assigned and managed by the occlusion culling system (IOcclusionCulling).

Declaration

public uint32 CullingId = 0

Field Value

uint32

LODTransition

The LOD transition timer. Value 255 means the end of the transition (aka no transition), value 0 means transition started. Interpolated between 0-255 to smooth transition over several frames and reduce LOD changing artifacts.

Declaration

public byte LODTransition = 255

Field Value

byte

PrevFrame

The previous frame index. In sync with Engine::FrameCount used to detect new frames and rendering gaps to reset state.

Declaration

public uint64 PrevFrame = 0

Field Value

uint64

PrevLOD

The previous frame model LOD index used. It's locked during LOD transition to cache the transition start LOD.

Declaration

public char PrevLOD = -1

Field Value

char

PrevWorld

The previous frame world transformation matrix for the given geometry instance.

Declaration

public Matrix PrevWorld = Matrix::Identity

Field Value

Matrix
