Struct CullParams

Namespace: ValveResourceFormat.Renderer.Buffers
Assembly: Renderer.dll

Shared constants for both cull passes.

public struct CullParams

Remarks

Matches CullParams_t, 160 bytes. Sequential .NET packing reproduces the std140 offsets, which in turn reproduce the packoffsets Source 2's own build uses (c0, c1, c3, c4, c7).

Fields

BinBatches

Output layout of each batch in the depth bin pass.

public CullBatchTriple BinBatches

Field Value

CullBatchTriple

BinEpsilon

Depth bin dilation, in key units.

public float BinEpsilon

Field Value

float

DepthBinWidth

Width of one depth bin, in depth key units. The key is octaves past the near plane, so bins linear in it are logarithmic in view depth while the shader still steps through them linearly.

public float DepthBinWidth

Field Value

float

DepthBins

Depth bin count. Read by neither shader, the depth bin dispatch is exact.

public uint DepthBins

Field Value

uint

FirstMaskForBatch0

First mask index of batch 0, always zero. Both shaders compare the dispatch's mask axis against these to find which batch they belong to, and their mask index within it.

public uint FirstMaskForBatch0

Field Value

uint

FirstMaskForBatch1

First mask index of batch 1.

public uint FirstMaskForBatch1

Field Value

uint

FirstMaskForBatch2

First mask index of batch 2.

public uint FirstMaskForBatch2

Field Value

uint

MaskCount

Total mask count across all batches. Read by neither shader; it is the dispatch size.

public uint MaskCount

Field Value

uint

NearPlane

Depth key of bin 0's near edge.

public float NearPlane

Field Value

float

TileBatches

Output layout of each batch in the tile pass.

public CullBatchTriple TileBatches

Field Value

CullBatchTriple

TileEpsilon

Hull dilation in cull space units. Tiles are tested as their center point, so this is what accounts for a tile's area. Zero here: the hulls arrive already dilated by the tile square.

public float TileEpsilon

Field Value

float

TileToCenterOffset

Offset mapping a tile index to its center in cull space.

public Vector2 TileToCenterOffset

Field Value

Vector2

TileToCenterScale

Scale mapping a tile index to its center in cull space.

public Vector2 TileToCenterScale

Field Value

Vector2

Tiles

Total tile count. Read by neither shader; present to keep the layout intact.

public uint Tiles

Field Value

uint

TilesX

Tile grid width.

public uint TilesX

Field Value

uint

TilesY

Tile grid height.

public uint TilesY

Field Value

uint
