Public Attributes
bool	m_bInUse = false
bool	m_bDirty = true
ezUInt16	m_uiCellsPerSide = 128
	Number of rendered quads per side (= resolution enum value).
ezTransform	m_GlobalTransform = ezTransform::MakeIdentity()
ezGALBufferHandle	m_hBakedHeights
	Persistent, bound as UAV in heights CS and SRV in VS.
ezGALBufferHandle	m_hBakedNormals
	Persistent, bound as UAV in normals CS and SRV in VS.
ezGALBufferHandle	m_hCellMaterials
	Per-cell top-3 material indices (uint/cell), baked by Step3 CS. SRV in VS.
ezGALBufferHandle	m_hVertexWeights
	Per-vertex f16 blend weights relative to cell top-3 (uint/vertex), baked by Step3 CS. SRV in VS.
ezUInt8	m_uiDefaultMaterialIndex = 0
ezImageDataResourceHandle	m_hHeightImage
	Optional greyscale image used as baseline height source; sampled each bake.
ezVec2	m_vImageOffset = ezVec2::MakeZero()
	UV offset into m_hHeightImage; selects the top-left corner of the sampled rect.
ezVec2	m_vImageSize = ezVec2(1.0f)
	UV extent of the sampled rect within m_hHeightImage. Values < 1 select a sub-region.
float	m_fHeightScale = 0.0f
	Multiplier applied to the [0, 1] greyscale sample to produce a world-space height.
float	m_fGridSpacing = 1.0f
ezTagSet	m_Tags
ezUInt64	m_uiBrushOverlapHash = 0

Detailed Description

CPU-side state for one heightfield patch managed by ezTerrainSystem.

Member Data Documentation

m_Tags

ezTagSet ezTerrainData_Heightfield::m_Tags

Identity tags for this heightfield; matched against brush include-tag filters.

m_uiBrushOverlapHash

ezUInt64 ezTerrainData_Heightfield::m_uiBrushOverlapHash = 0

Hash of the indices of brushes that spatially overlap this heightfield. Updated each time brush state is re-evaluated; compared against the previous value to skip re-bakes when the set of relevant brushes (and whether any are present) has not changed.
