Constructor & Destructor Documentation

FClipmapGeometry() [1/2]

FClipmapGeometry::FClipmapGeometry ( FVector  InOrigin, int  InMaxLevel, FVector  InLevel0CellSize, FIntVector  InCellsPerLevel  )

inline

Parameters

InOrigin

Clipmap origin, in absolute world space

FClipmapGeometry() [2/2]

FClipmapGeometry::FClipmapGeometry ( FVector  InOrigin, int  InMaxLevel, double  InLevel0CellSize, int  InCellsPerLevel  )

inline

Parameters

InOrigin

Clipmap origin, in absolute world space

Member Function Documentation

GetCellSize()

FVector FClipmapGeometry::GetCellSize ( int  Level ) const

inline

GetLevel()

FClipmapLevelGeometry FClipmapGeometry::GetLevel ( int  Level ) const

inline

GetRootOrigin()

FVector FClipmapGeometry::GetRootOrigin ( ) const

inline

Return the root origin of this clipmap, which is the origin of the last level. This point is guaranteed to line up with the cell grid on every level.

SnapToGrid()

static FVector FClipmapGeometry::SnapToGrid ( const FVector &  Position, const FVector &  GridCellSize  )

inlinestatic

Member Data Documentation

CellsPerLevel

FIntVector FClipmapGeometry::CellsPerLevel

Resolution of the grid on each level

Level0CellSize

FVector FClipmapGeometry::Level0CellSize

Worldspace length of each cell on the level.

MaxLevel

int FClipmapGeometry::MaxLevel

The maximum level present in this clipmap. Levels may also go below 0.

Origin

FVector FClipmapGeometry::Origin

Origin of this clipmap before snapping, so this point may not lie on the cell grid
