Detailed Description

template<typename TriangleMeshType>
class UE::Geometry::TImplicitSolidify< TriangleMeshType >

Use marching cubes to remesh a triangle mesh to a solid surface Uses fast winding number to decide what is inside vs outside

Generate()

template<typename TriangleMeshType >

const FMeshShapeGenerator & UE::Geometry::TImplicitSolidify< TriangleMeshType >::Generate ( )

inline

SetCellSizeAndExtendBounds()

template<typename TriangleMeshType >

void UE::Geometry::TImplicitSolidify< TriangleMeshType >::SetCellSizeAndExtendBounds ( FAxisAlignedBox3d  Bounds, double  ExtendBoundsIn, int  TargetOutputVoxelCount  )

inline

Set cell size to hit the target voxel count along the max dimension of the bounds

Validate()

template<typename TriangleMeshType >

bool UE::Geometry::TImplicitSolidify< TriangleMeshType >::Validate ( )

inline

Returns

true if input parameters are valid

Member Data Documentation

bSolidAtBoundaries

template<typename TriangleMeshType >

bool UE::Geometry::TImplicitSolidify< TriangleMeshType >::bSolidAtBoundaries = true

What to do if the surface extends outside the marching cubes bounds – if true, puts a solid surface at the boundary

bUseCustomBounds

template<typename TriangleMeshType >

bool UE::Geometry::TImplicitSolidify< TriangleMeshType >::bUseCustomBounds = false

Whether to use a custom bounding box instead of the input mesh bounds to define the domain to solidify

CancelF

template<typename TriangleMeshType >

TFunction<bool(void)> UE::Geometry::TImplicitSolidify< TriangleMeshType >::CancelF

Initial value:

= []()
    {
        return false;
    }

if this function returns true, we should abort calculation

CustomBounds

template<typename TriangleMeshType >

FAxisAlignedBox3d UE::Geometry::TImplicitSolidify< TriangleMeshType >::CustomBounds

Custom bounds to use, if bUseCustomBounds == true; ignored otherwise

ExtendBounds

template<typename TriangleMeshType >

double UE::Geometry::TImplicitSolidify< TriangleMeshType >::ExtendBounds = 1

How much to extend bounds considered by marching cubes outside the original surface bounds. Ignored if bUseCustomBounds == true.

MarchingCubes

template<typename TriangleMeshType >

FMarchingCubes UE::Geometry::TImplicitSolidify< TriangleMeshType >::MarchingCubes

protected

MeshCellSize

template<typename TriangleMeshType >

double UE::Geometry::TImplicitSolidify< TriangleMeshType >::MeshCellSize = 1.0

size of the cells used when meshing the output (marching cubes' cube size)

Source

SourceWinding

template<typename TriangleMeshType >

SurfaceSearchSteps

template<typename TriangleMeshType >

int UE::Geometry::TImplicitSolidify< TriangleMeshType >::SurfaceSearchSteps = 4

How many binary search steps to do when placing surface at boundary

WindingThreshold

template<typename TriangleMeshType >

double UE::Geometry::TImplicitSolidify< TriangleMeshType >::WindingThreshold = .5

Inside/outside winding number threshold
