Functions

Type Name Description
int32 bspBrushCSG ( ABrush* Actor, UModel* Model, UModel* TempModel, UMaterialInterface* SelectedMa..., uint32 PolyFlags, EBrushType BrushType, ECsgOper CSGOper, bool bBuildBounds, bool bMergePolys, bool bReplaceNULLMaterialRefs, bool bShowProgressBar ) Performs any CSG operation between the brush and the world.
void bspBuildFPolys ( UModel* Model, bool SurfLinks, int32 iNode, TArray< FPoly >* DestArray ) Build EdPoly list from a model's Bsp. Not transactional.
void bspCleanup ( UModel* Model ) Clean up all nodes after a CSG operation.
void bspMergeCoplanars ( UModel* Model, bool RemapLinks, bool MergeDisparateTextures )  
int32 bspNodeToFPoly ( UModel* Model, int32 iNode, FPoly* EdPoly ) Convert a Bsp node to an EdPoly. Returns number of vertices in Bsp node.
void bspOptGeom ( UModel* Model ) Optimize a level's Bsp, eliminating T-joints where possible, and building side links.
void bspRepartition ( UWorld* InWorld, int32 iNode ) Repartition Bsp tree
bool polyFindBrush ( UModel* InModel, int32 iSurf, FPoly& Poly ) Find the Brush EdPoly corresponding to a given Bsp surface.returns true if poly not available
void polyGetLinkedPolys ( ABrush* InBrush, FPoly* InPoly, TArray< FPoly >* InPolyList ) Populates a list with all polys that are linked to the specified poly.
void polyGetOuterEdgeList ( TArray< FPoly >* InPolyList, TArray< FEdge >* InEdgeList ) Takes a list of polygons and returns a list of the outside edges (edges which are not shared by other polys in the list).
void polySetAndClearPolyFlags ( UModel* Model, uint32 SetBits, uint32 ClearBits, bool SelectedOnly, bool UpdateBrush ) Sets and clears all Bsp node flags. Affects all nodes, even ones that don't really exist.
void polySplitOverlappingEdges ( TArray< FPoly >* InPolyList, TArray< FPoly >* InResult ) Takes a list of polygons and creates a new list of polys which have no overlapping edges.
void polyUpdateBrush ( UModel* Model, int32 iSurf, bool bUpdateTexCoords, bool bOnlyRefreshSurfaceMaterials ) Update the brush EdPoly corresponding to a newly-changed poly to reflect its new properties.
