Syntax
class FBaseRevolveGenerator
Remarks
FBaseRevolveGenerator is a base class for simple surface-of-revolution generators. Internally these are implemented via FSweepGenerator, but the Revolve generators provide simpler-to-use interfaces and handle some other aspects like endcapping/etc.
Revolve generators currently depend on the ability to use DynamicMesh operations to (eg) triangulate endcaps/etc, and so they are not currently FMeshShapeGenerators (this may be resolved in future)
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
bool | bFillPartialRevolveEndcaps | Whether or not to fill the open ends of a partial revolve, if possible |
 |
bool | bProfileAtMidpoint | |
 |
bool | bReverseDirection | Reverse the direction of the revolution, for non-closed revolutions |
 |
bool | bUVScaleRelativeWorld | When true, the generator attempts to scale UV's in a way that preserves scaling across different mesh results, aiming for 1.0 in UV space to be equal to UnitUVInWorldCoordinates in world space. |
 |
float | DegreeOffset | Offset for revolution degrees, eg to shift partial revolution around the revolve circle |
 |
double | DiagonalTolerance | When QuadSplitMode is ShortestDiagonal, biases one of the diagonals so that symmetric quads are split uniformly. |
 |
EProfileSweepPolygonGrouping | PolygonGroupingMode | PolygonGroupingMode controls how polygroups are assigned on the output mesh |
 |
EProfileSweepQuadSplit | QuadSplitMethod | QuadSplitMethod controls how quads are split into triangles (see enum comments) |
 |
float | RevolveDegrees | Degrees of the revolution path (eg circle for a regular revolution). Maybe clamped in some cases. |
 |
int32 | Steps | Number of discrete steps used to sample the revolution path |
 |
float | UnitUVInWorldCoordinates | Only relevant if bUVScaleRelativeWorld is true (see that description) |
 |
FVector2d | UVOffset | These values will be added to the generated UV coordinates after applying UVScale. |
 |
FVector2d | UVScale | Generated UV coordinates will be multiplied by these values. |
