Syntax
class FGeneralizedCylinderGenerator : public UE::Geometry::FSweepGeneratorBase
Remarks
Sweep a 2D Profile Polygon along a 3D Path.
TODO:
- a custom variant for toruses specifically (would be faster)
- Mitering cross sections support?
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
bool | bCapped | |
 |
bool | bLoop | |
 |
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. |
 |
ECapType | CapType | |
 |
FPolygon2d | CrossSection | |
 |
TArray< float > | CrossSectionTexCoord | -If FSweepGeneratorBase::bProfileCurveIsClosed == true and CrossSectionTexCoord.Num() >= CrossSection.VertexCount() + 1 then the first CrossSection.VertexCount() + 1 values will be used as U coordinates. |
 |
double | EndScale | |
 |
FFrame3d | InitialFrame | |
 |
TArray< FVector3d > | Path | |
 |
TArray< FFrame3d > | PathFrames | If PathFrames.Num == Path.Num, then PathFrames[k] is used for each step instead of the propagated InitialFrame. |
 |
TArray< FVector2d > | PathScales | If PathScales.Num == Path.Num, then PathScales[k] is applied to the CrossSection at each step (this is combined with StartScale/EndScale, but ignored if bLoop=true) |
 |
TArray< float > | PathTexCoord | -If bLoop == true and PathTexCoord.Num() >= Path.Num() + 1 then the first Path.Num() + 1 values will be used as V coordinates. |
 |
double | StartScale | 2D uniform scale of the CrossSection, interpolated along the Path (via arc length) from StartScale to EndScale |
 |
float | UnitUVInWorldCoordinates | Only relevant if bUVScaleRelativeWorld is true (see that description) |
