extrudeContourStepsScaled

fun extrudeContourStepsScaled(contour: ShapeContour, path: Path3D, stepCount: Int, up0: Vector3, contourDistanceTolerance: Double = 0.5, pathDistanceTolerance: Double = 0.5, steps: List<Vector3> = path.equidistantPositions( stepCount, pathDistanceTolerance ), frames: List<Matrix44> = steps.frames(up0), startCap: Boolean = true, endCap: Boolean = true, scale: (Double) -> Double = { _ -> 1.0 }, writer: VertexWriter)(source)

Extrude a contour along a path specifying the number of steps. The scale argument can be used to make variable width shapes. For example scale = { t: Double -> 0.5 - 0.5 * cos(t * 2 * PI) } produces an extruded shape that begins and ends with hairline thickness.

Parameters

contour

the cross-section of the mesh

path

the 3D path

stepCount

the number of steps along the path

up0

the initial up-vector

contourDistanceTolerance

precision for calculating steps along contour. Lower tolerance results in higher precision.

pathDistanceTolerance

precision for calculating steps along path. Lower tolerance results in higher precision.

steps

the resulting positions in the path

frames

a list of matrices holding the transformation matrices along the path

startCap

adds a start cap if set to true

endCap

adds an end cap if set to true

scale

A function that takes a curve t value and returns a scaling factor for contour at that point.

writer

the vertex writer function
