Calculates the real curve lengths (used in practice) given the exact spline curve.

Parameters:

Defined in src/model/visualization/Plates/BendRenderer.ts:331

Parameters:

▪ getOffsets: function

Function returning distance after start / before end of subdivision at which cutline should start. If null is returned, the line will not be cut.

▸ (line: Line3, lineCutsBorder: boolean): [number, number] | null

Parameters:

Name Type
line Line3
lineCutsBorder boolean

▪ interlace: number

Number of groups into which the cutlines should be partitioned in an interlaced manner to reduce burning.

▪Default value solid: boolean= false

If true, draws a single line, otherwise a dashed one.

Returns: Line3[][]

Private _getNumberOfCutLines

▸ _getNumberOfCutLines(curvedLength: number): number

Defined in src/model/visualization/Plates/BendRenderer.ts:521

Parameters:

Name Type
curvedLength number

Private _getSteps

▸ _getSteps(numberOfSteps: number, offset: number): number[]

Defined in src/model/visualization/Plates/BendRenderer.ts:506

Divides [0,1] into numberOfSteps + 2 many steps. The first step is located at offset, the last one at 1-offset. Create two extra steps. One very close to the beginning and one very close to the end. This is used to circumvent rendering errors later on. These extra steps are ignored by getCutLines.

offset number 0

Returns: number[]
