G3DCoordinateSystemLogicalToLayerCoordinatesAndDirection Method |
Converts logical coordinates along an isoline to layer coordinates and the appropriate derivative.
Namespace: Altaxo.Graph.Graph3DAssembly: AltaxoBase (in AltaxoBase.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax public abstract bool LogicalToLayerCoordinatesAndDirection(
Logical3D r0,
Logical3D r1,
double t,
out PointD3D position,
out VectorD3D direction
)
Parameters
- r0 Logical3D
- Logical position of starting point of the isoline.
- r1 Logical3D
- Logical position of end point of the isoline.
- t Double
- Parameter between 0 and 1 that determines the point on the isoline.
A value of 0 denotes the starting point of the isoline, a value of 1 the end point. The logical
coordinates are linear interpolated between starting point and end point.
- position PointD3D
- Layer coordinate of the isoline point.
- direction VectorD3D
- Derivative of layer coordinate with respect to parameter t at the point position.
Return Value
BooleanTrue if the conversion was sucessfull, otherwise false.
