Constructor Detail

CurvesHelper

public CurvesHelper(java.lang.String blenderVersion,
            BlenderContext blenderContext)

This constructor parses the given blender version and stores the result. Some functionalities may differ in different blender versions.

Parameters:

blenderVersion - the version read from the blend file

blenderContext - the blender context

Method Detail

toCurve

public CurvesTemporalMesh toCurve(Structure curveStructure,
                         BlenderContext blenderContext)
                           throws BlenderFileException

Throws:

BlenderFileException

transformBevel

protected com.jme3.math.Vector3f[] transformBevel(com.jme3.math.Vector3f[] bevel,
                                      com.jme3.math.Vector3f prevPos,
                                      com.jme3.math.Vector3f currPos,
                                      com.jme3.math.Vector3f nextPos)

The method transforms the bevel along the curve.

Parameters:

bevel - the bevel to be transformed

prevPos - previous curve point

currPos - current curve point (here the center of the new bevel will be set)

nextPos - next curve point

Returns:

points of transformed bevel

transformToFirstLineOfBevelPoints

protected com.jme3.math.Vector3f[] transformToFirstLineOfBevelPoints(com.jme3.math.Vector3f[] startingLinePoints,
                                                         com.jme3.math.Vector3f firstCurvePoint,
                                                         com.jme3.math.Vector3f secondCurvePoint)

This method transforms the first line of the bevel points positioning it on the first point of the curve.

Parameters:

startingLinePoints - the vbevel shape points

firstCurvePoint - the first curve's point

secondCurvePoint - the second curve's point

Returns:

points of transformed bevel
