Modifier and Type	Method and Description
double[]	getModelTranslation(double[] uvw, ViewPort viewPort) Returns Model translation from screen translation.
double[]	getScreenTranslation(double[] xyz, ViewPort viewPort) Returns Screen translation from model translation.

Method Detail

getModelTranslation

double[] getModelTranslation(double[] uvw,
                           ViewPort viewPort)

Returns Model translation from screen translation. An array of length 3: xyz[] = model(uvw[]). For 2D systems the 3rd coordinate may be ignored. The returned array may have a lifetime up to the next call to this method on this object.

getScreenTranslation

double[] getScreenTranslation(double[] xyz,
                            ViewPort viewPort)

Returns Screen translation from model translation. An array of length 3: uvw[] = model(xyz[]). For 2D systems the 3rd coordinate may be ignored. The returned array may have a lifetime up to the next call to this method on this object.
