                                int arraySize,
                                int aDim)

public void init()

Description copied from class: PsObject

If instance has missing name then assign default name 'object_NUMBER' where number is the total number of already created instances.

leftMultMatrix

                           PgFrame aFrame)

blend

public boolean blend(double s,
                     PgFrame a,
                     double t,
                     PgFrame b)

parallelTranslate

public void parallelTranslate(PgFrame oldFrame,
                              PgFrame vertexFrame,
                              PdVector newVertex,
                              PdVector newEdge)

Parallel translate a frame along a polygonal curve in R^3. The vertexFrame is the resulting frame at the given vertex. This frame object is used to store a frame at the current vertex whose e1 direction is parallel to the newEdge, i.e. this frame can be used as the oldFrame for another call of this method to compute the frame at the next vertex.

Parameters:

oldFrame - frame at previous vertex with e1 parallel to previous edge.

vertexFrame - frame at current vertex, this is the actual result.

this - frame at current vertex with e1 parallel to new edge.

newVertex - current vertex where to compute the frame.

newEdge - edge outgoing from current vertex.
