Modifier and Type	Method and Description
boolean	checkFormat(javax.media.j3d.GeometryArray ga) Check if the class, storage type, and vertex format of ga is compatible with this implementation.
boolean	checkFormat(JOGLGeometry jg) similar to J3DPrimitiveIterator.checkFormat(GeometryArray)

Method Detail

firstInStrip

protected void firstInStrip()

Implementation of J3DPrimitiveIterator.J3DStripIterator.next() in the case that a new strip has just started.

Default impl loads next J3DPrimitiveIterator.vertsPerPrim verts in order.

Overrides:

firstInStrip in class J3DPrimitiveIterator.J3DStripIterator

nextInStrip

protected void nextInStrip()

Implementation of J3DPrimitiveIterator.J3DStripIterator.next() except for the case that a new strip has just started.

Specified by:

nextInStrip in class J3DPrimitiveIterator.J3DStripIterator

pick

public float pick(float[] pickStart,
         float[] pickExtent,
         float threshold,
         int cullFace)

this impl calls J3DPrimitiveIterator.pickQuad(float[], float[], float, int) directly

Overrides:

pick in class J3DPrimitiveIterator

Parameters:

pickStart - the start 3D coordinates of the pick segment in the same coordinate frame as the geometry of this iterator

pickExtent - the 3D extension vector from pickStart of the pick segment in the same coordinate frame as the geometry of this iterator

threshold - the pick threshold, or NaN for none, see above

Returns:

the signed coordinate of the intersection along the pick segment, normalized to the segment length, or NaN if no intersection

checkFormat

public boolean checkFormat(javax.media.j3d.GeometryArray ga)

Check if the class, storage type, and vertex format of ga is compatible with this implementation.

Overrides:

checkFormat in class J3DPrimitiveIterator

checkFormat

public boolean checkFormat(JOGLGeometry jg)

similar to J3DPrimitiveIterator.checkFormat(GeometryArray)

Overrides:

checkFormat in class J3DPrimitiveIterator

newInstance

protected J3DPrimitiveIterator newInstance()

make a new instance of this implementation

Overrides:

newInstance in class J3DPrimitiveIterator
