Field Detail

Method Detail

reset

public J3DPrimitiveIterator reset(javax.media.j3d.GeometryArray ga,
                         boolean... enableComponent)

Reset this iterator so that the subsequent call to J3DPrimitiveIterator.next() reads the first primitive in ga.

Overrides:

reset in class J3DPrimitiveIterator

Parameters:

ga - the geometry, or null to clear the previous internal reference

enableComponent - see J3DVertexAccessor.reset(GeometryArray, boolean...)

Returns:

a reference to this J3DPrimitiveIterator

reset

public J3DPrimitiveIterator reset(JOGLGeometry jg,
                         boolean... enableComponent)

similar to J3DPrimitiveIterator.reset(GeometryArray, boolean...)

Overrides:

reset in class J3DPrimitiveIterator

resetImpl

protected void resetImpl(int numStrips,
             int numEnabledStrips,
             int vertsPerStripPrim)

Common impl of reset(GeometryArray, boolean...) and reset(JOGLGeometry, boolean...).

resetImpl

protected void resetImpl(int numStrips,
             int vertsPerStripPrim)

resetImpl(int, int, int) with numEnabledStrips = numStrips.

next

public J3DPrimitiveIterator next()

read the next primitive

Overrides:

next in class J3DPrimitiveIterator

advanceToNextStrip

protected boolean advanceToNextStrip()

Advance J3DPrimitiveIterator.vertexAccessor so that the next vertex accessed will be the first one in the next enabled strip.

Strips with negative arrayCount will be skipped, supporting the JOGLGeometry strip-disabling feature.

This can only be called before starting to iterate the fisrst strip or immediately after the end of iterating a strip.

firstInStrip

protected void firstInStrip()

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

Default impl loads next J3DPrimitiveIterator.vertsPerPrim verts in order.

nextInStrip

protected abstract void nextInStrip()

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