Detailed Description

The SoIndexedNurbsSurface class can be used to render NURBS surfaces.

It is very similar to the SoNurbsSurface class, but controlpoints can be specified using indices.

Member Function Documentation

void SoIndexedNurbsSurface::rayPick ( SoRayPickAction * action ) [virtual]

Calculates picked point based on primitives generated by subclasses.

Reimplemented from SoShape.

void SoIndexedNurbsSurface::sendPrimitive	(	SoAction *	,
		SoPrimitiveVertex *
	)

This method is part of the original SGI Inventor API, but not implemented in Coin, as it looks like a method that should probably have been private in Open Inventor.

void SoIndexedNurbsSurface::generatePrimitives ( SoAction * action ) [protected, virtual]

The method implements action behavior for shape nodes for SoCallbackAction. It is invoked from SoShape::callback(). (Subclasses should not override SoNode::callback().)

The subclass implementations uses the convenience methods SoShape::beginShape(), SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the primitives making up the shape back to the caller.

Implements SoShape.
