示例1: changeGeo

{
GeometryPtr geo = GeometryPtr::dcast(node->getCore());
if(geo == NullFC)
return Action::Continue;
GeoColors3fPtr colors = GeoColors3fPtr::dcast(geo->getColors());
if(colors == NullFC)
{
colors = GeoColors3f::create();
colors->resize(geo->getPositions()->getSize());
// Change the geometry to use the new colors
beginEditCP(geo, Geometry::ColorsFieldMask);
geo->setColors(colors);
// If multi-indexed, make the colors use the same index as
// the geometry
if(geo->getMFIndexMapping()->size() > 0)
{
Int16 pind = geo->calcMappingIndex(Geometry::MapPosition);
if(pind < 0)
{
FFATAL(("Multi-indexed, but no positions index???\n"));
