示例1: changeGeo
OSG::Action::ResultE changeGeo(OSG::Node *node)
{
OSG::Geometry *geo = dynamic_cast<OSG::Geometry *>(node->getCore());
if(geo == NULL)
return OSG::Action::Continue;
OSG::GeoColor3fPropertyRefPtr col = dynamic_cast<OSG::GeoColor3fProperty *>(geo->getColors());
if(col == NULL)
{
col = OSG::GeoColor3fProperty::create();
col->resize(geo->getPositions()->getSize());
// Change the geometry to use the new colors
geo->setColors(col);
// If multi-indexed, make the colors use the same index as
// the geometry
if(geo->getIndex(OSG::Geometry::PositionsIndex) != NULL)
{
geo->setIndex(geo->getIndex(OSG::Geometry::PositionsIndex),
OSG::Geometry::ColorsIndex );
}
}
OSG::Real32 size = col->getSize();
for(OSG::UInt32 i = 0; i < size; ++i)
{
OSG::Color3f c;
c[0] = 0.0f;
c[1] = static_cast<OSG::Real32>(i) / size;
c[2] = 0.0f;
col->setValue(c, i);
}
return OSG::Action::Continue;
