Detailed Description
Handler to transform coordinates of an attribute into a different coordinate system. Usually it will be used to transform the coordinates of an attribute into the object space coordinates of a shape to determine where the attribute is located relative to the shape. See the shadow algorithm for an example. Note that one has to derive from this class and create a transformer specialized for an attribute in order to make the transformer actually do something.Member Enumeration Documentation

| virtual ID VRS::CoordTransformer::target | ( | ) | const [virtual] |
Target of the handler is Attribute.
Implements VRS::Handler.
Reimplemented in VRS::DistantLightCoordTransformer, and VRS::PointLightCoordTransformer.
| virtual ID VRS::CoordTransformer::service | ( | ) | const [virtual] |

| Engine * | ||||
| ) | [virtual] |
Returns a new attribute, which is a copy of the given attribute, but converted into an alternate coordinate system (in fact, this transformer does nothing but copying the attribute).
Reimplemented in VRS::DistantLightCoordTransformer, and VRS::PointLightCoordTransformer.
