Class Geometry

  • All Implemented Interfaces:
    RenderObject

    public class Geometry
    extends java.lang.Object
    implements RenderObject
    This class represent a geometric object in its native object space. These object are not rendered directly, they must be instanced via Instance. This class performs all the bookkeeping needed for on-demand tesselation and acceleration structure building.
    • Constructor Detail

      • Geometry

        public Geometry​(Tesselatable tesselatable)
        Create a geometry from the specified tesselatable object. The actual renderable primitives will be generated on demand.
        Parameters:
        tesselatable - tesselation object
      • Geometry

        public Geometry​(PrimitiveList primitives)
        Create a geometry from the specified primitive aggregate. The acceleration structure for this object will be built on demand.
        Parameters:
        primitives - primitive list object

      • update

        public boolean update​(ParameterList pl,
                              SunflowAPI api)
        Description copied from interface: RenderObject
        Update this object given a list of parameters. This method is guarenteed to be called at least once on every object, but it should correctly handle empty parameter lists. This means that the object should be in a valid state from the time it is constructed. This method should also return true or false depending on whether the update was succesfull or not.
        Specified by:
        update in interface RenderObject
        Parameters:
        pl - list of parameters to read from
        api - reference to the current scene
        Returns:
        true if the update is succesfull, false otherwise
