java.lang.Object
- org.sunflow.core.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.

```
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
