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 viaInstance
. This class performs all the bookkeeping needed for on-demand tesselation and acceleration structure building.

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 interfaceRenderObject
- Parameters:
pl
- list of parameters to read fromapi
- reference to the current scene- Returns:
true
if the update is succesfull,false
otherwise
