LuciadLightspeedInterface ILspShapeDiscretizer

All Known Implementing Classes:

TLspShapeDiscretizer

public interface ILspShapeDiscretizer

Interface for a class that can discretize geometric shapes into a format that is easier to use for painters. The result of a discretization is an ALspEditable3DMesh object, that describes the shape using geometric primitives such as lines and triangles. Discretization is performed by the discretize method, and can be tweaked by the parameters defined in TLspShapeDiscretizationParameters. A TLspDiscretizationException is thrown when a given object cannot be discretized with the specified parameters.

Since:

2012.0

Method Summary

Modifier and Type	Method and Description
void	discretizeSFCT(Object aDomainObject, TLspShapeDiscretizationParameters aParameters, TLspContext aContext, ALspEditable3DMesh a3DMeshSFCT) Discretizes the given domain object, typically an ILcdShape.

Method Detail

discretizeSFCT

void discretizeSFCT(Object aDomainObject,
                    TLspShapeDiscretizationParameters aParameters,
                    TLspContext aContext,
                    ALspEditable3DMesh a3DMeshSFCT)
             throws TLspDiscretizationException

Discretizes the given domain object, typically an ILcdShape. The result of the discretization is output to an ALspEditable3DMesh. The result of this method is dependent on the contents of aParameters, which determines e.g. which parts of the shape (outline, interior) need to be discretized. Implementations of ILspShapeDiscretizer should ignore values of TLspShapeDiscretizationParameters.getMaximalEdgeLength() } smaller than or equal to 0.

Parameters:

aDomainObject - the object to be discretized

aParameters - provides parameters for the discretization

aContext - context information regarding the object

a3DMeshSFCT - receives the results of the discretization

Throws:

TLspDiscretizationException - Instances of ILspShapeDiscretizer should throw this exception when they cannot discretize the specified combination of domain object and discretization parameters.
