Constructor Detail

BrepSolid

public BrepSolid()

Implicit (plug) B-rep database.

BrepSolid

public BrepSolid(Brep data,
                 int solid)

Explicit B-rep database, one (or all) solids.

Parameters:

data - Explicitly defined B-rep database.

solid - Either one solid id or Brep.NULL for the whole database.

BrepSolid

public BrepSolid(Brep data,
                 java.util.BitSet set)

Explicit B-rep database, arbitrary solid set.

Parameters:

data - Explicitly defined B-rep database.

set - Arbitrary solid-set (can be null).

Method Detail

addSolid

public void addSolid(int solid)

Inserts another solid id.

assertBrep

protected boolean assertBrep()

Asserts the scene object, returns true if failed.

intersection

public java.util.List<MicroFacet> intersection(double[] P0,
                                               double[] P1)

Computes intersection of the solid with the given ray.

Parameters:

P0 - Ray origin (double[3] or double[4]).

P1 - Direction vector of the ray (double[3] or double[4]).

Returns:

List of intersection points (MicroFacets) sorted by t (parametric distance from P0). null is returned in case of bad arguments or if no intersection exists..
