Method Detail

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..

See Also:

MicroFacet, BoundingVolume

assertAttributes

public int assertAttributes(MicroFacet mf,
                            java.lang.Object tmp,
                            int attributes)

Asserts validity of the given intersection-attributes. Resolves: MicroFacet.VALID_TANGENT, MicroFacet.VALID_TEX_COORD.

Specified by:

assertAttributes in interface IntersectionAttributes

Overrides:

assertAttributes in class DefaultSolid

Parameters:

mf - The checked intersection.

tmp - Non-mandatory object holding state-information for deferred computations.

attributes - Attribute mask (required attributes - see MicroFacet.VALID_*).

Returns:

Attributes which were not computed.

isInside

public boolean isInside(double[] point)

Point vs. solid test ("inside-test").

Specified by:

isInside in interface Solid

Overrides:

isInside in class DefaultSolid

Parameters:

point - Coordinates of the 3D point (double[3] or double[4]).

Returns:

true if the given point lies inside the solid.

setTemplate

public static int setTemplate(Template t,
                              int ord)

General-purpose registration routine. Sets all plugs, strings, etc. to the given Template.
