Method Detail

intersectsRay

boolean intersectsRay(double[] P0,
                      double[] P1)

Ray vs. bounding-volume intersection test.

Parameters:

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

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

Returns:

true if the ray intersects the bounding-volume.

intersection(double[], double[])

intersection

double intersection(double[] P0,
                    double[] P1)

Ray vs. bounding-volume intersection test with quantitative result.

Parameters:

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

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

Returns:

t-parameter >= 0.0 if the ray intersects the bounding-volume, number < 0.0 if no intersection exists.

intersectsRay(double[], double[])

intersectsCell

boolean intersectsCell(double[] o,
                       double[] size)

Rectangular box (AABB) vs. bounding-volume intersection test.

Parameters:

o - Coordinate of minimal cell-vertex (double[3]).

size - Box size (double[3]).

Returns:

true if intersection of the cell and the bounding-volume is non-empty.

isInside(double[])

isInside

boolean isInside(double[] point)

Point vs. bounding-volume test ("inside-test").

Parameters:

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

Returns:

true if the given point lies inside the bounding-volume.
