intersectRayPlane

Test whether the ray with given origin <code>(originX, originY, originZ)</code> and direction <code>(dirX, dirY, dirZ)</code> intersects the plane containing the given point <code>(pointX, pointY, pointZ)</code> and having the normal <code>(normalX, normalY, normalZ)</code>, and return the value of the parameter <i>t</i> in the ray equation <i>p(t) = origin + t * dir</i> of the intersection point. <p> This method returns <code>-1.0</code> if the ray does not intersect the plane, because it is either parallel to the plane or its direction points away from the plane or the ray's origin is on the <i>negative</i> side of the plane (i.e. the plane's normal points away from the ray's origin). <p> Reference: <a href="https://www.siggraph.org/education/materials/HyperGraph/raytrace/rayplane_intersection.htm">https://www.siggraph.org/</a>

@param originX the x coordinate of the ray's origin @param originY the y coordinate of the ray's origin @param originZ the z coordinate of the ray's origin @param dirX the x coordinate of the ray's direction @param dirY the y coordinate of the ray's direction @param dirZ the z coordinate of the ray's direction @param pointX the x coordinate of a point on the plane @param pointY the y coordinate of a point on the plane @param pointZ the z coordinate of a point on the plane @param normalX the x coordinate of the plane's normal @param normalY the y coordinate of the plane's normal @param normalZ the z coordinate of the plane's normal @param epsilon some small epsilon for when the ray is parallel to the plane @return the value of the parameter <i>t</i> in the ray equation <i>p(t) = origin + t * dir</i> of the intersection point, if the ray intersects the plane; <code>-1.0</code> otherwise
