Examples of ca.eandb.jmist.math.SphericalCoordinates.opposite()

ca.eandb.jmist.math.SphericalCoordinates.opposite()
Returns the vector of the same length as this vector in the opposite direction. @return The vector of the same length as this vector in the oppositedirection.

    if (this.reflectance != null) {


      boolean fromFront = x.getNormal().dot(v) < 0.0;
      SphericalCoordinates out = RandomUtil.diffuse(ru, rv);
      if (!fromFront) {
        out = out.opposite();
      }


      Ray3 ray = new Ray3(x.getPosition(), out.toCartesian(x.getShadingBasis()));
      boolean toFront = ray.direction().dot(x.getNormal()) > 0.0;
