    This method returns -1.0 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 negative side of the plane (i.e. the plane's normal points away from the ray's origin).

    Parameters:
    
    origin - the ray's origin
    
    dir - the ray's direction
    
    point - a point on the plane
    
    normal - the plane's normal
    
    epsilon - some small epsilon for when the ray is parallel to the plane
    
    Returns:
    
    the value of the parameter t in the ray equation p(t) = origin + t * dir of the intersection point, if the ray intersects the plane; -1.0 otherwise

    Test whether the given ray with the origin (originX, originY, originZ) and direction (dirX, dirY, dirZ) intersects the axis-aligned box given as its minimum corner (minX, minY, minZ) and maximum corner (maxX, maxY, maxZ), and return the values of the parameter t in the ray equation p(t) = origin + t * dir of the near and far point of intersection.
    This method returns true for a ray whose origin lies inside the axis-aligned box.
    If many boxes need to be tested against the same ray, then the RayAabIntersection class is likely more efficient.

    This test implements backface culling, that is, it will return false when the triangle is in clockwise winding order assuming a right-handed coordinate system when seen along the ray's direction, even if the ray intersects the triangle.

    originY - the y coordinate of the ray's origin

    dirX - the x coordinate of the ray's direction
    
    dirY - the y coordinate of the ray's direction
    
    dirZ - the z coordinate of the ray's direction
    
    v0X - the x coordinate of the first vertex

    Test whether the ray with the given origin and the given dir intersects the frontface of the triangle consisting of the three vertices v0, v1 and v2.
    This is an implementation of the Fast, Minimum Storage Ray/Triangle Intersection method.
    This test does not take into account the winding order of the triangle, so a ray will intersect a front-facing triangle as well as a back-facing triangle.
    
    Parameters:
    
    origin - the ray's origin
    
    dir - the ray's direction
    
    v0 - the position of the first vertex
    
    v1 - the position of the second vertex
    
    v2 - the position of the third vertex
    
    epsilon - a small epsilon when testing rays that are almost parallel to the triangle
    
    Returns:
    
    true if the given ray intersects the frontface of the triangle; false otherwise

    Determine whether the given ray with the origin (originX, originY, originZ) and direction (dirX, dirY, dirZ) intersects the frontface of the triangle consisting of the three vertices (v0X, v0Y, v0Z), (v1X, v1Y, v1Z) and (v2X, v2Y, v2Z) and return the value of the parameter t in the ray equation p(t) = origin + t * dir of the point of intersection.
    This is an implementation of the Fast, Minimum Storage Ray/Triangle Intersection method.
    This test implements backface culling, that is, it will return false when the triangle is in clockwise winding order assuming a right-handed coordinate system when seen along the ray's direction, even if the ray intersects the triangle. This is in compliance with how OpenGL handles backface culling with default frontface/backface settings.

```
    Determine whether the polygon specified by the given sequence of (x, y) coordinate pairs intersects with the ray with given origin (originX, originY, originZ) and direction (dirX, dirY, dirZ), and store the point of intersection into the given vector p.
    If the polygon intersects the ray, this method returns the index of the polygon edge intersecting the ray, that is, the index of the first vertex of the directed line segment. The second vertex is always that index + 1, modulus the number of polygon vertices.
    
    Parameters:
    
    verticesXY - the sequence of (x, y) coordinate pairs of all vertices of the polygon
    
    originX - the x coordinate of the ray's origin
    
    originY - the y coordinate of the ray's origin
    
    dirX - the x coordinate of the ray's direction
    
    dirY - the y coordinate of the ray's direction
    
    p - will hold the point of intersection
    
    Returns:
    
    the index of the first vertex of the polygon edge that intersects the ray; or -1 if the ray does not intersect the polygon
