boromisp ed12134f34 Fixed the original ray-sphere intersection 
Changed the original analytic method to a geometrical.

The errors in the original intersection calculation:
The function has a sphere center parameter, but ignores it and assumes
that the sphere is in the origo.
It calculates the length of the ray direction vector, but later on uses
this vector as a unit vector.
The position calculation is simply wrong. It multiplies the direction
vector with the radius of the sphere instead of the calculated
intersection distance.

The quadratic equation solving could be improved too:
There should be an early exit for negative discriminant.
The naive implementation sould be changed to a floating-point
specialized one.

boromisp 3a3c1fd8e8 Added new ray-sphere intersection 
This version uses a geometric method (usually faster) and doesn't
calculate the intersection position and normal, only the distance.

Fixed component swapping in tmat2x2::_inverse()
 2012-11-08 16:00:49 -08:00
Tim Howard e2bc911f00 Fixed component swapping in tmat2x2::_inverse(). 
NB: glm::detail::tmat2x2::_inverse() incorrectly swaps all components instead of only main diagonals:

	A = ⌈a  b⌉
	    ⌊c  d⌋

(using standard representation). _inverse() on A incorrectly gives the order

	⌈ d  -c⌉
	⌊-b   a⌋

(swaps both diagonals) where it should be

	⌈ d  -b⌉
	⌊-c   a⌋

(I am leaving out division by the determinate for clarity).

Also, glm::inverse() in `glm/core/func_matrix.inl` is correct for 2x2 matrices and shows the mistake of _inverse().
The unit tests do not appear to test division of a mat2 by a mat2 (where this could arise).
