c6c8dd15f2 Add missing implementation of fmat4x4SIMD binary operators. 2012-12-21 08:28:34 +10:00
Dave Reid
a4ea111417 Add a new constructor to fmat4x4SIMD that takes a __m128[4]. This is used in a future commit. 2012-12-21 08:19:36 +10:00
Dave Reid
3681cd3523 Add support for doing an identity initialization in the default constructor of fmat4x4SIMD(). 
This is disabled by default and enabled with GLM_SIMD_ENABLE_DEFAULT_INIT. It makes toggling between SIMD and non-SIMD builds a bit easier.

efff3add87 Add support for doing a (0.0, 0.0, 0.0, 0.0) initialization in the default constructor of fvec4SIMD(). 
This is disabled by default, but enabled with GLM_SIMD_ENABLE_DEFAULT_INIT. This makes toggling between SIMD and non-SIMD builds a bit easier.

87c90590be Add support for x,y,z,w accessors to fvec4SIMD. 
This is done via a union. It must be enabled with GLM_SIMD_ENABLE_XYZW_UNION. A nameless struct/union warning in VC (C4201) is explicitly disabled with the "pragma warning(push/pop)" system.

Allowing xyzw access makes it much easier to toggle between SIMD and non-SIMD builds.

1683e78f58 Fixed the line-sphere intersection 
The original implementation had the same mistakes than the ray-sphere
intersection.
Added two new 'out' parameters to return both intersection ponits.
Changed the implementation to the geomethric method.

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.

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.

da530ac46e Fix integer version of glm::log2 for GCC 
This pretty much reverts the fix done in commit
1ed0e3865b

This temporarily breaks log2 for GCC in cases where GLM_FORCE_PURE
is not defined. The workaround introduced in commit
1ed0e3865b seems to rely
on getting invalid results from the nlz function.

Broken nlz is caused by a broken findMSB function for GCC.

A fix for the findMSB function should be available in a nearby
separate commit.
