Re: [ggt-devel] Submissions of patches for the GMTL

[Sebastian M. <seb...@gm...>]

Hi Patrick,

I've submitted the patches and some posted some questions and proposals 
in March 2011.

No I didn't check the trunk, as there was never a reply to the 
submissions (and some changes really needed discussion I think).
The patches included:
- Sphere-Sphere intersection
- double sided tri-linesegment intersection
- a fix in the lineseg-aabb intersection (which was not evaluating 
correctly for linesegments inside the box or only leaving it IIRC)
- closest point to triangle function

I also proposed changes regarding some important points:
- epsilon value clarification in setRot (which was skipping small 
rotations in case of close vectors). The epsilon value should be 
dependent on the type)
- inconsistent interfaces for intersectXXX functions that should all 
report "numhits" with a consistent type (in order to allow those values 
inside own templates)
- meta programming matrix initialization (effectively making the NxN 
matrix intialisation nested loops one SSE operation)

If you want me to, I can create patches against the trunk version and we 
might open the discussion about the remaining issues again.
I really like to see GMTL improved and made future-proof as I simply 
didn't find anything on the internet that is fast and supports all 
primitives I need.

Cheers
Sebastian

It looks to me like I was getting ready to release GMTL 0.7.0 with patches that you submitted, but I never finished the release. I have no idea what happened, but GMTL tends to be pretty far off my radar most weeks.
