Re: [Chicken-users] new egg: glm
Hi guys, I decided to use a MIT license like Dan suggested. It's what GLM uses, and it will probably make life easier if at some point we want to embed the GLM sources into this egg (GLM is a header-only implementation). It should be fairly stable now and hopefully usable, but please help me test! I've tagged version 1.0 and made a release-info file: https://github.com/Adellica/chicken-glm/raw/master/glm.release-info I'd be glad to see this in the official egg-index! Thanks, K.

[Chicken-users] new egg: glm
Dear Chickeners! In my OpenGL and physics-simulation adventures I have fequently come across the need for a small math library in Chicken. I spent some time looking at the eggs out there, but some of them seemed a little overkill for my needs, so I decided to roll my own. I was looking for: - binary compatible with C/OpenGL/GLSL data-storage (f32vectors and friends) - simple to use and short naming/syntax - can multiply/add etc vector/matrix - includes some transformation helpers like translate, rotate and scale - not a lot of dependencies In C++ land, it seems like GLM math library is popular, and it matches the criteria above (except language). A few days in, I've got a fairly functional math util egg: https://github.com/Adellica/chicken-glm Feedback is very welcome! In particular, because of all the different types (vec2, vec3, ivec2 etc), I wrote a template macro which does basic substring substitution: (template `((D 2 3 4)) (define (make-vecD fill) (make-f32vector D fill)) (define (make-dvecD fill) (make-f64vector D fill)) (define (make-ivecD fill) (make-s32vector D fill)) (define (make-uvecD fill) (make-u32vector D fill)) (define (make-bvecD fill) (make-u8vector D fill))) That will expand the body three times, each time substituting D with 2~4. This works quite nicely and saves me a lot of copy-paste, but I don't know if it's in the Scheme spirit. Any thoughts? Vectors use structures from srfi-4, and matrices get their own record (storing column-count along with its srfi-4 vector). Once chicken-glm stabelizes a little, I'd like to make it reachable from chicken-install.

Re: [Chicken-users] new egg: glm
Wild! I've looked at binding GLM a few times but shied away from the wall of templates. Your solution is a rather elegant hack, IMHO, leaving little to the clients of your bindings to fuss about. What's the license? -Dan ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
Re: [Chicken-users] new egg: glm
I'm glad to hear, I hope this will come in handy. I'll license it with whatever fits the Chicken model and community. Is that BSD perhaps? It still needs a bit of work though, let me know if there are any feature requests and I'll see what I can do. K. On Apr 15, 2013 7:14 PM, Dan Leslie d...@ironoxide.ca wrote: Wild!
