August 31, 2012 gl3n - OpenGL Maths for D | ||||
---|---|---|---|---|
| ||||
I updated gl3n today and added: * AABBs (axis aligned bounding boxes) * Planes * Frustum (this is not 100% tested yet, but seems to work) I also switched from cuteDoc to bootDoc. On my TODO-list: * the two open issues (nothing too important) * improve color support * SIMD Regarding SIMD, what's the current state? I heared from Manu that it's not fully implemented by DMD, but it should work with GDC? Anything you miss? For all who don't know what I am speaking about ;): Github: https://github.com/Dav1dde/gl3n Documentation: http://dav1dde.github.com/gl3n/ - David |

I heared from Manu that it's not fully implemented by DMD, but it should work with GDC? > That's debatable. - DMD implements 16 and 32 byte vectors (actually, it only supports 16 byte vectors anyway). - GDC implements 8, 16, and 32 byte vectors. - DMD has it's own __simd intrinsics that are not portable to other compilers. - GDC provides __builtin_* functions depending on whether the backend architecture implements them, which are also not portable to other compilers. Other than that, you can bet that the usual + - / * operators work and produce the correct code on GDC, not sure on the state of DMD... Regards -- Iain Buclaw *(p < e ? p++ : p) = (c & 0x0f) + '0'; |

Matrix constructor for building projection matrices (I have a bit of code for doing this from near/far + FOV if you want it, but there are plenty examples on google).
I've also found it useful to be able to set a given matrix column using a vector, I didn't see a function specifically for this (row-major makes it handy to have a dedicated function for this).
Nice work!

In my experience at least + - * work correctly with SIMD using DMD.
