Idea for optimization #211
Comments
Sounds good. Please let me know the results of your tests. |
A variety of shapes in |
I added a screenshot above. Sounds like an interesting project. Curious where it will lead to. |
Don't know if this is relevant: https://sb-simd.common-lisp.dev |
@foretspaisibles are you planning to work on this? else I will give it a try. I haven't done optimization/profiling in lisp before but would like to give it a shot. |
I am still planning but we can try together, it's more fun! :-) What do you think? PS: Do you have opinions on what should be a proper benchmark? |
That would be great, thanks :) let me know how and where I can help.
By "proper benchmark" above, are you referring to identifying critical areas of code to profile before trying any optimization? Sorry its a naive question but I'm new to optimization and thought its better to clarify rather than remain unsure. |
Parallel programming is something we haven't touched in kons-9 yet. Threads, SIMD, etc. I suspect the lowest hanging fruit is optimizing the OpenGL calls. |
If anyone is into optimizing some CL code using SBCL declarations, I suggest trying it on the
src/plugins/isosurface.lisp
file. The marching cubes algorithm takes several seconds to generate a mesh, as can be seen by running the demos insrc/plugins/sdf.lisp
.It might be interesting to see how much this can be optimized, as SBCL has a high reputation for generating efficient code given the right declarations.
