Ah i forgot one important thing We need to change tests, I would like to merge it when every single test is passing

Negrini085 commented 4 months ago

Be careful, cylinder bug was solved in CSG branch and not here

Negrini085 commented 4 months ago

Now tests should pass, but i want to highlight some things we still have to work on. We should:

[ ] Think about brdfs and maybe test it a little better
[x] Test get closest hit (maybe by some random testing??)
[ ] sceneFiles must be changed, but firstly we need to have stable code

Negrini085 commented 4 months ago

Right now ellipsoids are good, they should work. For sure we need to check sceneFiles implementation & tests

I'm kind of struggling to adapt csg to this new code, for sure we need to implement something in order to be able to compute more than one intersection with handler
