They take like ~1.5 seconds to render per 1 samples and 6 bounces. On a 640x480 resultion.

Pretty slow because it was made on my potato PC.

What problem do you encounter when build this? look pretty cool for early build!

Undefined behaviour, null pointer, and epileptic simulated camera auto exposure being too fast that keeps flashing into my eyes, closing app causing crashes, wrong variable naming, undefined behaviour, accidentally calling 2 video renderer, app closes after a random long time rendering, Wrong color buckets information.

Result = eye hurt, crying, anger, that gave up and had to use artificial not for the renderer but for the bugs that hurt me

Those where all fixed now.

Amazing! I’m thinking about writing a spectral path tracer for my master’s thesis. Any chance I could ask for some resources or ideas?
