Hello.

I assume there is no update to the 3D Lut project by lildadou?
I tried the implementation for FastLED. First It looked working, but it doesn't make any interpolation. Also sometimes it return wrong number at all.

So e.g. if I use 16x16 cube with neutral 3D Lut (no effect):

For RGB(0,0,0) to (0,0,15) the output is (0,0,0).

For (0,0,16) it returns (0,0,1).

For (0,0,17) it returns (0,0,16).

For (0,0,18) to (0,0,33) the output is (0,0,17).

I'm still trying to understand this thing mathematically...

Hello there.

I checked the SW for Arduino and I was pretty surprised by the comment:
// loop() is avoided as even that small bit of function overhead
// has a measurable impact on this code's overall throughput.
Can you provide some more info about this? I tried to google something, but without success and I'm pretty curious about this problem.

Thank you!
