jfc forgot what less than or equal to is in .

\leq.

Kept trying \lte as if this was Leveldb...!

Finally writing up the math details of texture-shading .

Stand back I am building .

No Hankel transform or fast convolution magic yet but the basic algorithm and implementation using FFTs:

Really, wish GitHub would render LaTeX.

(Yes, I write a Markdown file and have a little JS bit that tangles it Knuth-like literate programming-style into stand-alone .py files and also weaves the original markdown into something more presentable by running Yapf python formatter on it. It worked well for Ebisu/Mudder, but this time without Hydrogen/Atom)

Back to writeup: derived the math of the spatial-domain approximation to the frequency-domain algorithm and fancy code, final piece of the puzzle is overlap-add.

My goal is to push out a minimal non-GDAL-reliant package that works on memory-mapped binary files and get back to Ebisu…

Took a couple weeks (& 4 years!) but pushed 1.0:
