Python implementation of wavelet rasterization

If anyone is interested in a beginner introduction to what wavelets are generally, and how they are used - I did a blog post a while back using numpy: <a href="http:&#x2F;&#x2F;kastnerkyle.github.io&#x2F;posts&#x2F;wavelets&#x2F;" rel="nofollow">http:&#x2F;&#x2F;kastnerkyle.github.io&#x2F;posts&#x2F;wavelets&#x2F;</a>

Wavelets were a big thing when I was at university (circa 1997). They were touted to be a giant leap in image compression along with fractals. Interesting to see people are still exploring that area of maths; much of the predicted technology never took off.

Here’s the paper, which I haven’t read yet. <a href="http:&#x2F;&#x2F;faculty.cse.tamu.edu&#x2F;schaefer&#x2F;research&#x2F;wavelet_rasterization.pdf" rel="nofollow">http:&#x2F;&#x2F;faculty.cse.tamu.edu&#x2F;schaefer&#x2F;research&#x2F;wavelet_raster...</a><p>There’s a large literature of rasterization techniques. Does anyone have insight into when this one would be useful?<p>Here are some other recent papers:<p><a href="http:&#x2F;&#x2F;research.microsoft.com&#x2F;en-us&#x2F;um&#x2F;people&#x2F;cloop&#x2F;LoopBlinn05.pdf" rel="nofollow">http:&#x2F;&#x2F;research.microsoft.com&#x2F;en-us&#x2F;um&#x2F;people&#x2F;cloop&#x2F;LoopBlin...</a> <a href="http:&#x2F;&#x2F;http.developer.nvidia.com&#x2F;GPUGems3&#x2F;gpugems3_ch25.html" rel="nofollow">http:&#x2F;&#x2F;http.developer.nvidia.com&#x2F;GPUGems3&#x2F;gpugems3_ch25.html</a><p><a href="http:&#x2F;&#x2F;w3.impa.br&#x2F;~diego&#x2F;projects&#x2F;GanEtAl14&#x2F;" rel="nofollow">http:&#x2F;&#x2F;w3.impa.br&#x2F;~diego&#x2F;projects&#x2F;GanEtAl14&#x2F;</a><p><a href="https:&#x2F;&#x2F;developer.nvidia.com&#x2F;gpu-accelerated-path-rendering" rel="nofollow">https:&#x2F;&#x2F;developer.nvidia.com&#x2F;gpu-accelerated-path-rendering</a>

Apparently this technique calculates the <i>exact</i> pixel values from box filtering the &quot;infinite&quot; resolution polygons. I wonder if the same technique can be applied for circular or elliptical arcs.<p>What are the most common rasterizer algorithms currently in use by vectorgraphics software? I mean pdf readers, postscript renderers, font renderers, etc...

Why does Python code always look like assembly code? Is this just laziness on the coder&#x27;s part or is Python inherently unreadable?

This looks like a perfect thing to try various python optimisations&#x2F;optimisers on - numba, pypy, cython and shedskin to name 4.
