# XSLT-Perlin2D
A 2D perlin noise SVG generator using XSLT 2.0 and self loathing.
Its ugly, slow, and I'm sorry for bringing it into existence.
## Build
* This was actually a huge pain to figure out which XSLT processor to use (xalan, saxon, xsltproc, etc)
* I ended up doing something gross. I used Apache Ant and Saxon9.
* To build with Saxon9 (XSLT 2.0) use ```ant``` **Recommended**
* Can also be built with XALAN (XSLT 1.0) use ```groovy build-xalan.groovy``` but its runs terribly at greater than 128x128 size
## Generated SVG
## Input XML (```perlin-svg.xml```)
```xml
256
256
1234
6
4
```
## Generated Perlin noise XML ```example-perlin.xml```
Sample of perlin noise data that is generated before transforming to SVG.
## Output SVG ```perlin.svg```
```xml
```
