blender-fractals's Introduction

Fractal

Generate any fractal that can be described by a Lindenmayer system.

How to install and enable an add-on (v.2.78)

Install add-on

Download this as a zip file
Go to File > User Preferences... > Add-Ons
On the Bottom, click on Install from File...
Select the zip file you want to install

Enable an add-on

Just... Find the add-on in the User Preferences somehow, and tick the checkbox

Draw a fractal

Add > Mesh > Fractal
In the "New entity properties" - toolbox you first have to specify a Lindenmayer system. A few examples are in this repository, in the directory test_grammars.
Then, just iterate away.
Be careful though, these fractals can grow exponentially, iterate away in a slow manner

A million thanks to the wonderful people of ANTLR

Who provided the parser generator I used, which made this project a thousand times easier.
Their project.

blender-fractals's Issues

Tick prediction off for probabalistic resolution

Make probabilistic non-terminal resolution work

Make rotation local

The terminal for rotation currently rotates the direction around the global Y and Z axis. I would like them to rotate locally.

Parser output even more broken now

C Visitor does not append Terminal and NonTerminal in correct order

Incompatible with 3.x versions

Hello, the add-on doesn't seem to work in current versions of Blender and I was wondering if there is any possibility of updating it or pointing me at a resource that might let me attempt it.

Output clear parser errors

Startpoint at 3D Cursor

Currently the startpoint is at (0, 0, 0). Should be wherever the 3D Cursor is.

Accept defines in define

Currently only non-terminals and terminals are allowed in define rules. Need to check for circular defines and disallow them though.

Make moving work

Currently moving and drawing are the same thing

Automatic testing for FractalGen

Multithreading

Construct several parts of the output fractal at the same time. The difficulty here is, that the start-rotation for later starting parts is not known, so there needs to be a way to rotate all nodes around a point, after they are in the 'verts' list

Add ability to generate faces

Translate critical code to C
