Sverchok Tree Generator


I tend toward making more abstract than realistic images with Blender. A while back I played with the Ivy Generator addon and so got interested in the underlying procedural algorithms for producing tree and plant structures. A lot of these techiques use L-systems and could maybe be implemented using the …

Generative Art - Updated Examples


The changes and improvements I made to the Generative Art node for Sverchok mean some of the examples from earlier blog posts need some updates.

I've include the updated examples in my generative-art-examples repo on github. These examples include the eisenxml and the json for the nodes (the json files …

Maze any Mesh in Blender

mobius maze

The grid of cells and list of links used as the data structure for 2D mazes by Jamis Buck's in his book "Mazes for Programmers" can be replaced with a mesh object where the vertices are equivalent to cells and the mesh edge connections define the cell neighbors. The maze …

Blender 3D Maze Generator

red maze blue maze

The same backtracking algorithm that produces 2D mazes can be used to produce three dimensional mazes. All that's needed is to set up the cells in the grid with an extra dimension and define the neighbors to include cells on the layers above and below the cell.

Here I've chosen …

Blender 2D Maze Generator

game wide shot

The game levels that can be produced by the Generative Art Sverchok node in Blender are lots of fun to explore but there's nothing to stop them producing overlapping paths like this:

overlaps in Steely Taws

This is because the alogrithim behind the node is based on L-systems and knows nothing about where its …

Hyperbolic Tiling in 3D

plane, sphere and hyperbolic footbal

In a previous post I explained the shape of planes, spheres, and hyperbolic planes in terms of hexagons arranged around either another hexagon (plane), a pentagon (sphere) or a heptagon (hyperbolic plane). I used a photo of a hyperbolic plane someone else had made out of paper, as the 3D …

Blender Adventures with Hyperbolic Planes

Hyperbolic Planes

If you cut out a large number of paper hexagons, you can arrange 6 hexagons around a central hexagon and form a honeycomb tiling of the plane. The plane has zero curvature. Its flat. Any triangle you draw on this plane has angles that add up to 180 …

Simple Sverchok 04 - Apply Matrix

3D T Square Fractal

This is part four of my introduction to Sverchok the parametric node geometry add-on for Blender. This post I'm sticking to my theme of copying one object to the structure (either the vertices or polygons) or another mesh. There is an awful lot more than just copying that can be …

Simple Sverchok 03 - Slope Dependent Trees

landscape with slope dependent trees

The first two posts (01, 02 ) in this gentle introduction to Sverchok covered copying objects to the centers of polygons and scaling the copied objects according to some pattern.

In this post we'll look at applying what we've learnt to planting trees across a landscape. We'll make the trees only …

Simple Sverchok 01 - Centers Polygons

final render sverchok centres polygon demo

Sverchok is an add-on for Blender. It allows you to generate geometry in Blender in a parametric way by wiring visual nodes together rather than programming in Blender python.

This is the first of hopefully a series on very simple examples of using Sverchok. I'm learning this as I blog …
