Small Blender Things

The last couple of weeks I have been working to create a distribution channel for my Blender related e-books that is better suited to the in...

I am still looking for good procedural noise to be used as the basis for bark materials. Such noise would need some anisotropy because the c...

While working on adding more functionality on voronoi nodes in OSL I was wondering if we could vary the metric in some interesting way. The...

The voronoi noise texture in Blender Cyles is rather limited: it is only based on the distance to the nearest point while many interesting p...

Everybody is thrilled because of Pixar's decision to offer a version of Renderman that is free for non-commercial use , and rightly so b...

In a previous article I showed how some hidden functionality in Blender's distributed OSL headers could be used to create all sorts of ...

The shader that is presented here basically takes as input a set of uv coordinates and produces a set of rectangles, each with their own uv ...

In an ongoing effort to search for methods that can be used to generate bark textures I devised this simple OSL shader: it takes a uv-map (f...

Chaos mosaic is a technique tht can be used to reduce the repetative appearance of tilebale images. An example is shown below. The upper rig...

A while ago I made a simple OSL shader for hexagonal tilings. Prompted by some questions on BlenderArtists I decided to create a more vers...

Playing with volumetrics I wanted to approximate the effect of the settling of suspended particles from a fluid, like what happens when you ...

Things are getting interesting now that more major players start supporting OSL. This week Pixar announced the support for OSL in Renderman...

With the new volume shading options offered by Blenders OSL implementation it is tempting to try this on the trees generated by the space tr...

In a BlenderArtists thread about ambient occlusion shaders the question was asked if OSL's ray tracing capabilities coudl be used to cr...

Some time ago I wrote about a routine to calculate the closest distance to a quadratic bezier spline and recently I reused this routine aga...

Falling snowflakes are easy enough to dimulate in Blender with a particle system but if quite a few of them might be seen fairly close up, t...

The basic idea of this shader is to scatter around wiggly lines that can be used as fibers, hairs or, like in the image below, noodles. Eac...

A while ago when I started this blog I created a simple shader for chocolate sprinkles and while I was reviewing comments I noticed that th...

In our first attempt to craft a shader that can mimic sheer fabric like lace curtains we approximated the fibers by filaments with a square...
