Rendering brains

Blender

Using hints from A Winkler’s excellent http://brainder.org and various tutorials and youtube clips at https://blender.org, I have started rendering some brains. My own first.

I found the following things useful:

• taking freesurfer reconstructions and converting to obj, which saves space as explained in this blog post

• downsampling images using a blender modifier, which gives you good control at the time of modelling

• switching to cycles renderer and thinking about materials and the sampling and light paths options a bit to get rid of noise.

• general advice on lighting from blenderguru and sardi pax, e.g. this clip
