Doodles > Acorn Risc PC 3D model

by David Thomas on

This is an accurate 3D model of an Acorn Risc PC 600 computer case. It was drawn in Blender during my current attempts to learn 3D modelling, inspired by the wonderful art of Guillaume Kurkdjian.

It was measured from the real thing down to the millimetre so it’s very accurate. But if for some reason you were compelled to try to 3D print it you’d soon find it’s not nearly realistic enough, e.g. the back of the case is just blank and the edges are too sharp.


The main use is in rendering pretty pictures like these:

Acorn Risc PC model A brighter rendering with less gloss - and no more levitation.

To get the rendering of the Acorn logo and the “Risc PC 600” type on the front panels looking super sharp I recreated them in vector format using Affinity Designer.

Acorn’s standard typeface was Bodoni and the best matching implementation of that I’ve found is Bodoni MT. However it’s not quite the same. And then when I started critiquing other versions of the Acorn logo I began driving myself nutty (Acorn joke there) and seeing other differences. In any case, it’s a pretty close approximation of the true Acorn logo.

I then turned them into the following 1024 pixel square textures for use on the model:

In some ways this is a return to my 1995 Make-A-Risc PC app:
