Inspired by my work and how metal parts are produced I created this picture showing the stages of production. The process starts with a drawing with all the measurements on it. A raw piece of metal is then lathed to its shape, first one side then the other. After that it is milled - the holes are drilled. Although there are still other processes such as polishing before the part is finished, the picture shows the main stages.
The most challenging part of the project and most interesting was creating the oily metal shader, which is completely procedural.
The drawing was created with the freestyle renderer.
