RenderMan
Harrier Model
As part of the Harrier Model project outlined in the Maya section, I studied reference images of Harrier aircraft. The images revealed that the base colouring of the skins surface appeared blotchy, due to the reflection effects of the painted metallic skin and variations in temperature over the aircraft.
The image below shows a section along the top of the fuselage of a Harrier.
To replicate this effect, I created a RenderMan shader. The basic structure of the shader was based around a fractal Brownian motion function. A series of colour splines mixed by the noise function helped to create the turbulent look. Displacement maps were also generated to create riveted panels.
The image below shows the RenderMan shader on the left and a square example of a displacement map on the right.
