I'm creating a Taliesin Table Lamp in Blender and showing different rendering techniques.

Blender has 2 different rendering engines, Eevee for faster (less realistic) images and Cycles for (higher quality) or photo realistic images.

Clay Rendering
This style just shows the form with simple ambient lighting.
Cycles rendering with ambient occlusion added to accentuate the shadows.

Procedural Rendering
The materials (textures and colors) are all computer generated.
Cycles Rendering with lighting.
