Boolean Shapes

This render was created mainly using Boolean and Pro Boolean.
I created standard primitive shapes and experimented with them to create various objects.
Then used the options on Boolean for the first object, Pizza Planet, like on the previous posts to subtract and join shapes together.
The other two objects, cheese and switch, were created using Pro Boolean which basically is an improved version of Boolean as it does not mess up the geometry and allows you to select several objects to quickly join and subtract.
