Named after George Boole, these operations are the heart and soul of basic object transformation. The Boolean operations break down into 4 main types:
- Union-Combines two or more forms or shapes together to make a new form.
- Difference-Subtracts one or more forms from another.
- Intersect-Calculates the spatial overlap between forms and the result is the final output.
- Split-A similar operation as the intersect, this calculates the spatial overlap, but then also affects the operators. Such as splitting a cube with a sphere, the sphere “bite” taken out of the cube remains behind after the operation is complete.
These operations are critical to performing tasks such as creating holes in a solid, adding geometry together to create new geometry or simply extracting a shape by using two parent shapes. Boolean operations are really helpful when first learning how to 3D model.
