#booleans

One of the sub tools/sub-palettes I’ve looked into in order to research for this blog post was Live Boolean. These are one of many tools that you’re greeted within the program but there’s no direct explanation as to what it really does.

Live Boolean, for lack of a better word, is a feature in Zbrush that enables a real-time preview of how boolean operations look through sub tools.

If you’re like me, however. Booleans weren’t much of a concern to understand or comprehend if you’re a person who isn’t well averse to character modeling or just modeling in Zbrush as a whole. And looking up what Booleans are and what they do exactly is more difficult than it seems, given you’re only provided with videos on how to use them, but they’re not necessarily explained what they are exactly.

Booleans essentially allow you to add, subtract and intersect two different sub-tools together in order to make new shapes or objects without much issue. This sub-tool is relevant to not only make modeling more convenient, but utilized for practical use, such as Jewelry Design, and 3D Printing to name a few.

For basic setup, you’d load your geometry into Zbrush, and then in sub tools, you can append an object in the same world space. You don’t have to Extract any object, given it’s in its own layer. After that, you can turn on Live Boolean in order to see the general preview of how this subtool can work. Make sure to mark the geometry that’s going to be the main focus of the boolean as Start. This marks that this object is going to be of importance.

A lot of where you’re going to focus on is the sub tool channel itself. There’s not direct inclination as to where you can tweak your results at first but it’s marked by symbols on each object that's of world space.

It's also important to note, in terms of adding, in live boolean mode, though it may not look like much. Once we finally finalize our boolean what this does exactly is "merge" our two objects together so for example, if we were to boot this up to create a 3D Print of this object, it makes the process easier given that the data provided won't mistake our merged boolean as two separate objects within the printing process which would cause issues down the line.

In order to finalize/Execute our Boolean, we’d have to go under Boolean tab in sub tools, and click Make Boolean Mesh. This does not make direct changes to our current object in world space, but it creates an entirely new object in the Tools section up top.

Booleans are a data type in Python used to represent either True or False. They are commonly used in conditions and control statements such as if statements, to control the flow of the program. Here are a few examples to demonstrate the usage of Booleans in Python: # Example 1: Checking equality a = 5 b = 6 result = a == b print(result) # Output: False # Example 2: Evaluating conditions x =…
