As easy as X, Y, Z
- When we work in 3D software, we digitally represent the natural world, which can be measured along three dimensions. We have left and right, up and down, and back and forth. These three dimensions are called axes and are usually defined as X, Y, and Z. We use these axes as a way of measuring and navigating our virtual 3D world. These axes can be used to measure the position of objects, the size of objects, or they can measure the distance between objects. Imagine a city with tall buildings. The grid of the city represents two of the three axes. Any intersection in the city could be described via two numbers. For example, we could go to the building at the corner of third and fourth. The floors of this building would be considered the third axis in our 3D world. So, a coordinate of three, four, five could be seen as the fifth floor of the building at the intersection of third and fourth. In a 3D application, this same…
