Scaling in Virtual Worlds

In this session, we’re going to talk about scaling. Scaling is one of the core concepts to consider when working with virtual worlds, so let’s begin. Scaling is a useful feature in virtual words. It can be used to resize objects from their original size to sizes that fit the context of the world or occupy space. Scaling can be applied along individual dimensions. For example, here we see a sphere scaled to three times its size along the x-axis, or along the y-axis or the z-axis.

In most situations, the object will be scaled by the same factor across all three dimensions. Scaling has one other interesting use. Scaling can be used to invert the shape of an object along any of its dimensions by using negative scale factors. In summary, virtual words and objects within them can be scaled as desired, an object can be scaled along any of its dimensions, and negative scale factors can be used to invert the shape of objects.
