Mirror reflections in animation
Representing mirror reflections is a tricky business in all visual arts. Nowadays, we can use 3D software to calculate reflections. But before CG was available, any mirror reflections in animation, drawings, and paintings had to be figured out by the artist, and matching the subject with its reflection was solely the artist’s responsibility. We see […]
Why you need pi in animation
When you were studying animation, you probably thought you had no need for math. But one thing you definitely need to know about is the value known as pi, and how you can use pi in animation. Why pi? For centuries, mathematicians were obsessed with the relationship between the diameter of a circle and its […]
What is a BSP Tree? Demystifying the Rendering Process
Many 3D modeling and rendering programs utilize a Binary Space Partition tree (BSP tree) to make rendering go faster. Sometimes these programs will even have customizable settings for the BSP tree. But it’s hard to customize a BSP tree when you don’t know what it is! Let’s demystify the BSP tree with a simple explanation, and […]
