4. Logarithmic spiral

A logarithmic spiral, equiangular spiral, or growth spiral is a self-similar spiral curve that often appears in nature. The first to describe a logarithmic spiral was Albrecht Dürer (1525) who called it an "eternal line" ("ewige lini").[1] More than a century later, the curve was discussed by Descartes (1638), and later extensively investigated by Jacob Bernoulli, who called it Spira mirabilis, "the marvelous spiral".

The logarithmic spiral can be distinguished from the Archimedean spiral by the fact that the distances between the turnings of a logarithmic spiral increase in geometric progression, while in an Archimedean spiral these distances are constant..

5. Geometric progression

In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2..

11. Perspective Projection of a Rectangle (Homography)

Short study of the perspective projection of a rectangle in space; homography opposed to bilinear transform.

12. Learning Basic Math Used In 3D Graphics Engines

Math explanation and game engine coding. This article will help you to understand the 3D math used in 3D engines, by removing the GPU layer abstraction and using only the CPU. And to make a 3D engine based on voxels. This article was possible with my wish to see a game with texture and object built only with voxel.
