Computer Graphics When I think of art I think of great artists of the past. Artists that have spent practically all their lives to produce visually stunning pieces of work. Artists such as Michelangelo, who spent 15 years of his life to finalize a painting on the ceiling of the St. Peter's Cathedral. When I think of art, I think of the legendary sculptures of the classical era. Artists then envisioned a final work from a block of stone. However, It is very difficult for me to consider a person...

Matrices Used In Computer Graphics.

Matrices Used In Computer Graphics Every one of us uses matrices nearly everyday in our lives and probably unaware of it. Matrices are commonly used in computers for their 3D graphics. Most of the matrices that are used are either 3x3 or 4x4 matrices and are computed by either rotation matrices or translation matrices. The matrices that are used are an array that holds numbers, commonly called a 3x3 array or 4x4 array. Or Examples of 3x3 and 4x4 matrices. The reason that matrices are used is...

3d Computer Graphics and Screw Thread

on this endeavor. This can lead to much frustration.  Don't Do It My usual answer when asked how make real screws is "Don't do it!" Draw them in 2D. AutoCAD strains itself on solids. A realistically modeled length of thread can bogs down most computers. And when it gets right down to it, a true screw thread is impossible in AutoCAD. Some CAD programs, like SolidWorks can make true threads, but still file size balloons and performance suffers. Do it In the Flat A 2D representation of a screw is...
