Help:Contribute

This wiki belongs to everyone, and everyone can contribute to it.

If you have some knowledge in computer graphics you can help by adding new entries, expanding or checking those already there. Otherwise you can also help by checking style, grammar, and spelling.

Please see the page of suggested topics not yet present and the list of internally-linked to articles that do not yet exist

Style
Please avoid using subpages. Use categories instead.

Contents
As it is now, the wiki is somewhat of a mess. If you add a page, use preview before saving. Make sure it displays correctly.

Also, when copying contents from elsewhere (like Wikipedia) make sure to leave out everything that's not related to computer graphics.

Notational conventions
This wiki makes a heavy use of mathematical notation. To help readability, we ask contributors to adhere to the following conventions. (Right now the wiki is fairly small, so we could change these if we find it convenient, but please let's discuss it in the talk page before making any changes)


 * Use right handed systems. If you want to contribute but all the material you have is in a left handed system and don't know how to change it, or don't know the handedness at all, please state so clearly. Use one of the following templates or  . Surely someone will see it and modify it eventually.


 * When multiplying matrices and vectors, use column vectors, whenever possible.


 * Write:

\begin{bmatrix} 1 & 3 & 2 \\    1 & 0 & 0 \\     1 & 2 & 2  \end{bmatrix} \cdot \begin{bmatrix} 0 \\    7 \\     2  \end{bmatrix} = \begin{bmatrix} 1 \cdot 0 + 3 \cdot 7 + 2 \cdot 2 \\ 1 \cdot 0 + 0 \cdot 7 + 0 \cdot 2 \\ 1 \cdot 0 + 2 \cdot 7 + 2 \cdot 2 \end{bmatrix} = \begin{bmatrix} 25 \\    0 \\     18  \end{bmatrix} $$


 * Instead of:

\begin{bmatrix} 0 & 7 & 2\\  \end{bmatrix} \cdot \begin{bmatrix} 1 & 1 & 1 \\    3 & 0 & 2 \\     2 & 0 & 2  \end{bmatrix} = \begin{bmatrix} 0 \cdot 1 + 7 \cdot 3 + 2 \cdot 2 & 0 \cdot 1 + 7 \cdot 0 + 2 \cdot 0 & 0 \cdot 1 + 7 \cdot 2 + 2 \cdot 2 \end{bmatrix} = \begin{bmatrix} 25 & 0 & 18\\  \end{bmatrix} $$
