Animal texture

What's this?

This is a work based on this link:

http://culturemath.ens.fr/contenu/dossiers.html#pelage

 

and the PDF file to illustrate the content:

http://culturemath.ens.fr/maths/pdf/analyse/vidiani_motifs_pelage_animaux.pdf

(link to a PDF in French about “boring” mathematic formulas).

 

Near the end of this document there is a small program written for Maple.

I tried to adapt this code to Csharp and from bi-color to RGB.

 

Finally, I can’t reproduce the skin of any animal as I think it should be. But some results give interesting patterns or textures.

Steps

Number of steps.

 

Ration Horizontal/Vertical

Aspect ratio horizontal/vertical of steps.

 

Calcul Mode

The choice of different formulas. Four modes are possible:

-Normal: the formula from the original code of the document except it works with RGB.

-Sinus: use a Sinus calculation as start point to generate more texture.

-Difference: use a subtraction (x-y) calculation as start point.

-Black & White: same as Normal but in grey levels (bi color like in the document).

 

Frequency / Distortion / Variation / Angle / Moire / Wave

These settings are used in the formula. Just play with them to see how they interact each over.

 

Cycles

Number of cycles of calculation. The more the slower.

 

Red / Green / Blue

Extra steps factor per channel.

 

 

 

The Examples:
