# Description

In many computer graphics applications, generating a complex, possibly
infinite, textures is a classical step to create visual content.

![](img/teaser.png)

The texture can be generated either from an examplar (see refs below),
or from a procedural model (*e.g.* [Perlin
noise](https://en.wikipedia.org/wiki/Perlin_noise)). In this project,
we ask you to create a 2D texture generator that outputs texture
images which are controlable by the user (either by an exampler or a
model) and seamless (we may want to generate textures with arbitrary
sizes). Obviously we will also evaluate the efficiency of the
generation (for instance for realtime usages).


Many existing works exist in computer graphics. We have just listed
important references below.  All these alternatives have pros and
cons. We ask you to have a look to this literature and to come up with
a solution to this (open) texture synthesis problem. We will evaluate
the relevance of the solution, the technical contribution you have
made and the justification of the choices leading to this solution.

Do not hesitate to interact with us during your exploration.
