Rotatable tileable texture

Using imagesynth I can make good tileable textures, but I see no feature there, or in other photoshop filters which make rotatable tileable textures

Hi Jakob,
I think that any object that is symmetric on both the x and y axis that you ‘Offset’ by half each way (with wraparound) will be a rotatable (at the angles you list) tile that can be used as a texture. Here is an example of a shape that has been Offset by half: http://picasaweb.google.com/ronviers/PatternProject/

And here it is tiled:

And here it is tiled while rotated:

And here are the two blended in difference mode so you can see that they pin register:

Here are those links again.

The links still did not work so you will have to copy and paste them into your browser, sorry.

I think that any object that is symmetric on both the x and y axis that you ‘Offset’ by half each way (with wraparound) will be a rotatable (at the angles you list) tile that can be used as a texture.

I agree. If they are symetric, then that will be the case, but I can not see how I make (I am new at making textures) a grass texture symetric in x and y without making it look artificial.

Thanks for the work you put into demonstrating your point though! I copy and pasted the links and they worked fine. Only, my texture is not symetric, and would probably look strange if it was..?

Grass is tough. I have tried several methods that include various combinations of rotating duplicating and flipping to get to an area that can be offset but like you say they have a very strange look to them. Because of grasses vertical nature it is easy to flip but difficult to rotate. It is a very cool problem to work on though. I will try again later, after meditation, but to be honest I hope a real PS expert will step in and show us how it’s done.

Good luck,
Ron

I tried again but I began to suspect that it may be impractical. I was able to get a rather complicated set of objects to tile easily using Illustrator but they were existing symbols and to hand draw grass or whatever would be nontrivial. Besides you did not mention that you have Illustrator. So I did some reading. I suggest you read this article.

The primary implication being that high quality textures can be generated mathematically with low cost software. The user provides the software an initial texture from which any number of seamless textures can be generated. The user then repeatedly selects from successive approximations of the desired result until a "recipe" for a texture is created and saved for later use. I have not tried it but it sounds interesting.

Good luck with your project,
Ron
