Luxology ImageSynth 2.0，Photoshop 插件版本和独立版。

Luxology  ImageSynth是一款功能强大的无缝贴图生成插件,原先被集成于另一款出色的三维软件 Luxology  modo中，现在官方又推出了能独立运行于Adobe  Photoshop的插件版ImageSynth。你可以用它在Photoshop中制作出高分辨率的图像，且无需考虑原始资料分辨率，因为此插件运用了先进的图像合成运算法则.

imageSynth 2 is an advanced technology that allows you to create  seamless textures and high-resolution tiled images from low resolution  sources. It’s the ultimate organic pattern making tool for creating  infinitely tileable images — a “must have” for every artist’s digital  tool box.

Run fo-is2s.exe if you want to install standalone program and fo-is2p.exe for Adobe Photoshop plug-in.

Note: standalone version says beta4 in "about" dialog box, but  actually it's final 2.0, developers just forgot to update version info
