The Guide has been put together by Milo Spisz, our most experienced 3D modeller, and he naturally makes it look easy. But the skills you really need for re-texturing are only basic/mid-level skills. Another good news is that because we are working on a relatively small area, there is no need for camera calibration. That means you can use any decent camera – most phones will do. Depending on the end-use of your project, you can use custom street-level photographs or even existing photographs. We have used custom-made photographs, taken on an SLR camera.
You will also need a 3D modelling and Image Manipulation software. We use 3D Studio Max and Photoshop as our standard tools. If you are not a commercial organisation, you can find cheaper or free alternatives. You can for example replace Photoshop with free GIMP and replace 3D Studio with similar free 3D software.
