Nowadays Photogrammetry is starting to become a standard in the 3D industry. Aside from the fact that we need to keep up to date with the new technologies and techniques, we find many advantages of scanning objects from series of photographs that we can use in our current workflow. Here you can find a brief explanation of the the basic techniques and software skills needed to produce adequate finished and textured models that meet the requirements of our production pipeline.
In short, the process is as follows:
01 - Studio and Shooting: Creating a photography studio setup, choosing photography equipment and exploring the techniques needed to make a stable foundation for the following steps.
02 - Image Processing: Processing our images for best use into a photoscan software. Adobe Lightroom/Bridge.
03 - Model Creation: Using Agisoft Photoscan we build a high poly detailed mesh of our object. We orient our object into world space and scale it accordingly.
04 - Model Refinement: Exporting our object for fine tuning into ZBrush/Mudbox. Re-topology and Unwrapping.
05 - Texture Creation: After Unwrapping we import our model back to Agisoft Photoscan for creating a Diffuse texture with correct UV mapping. We use ZBrush/Mudbox for baking Displacement and Normal textures.
06 - Finishing Touches: A few thoughts on material creation and using our textures in 3DS Max.
