# Nomad 3D Editor
## Features
*TODO*
* Axes
* Modification
* Calibration
* Link to Nomad
* Material modification
* Model
* Regroup components
* Subdivide component
* Remove components
* Configurations
* Add current configuration
* Add special configurations from axes values : median, min, max
* Remove configurations
* Analyze configurations : if the median/min/max configurations and the axes are defined, computes the median/min/max values for all axes based on these configurations
* Toggle components visibility in configurations
## Interface

2. Hierarchical view of the components of the model
3. Menu bar
### Mouse
The components can be manually moved around their axis by pressing them with mouse left and dragging the mouse.
The camera is controlled by the mouse :
* Middle click + drag : rotate around the point of reference
* Right click + drag : translate in the view plane
* Scroll up : zoom in
* Scroll down : zoom out
* Control down : increase the sensitivity of translation and zoom
* Shift down : decrease the sensitivity of translation and zoom

## Material

### Material
The visual properties of a Nomad 3D model are stored as [Phong materials](https://en.wikipedia.org/wiki/Phong_shading), one for each component. However the viewer uses [Physically based Rendering (PBR)](https://www.marmoset.co/posts/basic-theory-of-physically-based-rendering/) to get a more realistic result. The conversion between the two illumination models is not usual so a simple and arbitrary conversion is applied :

* $`pbr.roughness = 1 - cap \left( \frac{phong.shininess}{maxShininess}, 0, 1 \right) `$, where $`maxShininess = 250`$.
The Phong diffuse color defines the base color of the object. The specular color (which is usually a shade of gray) defines the metalness of the object : white for metallic components, black for non-metal ones. The shininess defines the roughness of the object : the more it is shiny the less it is rough (with an arbitrary maximum shininess).
