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

The editor interface is composed of 3 parts :

1. 3D view of the model of the instrument
2. Hierarchical view of the components of the model
3. Menu bar

Nomad 3D file format

See the converter wiki.

Workflow

Axes

TODO : modify -> calibrate -> link

Model

TODO : regroup, subdivide, clean

Configurations

TODO : advices about config management : only median/min/max eventually, hide duplicates, etc

Material

The visual properties of a Nomad 3D model are stored as Phong materials, one for each component. However the viewer uses Physically based Rendering (PBR) 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.color = phong.diffuse
pbr.metalness = cap(length(phong.specular), 0, 1)
pbr.roughness = 1 - cap(phong.shininess / maxShininess, 0, 1)

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).
