Mesh Quality
From the "Mesh Quality" Group box, choose the mesh quality for the imported model, and if you wish to create LODs automatically out of the imported model:
Quality defines the density/visual quality of the mesh that Pixyz delivers. Depending if you import a native CAD model (exact geometry) or a tessellated model (mesh geometry), Pixyz will automatically perform either a tessellation or a decimation on the model, among other optimization algorithms.
From the "Quality" drop-down list, choose the quality level for the imported model, among 5 predefined presets or to choose custom parameters of Max Sag, & Sag Ratio for CAD model.
NOTE For CAD model, the function multiplies the length of the diagonal of the bounding box by the sagRatio. If the output value is above maxSag, then maxSag is used as tessellation value. Else if the output value is below maxSag, it is used as tessellation value.

|
MAXIMUM |
Use this setting if you wish to obtain a very dense and precise mesh (quality is a priority over low-density). A tessellation process is run. maximum sag = 0.1mm (Same as Pixyz Studio tessellate Relatively High quality preset) |
The imported mesh will be fully preserved: no optimization will be run. |
|
HIGH |
This is a modification of the Very High preset. Pixyz will deliver a superior quality mesh. Gives high-quality results for small objects. A tessellation process is run. maximum sag = 0.2mm Sag ratio = 0.0003 (Same as Pixyz Studio tessellate MEDIUM quality preset) |
The imported mesh will be slightly optimized through a subtle and limited decimation process, preserving smoothing (through surfacic and normal controls) and UVs. surfacic tolerance = 0.5mm lineic tolerance = 0.1mm normal tolerance = 1° (Same as Pixyz Studio decimation LOW aggressivity preset) |
|
MEDIUM |
Typically the best option to obtain a balanced mesh between quality and polygon count. A tessellation process is run. maximum sag = 0.3mm Sag ratio = 0.001 (Same as Pixyz Studio tessellate LOW quality preset) |
The imported mesh will be optimized through a controlled and efficient decimation, preserving smoothing and UVs. The resulting mesh might start showing smoothing irregularities. surfacic tolerance = 1mm normal tolerance = 8° (Same as Pixyz Studio decimation MEDIUM aggressivity preset) |
|
LOW |
Efficient setting to obtain a low-density mesh, or to process large objects while limiting polygon count. A tessellation process is run. maximum sag = 1mm Sag ratio = 0.003 |
The imported mesh will be highly optimized through a controlled and efficient decimation. The resulting mesh might show smoothing and topological irregularities. surfacic tolerance = 3mm normal tolerance = 15° (Same as Pixyz Studio decimation STRONG aggressivity preset) |
|
POOR |
Setting to obtain a very low-density mesh, or to process large objects while strongly limiting polygon count. A tessellation process is run. maximum sag = 3mm Sag ratio= 0.01 |
With this preset, the imported mesh will be strongly optimized through an aggressive decimation. The resulting mesh will show smoothing and topological irregularities, which can be suitable for LODs. surfacic tolerance = 10mm normal tolerance = 20° |
|
CUSTOM |
You can choose your own Max Sag and Sag Ratio. For that, get into Edit > Preferences > Pixyz and choose the value you need. |
N/A . Custom parameter is only available for Tessellation of CAD Model. If needed, you can use Toolbox Decimate function to custom your decimation level after importing at Maximum. |
