InstaLOD's Quad Remesh mesh operation reconstructs the mesh from scratch with the aim of producing a mesh entirely made of quads.
Like all mesh operations in InstaLOD Studio, Quad Remesh can be accessed from the dropdown menu in the Mesh Operations Settings panel. Settings for the Quad Remesh will vary depending on the chosen Mode. Click the tab for a particular mode to learn more about its settings.
Regular mode generates mesh topology with a dense, regular quad layout. This type of layout is useful when sculpting in DCC applications, numerical simulation, and isogeometric analysis.
¶ Settings
The following overviews the settings for the Regular remesh mode:
- Edge Mode: Determines the method used when calculating the length of the edge.
- Target Edge Size: Determines the length of the generated edges based on the chosen
Edge Mode. Increasing the size will increase the length of each edge. - Smooth Quad Mesh: Determines if the resulting quad mesh topology will be smoothed.
¶ Edge Mode and Target Edge Size
The following shows how the Edge Mode and Target Edge Size settings work together:
| Edge Mode | Target Edge Size |
|---|---|
| Automatic | Scales the automatically calculated target edge size. |
| Absolute | A precise value for the target edge size. |
| BoundingSphereRelative | A relative size based on the bounding sphere radius of the input mesh. |
Adaptive mode generates an adaptive quad mesh that can be used in subdivision surface workflows. This mode can rebuild triangulated or dense quad input geometry into clean, subdivision-ready quad topology.
¶ Settings
The following overviews the settings for the Adaptive remesh mode:
- Precision: Determines the level of precision used when generating the adaptive quad mesh. Increase the precision to improve the accuracy of the reconstruction.
- Automatic Quality: Determines the level of quality when generating the adpative quad mesh.
NURBS Patch mode (like Adaptive mode) generates an adaptive quad layout, and provides increased control over the reconstruction of the input mesh with parameter values to dial in the quality of the output.
¶ Settings
The following overviews the settings for the NURBS Patch (Preview) remesh mode:
- Control Points Resolution Mode: Determines the level of precision used when generating the adaptive quad mesh.
- Patch Layout Coarseness: Controls the simplification of the quad layout. Increase the value to simplify the generated quad layout.
- Maximum Tessellation Distance: Determines the level of quality when generating the adpative quad mesh. Smaller values align the resulting reconstruction closer to the original input mesh at the cost of denser topology.
- Vertex Welding: Enable to weld the vertices of the generated quad mesh.
¶ Feature Alignment
The following settings for feature alignment apply to all Quad Remesh modes:
- Feature Alignment: Controls the influence of the input mesh features (ex. principal curvature directions) on the resulting quad mesh topology.
- Sharp Feature Alignment: If the chosen angle is greater than 0, sharp features will be preserved based on the dihedral angle.
¶ Feature Preservation
These settings determine which features of the input mesh to preserve when running the operation.
- Preserve Sharp Features: Determines if the quads are aligned to sharp feature of the input mesh.
- Preserve Boundaries: Determines if the quads are aligned to input mesh boundaries.
¶ Preprocessing Dense Models
If the input mesh contains millions of polygons, it is recommended to first run an Optimize mesh operation to preprocess the data and reduce the overall polygon count before using Quad Remesh. With the polygon optimizer's various Optimize Settings, preprocessing the mesh to a threshold of around 100-500k polygons is recommended to improve the performance of the Quad Remesh operation.
