Grid to Mesh
Generate a mesh on the surface of a volume grid.
| Entry | What it does |
|---|---|
| Inputs | Grid: Standard grid input. · Threshold: Values larger than the threshold are inside the generated mesh. · Adaptivity: The input radius |
| Output | Mesh: The generated mesh. |
Volume to Mesh
The Volume to Mesh node generates a mesh on the “surface” of a volume. The surface is defined by a threshold value. All voxels with a larger value than the threshold are considered to be outside.
Note that currently this node only works on volumes generated using geometry nodes.
Inputs
Volume
Standard geometry input.
Resolution
Base the voxel resolution at the gridsize, the amount or the size of the point cloud.
| Entry | What it does |
|---|---|
| Threshold | The voxel amount to use. |
| Adaptivity | The input radius. |
Output
Mesh
The generated mesh.
SDF Grid Boolean
Bool multiple sdf grids with each other.
| Entry | What it does |
|---|---|
| Inputs | Grid 1: The first input grid. · Grid 2: The second input grid |
| Properties | Operation: The bool method. |
| Output | Grid: The generated grid. |
SDF Grid Fillet
Round off concave internal corners in a signed distance field. Only affects areas with negataive principal curvature. This creates smoother transitions between surfaces.
| Entry | What it does |
|---|---|
| Inputs | Grid: The input grid. · Iterations: How often to run the algorithm. |
| Output | Grid: The generated grid. |
SDF Grid Laplacian
Apply laplacian flow smoothing to a signed distance field.
| Entry | What it does |
|---|---|
| Inputs | Grid: The input grid. · Iterations: How often to run the algorithm. |
| Output | Grid: The generated grid. |
SDF Grid Mean
Apply lmean (box) filter smoothing to a signed distance field. Fast separable averaging filter for general smoothing of the distance field.
| Entry | What it does |
|---|---|
| Inputs | Grid: The input grid. · Width: Filter kernel radius in voxel. · Iterations: How often to run the algorithm. |
| Output | Grid: The generated grid. |
SDF Grid Mean
Apply mean filter smoothing to a signed distance field. Evolves the surface based on its mean curvature. This smooths high curvature regions more than flat areas.
| Entry | What it does |
|---|---|
| Inputs | Grid: The input grid. · Iterations: How often to run the algorithm. |
| Output | Grid: The generated grid. |
SDF Grid Median
Apply median filter smoothing to a signed distance field. Reduces nioise while preserving sharp features and edges in the distance field.
| Entry | What it does |
|---|---|
| Inputs | Grid: The input grid. · Width: Filter kernel radius in voxel. · Iterations: How often to run the algorithm. |
| Output | Grid: The generated grid. |
SDF Grid Offset
Offset a signed distance field surface by a world space distance. It dilates or erodes while maintaining the signed distance property.
| Entry | What it does |
|---|---|
| Inputs | Grid: The input grid. · Distance: Object space distance to offset the sdf surface. |
| Output | Grid: The generated grid. |
