sdf-generator
A Unity tool to generate signed distance field volumes (as Texture3D
assets) from meshes.
How To Install
The sdf-generator package uses the scoped registry feature to import
dependent packages. Please add the following sections to the package manifest
file (Packages/manifest.json
).
To the scopedRegistries
section:
{
"name": "DSS",
"url": "https://registry.npmjs.com",
"scopes": [ "com.dss" ]
}
To the dependencies
section:
"com.dss.sdf-generator": "1.0.1"
After changes, the manifest file should look like below:
{
"scopedRegistries": [
{
"name": "DSS",
"url": "https://registry.npmjs.com",
"scopes": [ "com.dss" ]
}
],
"dependencies": {
"com.dss.sdf-generator": "1.0.1",
...
To Use
In Editor
- Select
SDF > Generator
from the Unity menu bar, the tool window will pop up. - Set the relevant options (described in the next section).
- Press
Create
and a save dialog will pop up. - Choose a location and name to save your SDF to.
Through a Script
// create a new generator instance
DSS.SDF.Generator generator = new DSS.SDF.Generator();
// set the relevant options (described in the next section)
generator.Mesh = someMeshInstance;
generator.Resolution = 32;
// ...etc...
// generate the Texture3D
// note: this can take a long time, so definitely don't do it each frame
// and probably only do it once when the application first starts
Texture3D sdf = generator.Generate();
Options
Mesh: the mesh you want to generate an SDF from.
Resolution: the resulting Texture3D
resolution (I recommend that you keep this below 64).
Submesh Index: for multi-part meshes, the index of the sub-mesh you want to use.
Padding: the padding to surround your mesh within the SDF (only set this to be non-zero if you see artifacts).
