Renderer that produces 3D textures that sample SDFs, Volumes, or fields.

When rendering a field (either float or vector), it just produces the field value as the main output.

When rendering an SDF, it produces the SDF’s assigned density in the main output. If the SDF doesn’t have a density, it will fill the interior with a density of 1 and the exterior with a density of 0. The color output uses a material if one is assigned to the SDF, or the SDF’s color if it has one, or white on the interior if it doesn’t.

When rendering a volume, it produces the density value as the main output. The color output uses the volume’s color attribute if it has one, with the density value as the alpha. If the volume doesn’t have a color attribute, it will produce 0.

The renderer defines a box-shaped area to sample and fills the 3D texture with the results of the sampling.

Enable Normal Output

Enable producing normal vectors. For each point, this will produce a vector pointing in the direction that the nearest surface point is facing. These values can be accessed using a renderSelect operator.
Enable World Pos Output

Enables the world xyz position output buffer.
Enable Object Id Output

Enable object ID output, which produces a TOP with values assigned with the injectObjectId operator for whichever shape each point is inside.
Enable Debug Output
Enable Custom Output 1
Enable Custom Output 2
Enable Normal Smoothing

Whether to smooth out surface normals by sampling at larger distances.

 Baked Baked
Normal Smoothing

How far apart to sample to calculate surface normals.
