sphe_compute
Usage
- Starts the computation of spherene.
- Set computation settings
- Add project data (Part name, version...)
- See license information
Adjust settings and start computation.

The sphe_compute
command triggers the computation of spherene based on the defined parameters and control geometries in your project. This is where your part get processed using ADMS technology to generate the spherene geometry.
To initiate the computation of spherene, type sphe_compute
in the Rhino command line or click

Description
This command computes the spherene with the specified parameters.
density_reference_thickness
sets the reference wall thickness if no thickness field is present (Constant wall thickness). #Density Reference Thickness (DRT)Single Surface

These custom texts will be reflected in the resulting layer names after computation. - The
max_time
parameter sets a computation time constraint.
To iterate faster, you can work generating single surfaces or working in draft mode (Default) for solid surfaces. When ready to compute the production geometry for 3D printing, switch to "production" to get a higher resolution and smoother result.

Halfspaces and Labyrinths
Generates the actual geometries of the halfspaces or the two domains/labyrinths as result.
Use labyrinths as input for your CFD simulations
Printing Features
z-Thickness Factor
Scales the spherene overhangs slightly for thicker tops. This allows slicers for FFF methods to have more layers on the tops of spherenes.
Mesh Reduction
Decreases the polycount, this often results in faster slicing for additive manufacturing.
Generate Support Points
Automatically creates points where overhangs are detected.
This can be used for automatic support generation in slicing software.
Spherene soon is releasing a open sourced tool to automatically create 3MF files with painted supports for easy support generation in PrusaSlicer, Bambu Studio and Orca Slicer.
Density Reference Thickness (DRT)
- If no #Thickness Field Points are present, DRT defines the wall thickness.
- If no #Thickness Field Points are present and the #Density Field Points has only one point (Default), the volume fraction of the solid corresponds to the density value stated in the density field point.
- The higher the DRT, the less complex (Less genus) is the result.
- The lower the DRT, the more complex the surface becomes and the computation time rises.
