[image] [image] Here’s a script that lets you input an implicit equation as a string and makes a level set/isosurface mesh. Isosurfacer.gh (17.8 KB) This is a version of the method given by Paul Bourke here . (in particular this tetrahedral version ), which @laurent_delrieu had already kindly s…

Very nice Daniel, thanks for the improvements, they are very welcome. Here a script identical to IsoSurface from Millipede. Millipede still very fast (10x) but output Invalid Mesh. So must be healed by mesh.Vertices.CombineIdentical(true, true); mesh.Faces.CullDegenerateFaces(); [image] Isosur…

With Millipede all the work happens upstream in the evaluate component because it forces you to give it the value of the field at every grid point as an input. This is exactly what I wanted to avoid. Here for the same function and resolution Millipede takes over 150x as long as the script posted a…

Look at my previous post I made a similar script as Millipede, suppressing the calculation and using a noise component to generate the values. Does I miss something ?

With both the examples in your file I think a bottleneck is generating and passing the huge list of all grid points and values before the isosurfacing component. It would be interesting to compare this with putting the noise generation method inside the Evaluate function, like the example in the fir…
