To give you an idea of speed; Generating the same mesh in the same resolution directly in POV-Ray using similar code, without writing the file takes ~30 s here, on a decade old box. With writing the file it takes ~5 s more. Parsing the written ASCII file takes ~2 s. On that old box the Nim version, blush blush, takes 6 seconds. ( I see a solution in an other direction...) I'll look into the `-d:nimPreviewFloatRoundtrip` option, that's a substantial imporvement. @Stefan_Salewski Although I 'only' do 3D work I'll have a thorough poke at your project. Thanks
