Outline. OpenSCAD uses a specialized language to describe 3D models. This description is parsed into a tree with nodes that either represent different base geometry (e.g. cube, cylinder) or operations that define how to combine child nodes (e.g. difference, intersection).

5.4.2017 · So I whittled the threads down to the CSG file posted above. On my new box: "Threaded traversal phase 1: Generating 4003 leaf geometries. Threaded traversal phase 2: Spawning 16075 threads on 8 cores". All results below are rendering that file, unless mentioned otherwise. All renders were preceded by a Flush Caches.

It would need to be re-coded to split rendering tasks between threads. Not easy, and may not even be possible with the libraries that it uses to do the actual rendering. This is the ...

Thread-drawing modules for OpenSCAD. internal=true. Indicates that an internal thread (e.g., for a nut) will be drawn. Internal threads should be "cut out" from a solid using difference (). The default (internal=false) indicates that external threads (e.g., for a bolt) will be drawn. (The clearances for internal and external threads are different.

Is there any bounty program for getting a multithreaded renderer? I'd definitely toss $100 at whoever pulls it off.

Apr 05, 2017 · So, in terms of CPU use, 1 thread at 100%, shows as 12.5% CPU usage, with pipelining, well cached threads can be seen to use 12.5% on all 8 threads. Note that the multi-threaded C code uses a non-yielding Spinlock, a tight loop waiting for the lock to be freed.

Feb 09, 2022 · OpenSCAD is a popular open-source design tool for 3D printing afficionados (and others). It’s essentially a CAD software for programmers with a minimalist UI. A simple declarative programming language defines Constructive Solid Geometry (CSG) operations like unions, intersections, differences, which can be parameterized with loops and variables.
