Re: Explanations about DAG

Chrisb thanks. I am looking explanations about the red, blue etc circles , lines of every colour at the DAG view and so on. It has been a few years since I looked at that code, so this is all from my failing memory. The colored nodes and the column they occupy are related. Each nodes column is base...

Re: OpenCascde participating in GSoC 2021!

One point it is a pity that is that it looks like nothing is related to topological naming. I read something years ago, can't find it now, that opencascade is happy with their solution to toponaming and they have customers successfully using it. That is using the application document framework whic...

Ok. Yes it would nice to know how many tests are private vs public.

chennes wrote: Mon Mar 29, 2021 5:42 pm Oh, that's excellent, on my recent patch work I ran into a case where they told be they had 40 failing cases, but in the public test suite there was only one!
So do you think the public test suite is useless?

For anybody else, like me, that has never ran it.

Re: Space navigator axis confusion

But why is the default mode different from every other program that works with a spaceball? Out of the device itself, motion events have 6 integers. If you map these numbers to: (tx,ty,tz,rx,ry,rz) you get the unexpected behavior you observed. So by default the device is putting out numbers in a we...

So you don't get the spaceball motion page in the customize dialog? There is a 'flip y/z' checkbox.

Run each one of the faces through the bopcheck. 4 of them are invalid ... at least here.

Re: Why doesn't refine combine these faces?

I'm trying to implement the discrete version of OpenSCAD's rotate_extrude() function -- this is my test case, I'm using it because it's very easy to see when things are wrong: the vertex and face counts are low, and the volume can be calculated exactly with simple math. I don't actually care about ...

Re: Why doesn't refine combine these faces?

The solid has 7 faces. There is a 'micro face' in the center somewhere. Right, there is a zero-area face -- once removed, how do I "sew" it together? Right now if I exclude that face I get checkGeometry errors about unconnected edges. Ok. Sorry I am catching up. Yes there are other proble...

Re: Why doesn't refine combine these faces?

I'm struggling to understand why that doesn't work, when trying to use the surface refinement (technically I'm doing this in Python, so I'm calling removeSplitter() ). When I check the geometry, if I turn on the BOP option, it shows that I have self-intersections, but those are actually what I was ...
