Re: Open 3D Mouse working with Spacenavd on Ubuntu 20.04

The more I look at the Spacenav code the more I convinced my self to make a dedicated driver for the Open 3D Mouse based on how Spacenav works. I wouldn't be afraid of a different protocol either. Here is a screenshot of my driver controller and it's options for enabling/disabling different protoco...

Re: Open 3D Mouse working with Spacenavd on Ubuntu 20.04

When there's a new packet in the /dev/hidrawN the first packet is the Report ID. If the Report Id it's 1, then the Handlers mouse2 event7 get and process that packet. The same goes for every Report Id. I got a problem with the current spacenav implementation. It is made for a single report id. A de...

Re: Open 3D Mouse working with Spacenavd on Ubuntu 20.04

Is it normal for these types of devices to only be usable inside the application and not on the desktop? Yes that is normal. Well, in the case of the driver spacenavd, take the data and send instrucction to the X11 so application like FreeCAD and Blender respond to it. spacenavd supports 2 differen...

Re: Open 3D Mouse working with Spacenavd on Ubuntu 20.04

I am making a Open 3D Mouse (Both Open Source and Open Hardware) based on Nordic nRF52 chips using HOGP (HID Over Gap Profile). That is great! Is anything public yet? Sorry I can't help with your specific questions as I run my old serial magellan plus xt on debian. I implemented the linux spaceball...

Could you share the FreeCAD file?
Sorry don't have one. Best I can do is a brep.

Re: 0.19: Why is there a ID in document object?

You are missing the point here. Just think about the case where the user duplicates a file (not using FC, just regular OS copy and paste), and then uses both in an assembly. This is a common use case, and we must support it obviously. With that in mind, what advantage does UUID have over simple int...

Re: 0.19: Why is there a ID in document object?

some little calculation wiht "average number of FreeCAD users" X "Number of FreeCAD documents created by an user" X "average number of objects created in a FreeCAD documents" will led to a very big number, how many digits are needed to hold this number, and for how many years this uniqueness will b...

Have you tested this? At what threshold is uuid a problem?

Re: Reimplementing constraint solver

... and neither gcc nor clang had a problem with it... just MSVC... :roll: Are you are actually copying a FCSSketch object in your current code? I am guessing not, so gcc and clang recognized it and didn't generate the default copy constructor, but msvc did try to generate the default copy construc...
