Planned to support Swept Mode for Bezier curves/Line segments to create surface patches (probably the most expensive primitive).

You can change the width and the offset of midpoint at each control point.

You may need to manually avoid extreme twisting to reduce self intersections and cracks.

Another very important progress is the High Quality Bezier Curve.

The previous implementation is based on iq's analytic Bezier sdf implementation, which is not numerical robust and has artifacts in certain cases. So, I switched to a numerical solution to achieve better quality of Bezier curves and patches. It may have some performance loss, but I think it's worthy. I'm glad that all the issues with Tapered Bezier are solved now.

Pretty damn cool! Most expensive primitives are also most versatile 🤩

It's great that we have some degree of control over the bezier curve at each sweep point! Will this work with P4 beziers? and 3D beziers (probably not)?

the swept volume is only applied on 2d profile shape. p4 requires different control and has some other limitation due to the increased complexity.

nice and useful for designing shell structures. if you could provide an interactive preview with incremental snapping showing dimensions and angles while editing, the software would feel more precise. In this way, it can be more beneficial for industrial designers, interior designers and architects. Let me know if this is already possible... PS: I am still begging for the MacOS version.

Perhaps this can be implemented as a button that takes us into the precise design mode.

Hi, sorry for the long post but I tried to google for these answers but couldn't find anything When I open the program it runs in windowed mode, so when I go full screen the viewport doesn't scale to 4K. The UI does, but the model and the checkered bg stays pixelated, how do I change the resolution? I checked the config files and I can only see the UI scale in the text file. This isn't related to the voxel resolution (I did tried to click on increase/decrease resolution), the program looks very crisp in windowed mode otherwise but it's around 1080p so when I maximize the window it stays blurry. Another thing I don't know if you've noticed, but when used with a Wacom tablet it doesn't recognize right click from the pen by default (drivers up to date). I changed the per software settings in the Wacom to force right click with the pen for this app, but MagicCSG still doesn't recognizes it. If I'm not forgetting anything, it might have something to do with the Windows Tablet implementation And lastly I tried to change the hotkeys in the .txt file for drag left mouse button to solve that issue, typing for example: // drag left mouse button 'zoom' : { 'Shift' 'ctrl'} But the hotkeys aren't recognized, I then later tried with a single key/button in combination with dragging the left mouse button but the hotkey doesn't appear to be updating the settings in the launcher at all, Pan Zoom and Focus are still on their default keys even after changing and saving the Hotkey.txt file. Is there anything I should be doing?

I don't think it's possible yet to change the navigation controls. You can hold the 'Z' key while dragging your pen to zoom in or out. I've gotten sufficiently used to that when switching from / to other editors. Regarding recognition of right-click via a Wacom pen button: I've got no issues with that. You might try resetting your Wacom settings, then try the custom settings again. Sometimes that helps. I've solved pen customization issues with ZBrush that way.
