After some time playing with Xirus here are some first comments, wishes and questions.
It is still difficult for me get the shape I want by dragging augmented points.
Besides from understanding what exactly happens while dragging these points, the way these points are movable in space also makes it hard to control the surface modifications.
The first thing I miss is a toolbar of course, but here are some more fundamental issues:
It should be possible to move the location and the tangent/curvature at a point etc. without having to switch between surfacepoints/augmented points. This switching between different types of control makes fast and intuitive modeling impossible for me.
There must be a UVN dragging mode for augmented point dragging. Most preferable with the option to drag a number of points simultaneously, each point according to its own direction, like you can in Tsplines.
Augmented points should have grips at both sides of the line/face that represents the direction and value of the curvature (what is the name?)
The “weight” of the controlpoints should allow numerical input too. You can collapse a number of points but cannot give them a certain value other then 0 without dragging them one by one.
I miss the option to subdivide a face in U or V direction only.
How can I join 2 ore more separate Xirus surfaces into one?
In wireframe mode my Xirus objects do not get highlighted when selected.
Wish: The option to snap or pull surface points to another surface or mesh.
Hope you can get the Xirus UI to a higher level, it has the potential to become the perfect tool for me as a shoe-last designer.
