I have tried Freeform in the last 30 minutes or so, and I have a few comments that I would like to share to stimulate some discussion, and possibly some improvement buy the developers.
Freeform is amazing under several aspects. It's spectacular and has a huge potential.
The 3D graphics are stunning and some tools (e.g. the spinning option) are just gorgeous.
Anyway, I want to list here a few things that I think are lacking for Freeform to become a truly useful 3D modeling tool.
1 switch tool activation on/off: I keep introducing unwanted modifications to my object when I am just trying to understand where the 'tool' is
2 free zoom and pan. Zoom out should be deeper and camera movements should not be relative to the object position. This is limiting and often annoying
3 I miss a sharpen tool...
4 anaglyph stereoscopic rendering (red/green glasses + SBS or line by line for polarized TVs/displays). Once you have a 3D inout device you need a 3D output
5 I keep messing up between the object and the menu items. As I sculpt my clay, the tool ends up in a menu item area and boom, the menu shows up and I enter commands that I don't want
In short, Freeform is dramatically cool but can hardly be used as a 3D building tool.
See Leopoly.com for a less cool, but more functional alternative.
