The script I am requesting would be of great benefit to tablet pc users lacking convenient access to a keyboard.
Essentially, blender has three primary commands for 3d viewport navigation.
Ideally the script would have a button for each and function in the following manner:
(1) Mouse click on button activates corresponding navigation command.
(2) While the mouse button is still held down, moving the cursor affects navigation.
(3) Viewport navigation ends upon mouse button release.
This is the same behavior as zbrush’s move, rotate, and scale buttons located in the transform palette.
I don’t have enough familiarity with blender scripting to know if mouse button down/up events can be linked to blender operations as event handlers. Please, volunteer any input you have as to if this could work and/or advice on creating the script.
I would be most appreciative is someone with a better understanding of blender scripting would undertake this project.
