/**
|
|
* This duplicates the Blender manipulate tool.
|
|
* It supports quick access to Grab, Rotate, and Scale operations
|
|
* by typing one of the following keys: 'g', 'r', or 's'
|
|
* Those keys can be followed by an axis key to specify what axis
|
|
* to perform the transformation: x, y, z
|
|
* Then, after the operation and axis are selected, you can type in a
|
|
* number and then hit 'enter' to complete the transformation.
|
|
*
|
|
* Ctrl+Shift+D will duplicate an object
|
|
* X will delete an object
|
|
*
|
|
* ITEMS TO FINISH:
|
|
* 1) fixed scale and rotation values by holding Ctrl and dragging mouse
|
|
* BUGS:
|
|
* 1) window always needs focus from primary click when it should focus from secondary and middle mouse
|
