Examine mode

hold 'CTRL'-key and drag mouse to zoom in and out
get applet

This Applet, placed besides the render applet on the HTML page, extends blaxxun3d's functionality towards an examine modus.

The user is able to rotate the displayed object simply with dragging the mouse into the desired direction. He can also zoom in and out by holding down the ctrl-key and dragging the mouse back and forth.

A few restrictions apply:

• The object to rotate must be wrapped in a transform node called 'ROOT'.
• The object is rotated around the global x and y axis (centered in the object's modeling center). To achieve intuitive rotations the object's view should therefore be parallel to the z axis.

Applet's parameters:

• turnspeed - controls the rotation speed
• zoomspeed - controls the zooming speed
• minDistance - contains the minimum distance between viewer and object (makes shure the user won't collide with the object)
• maxDistance - contains the maximum distance between viewer and object
• twistmode - model rotates only around y axis
