|
|
* Vector control *
|
|
* ---------------- *
|
|
* *
|
|
* A 3D vector MFC control derived from CButton. *
|
|
* Features: *
|
|
* - Real-time light rendering on a 3D ball. *
|
|
* - Variable ball radius and position. *
|
|
* - Supports bitmap background (tiled). *
|
|
* - Supports vertical gradient color background (from color to color). *
|
|
* - Variable ball color (diffuse), light color and ambient color. *
|
|
* - Variable specular intensity. *
|
|
* - Supports attached controls (for automatic update). *
|
|
* - Variable mouse sensitivity. *
|
|
* - Supports front clipping (vector will not have negative Z values). *
|
|
* - Supports callback functions for the following events: *
|
|
* 1. The trackball has moved (vector is changing). *
|
|
* 2. The user dropped the trackball (released left mouse button) *
|
|
* i.e., the vector was changed. *
|
|
* *
