Documentation

Performer CAVE Picking and Moving class. This class lets you pick and move objects in a Performer CAVE program. When adding objects to your performer scene graph you need to place them under a DCS (or a pfNetDCS (see netdcs module directory). Then you need to select an intersection mask for the DCS. The intersection mask allows you to isolate classes of objects that are pickable.

Once that's done you can create the CAVERN_perfCAVEPickNMove_c class (see constructor). Call the process() member function in your CAVE main loop to do the picking and moving.

See the demo program for an example.

CAVERN_perfCAVEPickNMove_c(pfScene* theScene, uint mask, int button )
Constructor for picking object
Parameters:
theScene - the performer pfScene.
mask - the Performer intersection mask to use.
button - the CAVE wand button to use for selection. 1=left, 2=middle, 3=right.

pfDCS* process()
Perform the check for button presses and picking and moving
Returns:
Returns the DCS of the object being picked and moved.

void setIncludeBackFace(int val)
Determine if you want backface polygons to be pickable
Parameters:
val - set to 1 for yes and 0 for no. Default is yes.

This class has no child classes.
