Q3View_StartPicking
function begins the process of picking in the view specified by the view
parameter, using the pick object specified by the pick
parameter. After calling Q3View_StartPicking
, you specify the model (for instance, by calling Q3Geometry_Submit
). When you have completely specified that model, you should call Q3View_EndPicking
to complete the picking operation. The renderer attached to the specified view might need to reprocess the model data, so you should always call Q3View_StartPicking
and Q3View_EndPicking
in a picking loop.Q3View_StartPicking
while picking is already occurring.
