sphere

[mohamed mediouni]

Hello

i have a difficulty  of the intersection of the joystick and the small objects

the point of Joystick is defined 

gmtl::Point3f wand_pt = gmtl::makeTrans<gmtl::Point3f>(wand_matrix); 

I need to draw a sphere to simplify the intersection compared to the point>

What is the function
