- The pick2 program demonstrates the use of X overlay window on top of
- a RGBA, Doublebuffered and depthbuffered OpenGL Window to do picking.
- The program accepts two optional parameters which define the number
- of polygons in the x and y directions. The default is a 10x10 grid.
-
- RIGHTMOUSE: drag the rubberband to create a picking window.
- Polygons inside the picking window will be
- highlighted in RED.
-
- MIDDLEMOUSE: clears overlays/resets grid to initial position.
-
- LEFTMOUSE: can be used to rotate the model.
-
- Esc terminates the program.
-
- The pick buffer is set to 2000 words which can pick about 600 items.
- To pick a larger region, modify the pick_buffer_size #define in pick2.c.
