Detailed Description

PCLVisualizerInteractorStyle defines an unique, custom VTK based interactory style for PCL Visualizer applications.

Besides defining the rendering style, we also create a list of custom actions that are triggered on different keys being pressed:

p, P : switch to a point-based representation
w, W : switch to a wireframe-based representation (where available)
s, S : switch to a surface-based representation (where available)
j, J : take a .PNG snapshot of the current window view
c, C : display current camera/window parameters
f, F : fly to point mode
e, E : exit the interactor\
q, Q : stop and call VTK's TerminateApp
+ / - : increment/decrement overall point size
g, G : display scale grid (on/off)
u, U : display lookup table (on/off)
r, R [+ ALT] : reset camera [to viewpoint = {0, 0, 0} -> center_{x, y, z}]
ALT + s, S : turn stereo mode on/off
ALT + f, F : switch between maximized window mode and original size
l, L : list all available geometric and color handlers for the current actor map
ALT + 0..9 [+ CTRL] : switch between different geometric handlers (where available)
0..9 [+ CTRL] : switch between different color handlers (where available)
SHIFT + left click : select a point
