| I need to estimate the area of an object facing the camera. This is what I've come up with so far. frontarea#=50.0 Toparea#=50.0 sidearea#=50.0 totalarea#=0.0 yaw#=45.0 pitch#=0.0 roll#=0.0 totalarea#=Abs(Sin(yaw#)*sidearea#)+Abs(Cos(yaw#)*(Abs(Sin(pitch#)*toparea#)+Abs(Cos(pitch#)*frontarea#))) Print "Total: "+totalarea# WaitKey() It seems to work(although I haven't done much testing), but is there an easier or faster way of doing it? Any input would be very welcome! Andy |

| Out of habit I break calculations into smaller pup-sized chunks. I wouldn't shunt that little maggot into one super-calc. Not sure if it is quicker - however, I have convinced myself that my way is better and more efficient - frankly more dominant. |
