ok here is my code. It doesn't seem to work, I meant to plot a 3d point using the Wiki's last and simple way of plotting.

This is the page again. It's the last formula the "simple version" http://en.wikipedia.org/wiki/3D_projection

Function point_3d(cam_x#,cam_y#,x3d#,y3d#,z3d#)
Local distance_x#=cam_x-x3d
Local distance_y#=cam_y-y3d
Local eye_distance#=distance_x/distance_y
Local final_x#= x3d- ((distance_x/(z3d+eye_distance)) * x3d)
Local final_y#= y3d- ((distance_y/(z3d+eye_distance)) * y3d)
SetColor 255,255,255
DrawOval final_x-1,final_y-1,2,2	
End Function

Have I made a mistake while translating it into code?
