GetUnProjectedPoint

getUnProjectedPoint(object, vector)

Returns the un-projected point of a screen-space point.

• object : object to operate on
• vector : vector

point = getUnProjectedPoint(Camera, vec3(x, y, z))

It can be used for example to pick a 3d object using the mouse position :

 function onSceneUpdate()
 
    mx = getAxis("MOUSE_X")
    my = getAxis("MOUSE_Y")	
    
    V1 = getUnProjectedPoint(Camera, vec3(mx, my, 0))
    V2 = getUnProjectedPoint(Camera, vec3(mx, my, 1))
    
    point, object = rayHit(V1, V2) -- note that rayHit only detects objects with physics enabled
    
    if point then
       rotate(object, {0, 0, -1}, 1) -- rotate the selected object
    end
 
 end
