GetUnProjectedPoint

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

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
