| PARAMETERS |
| Object Scaling Factor Range : 0 to 999 The point on the object’s surface being shaded is used as the location to render from, sending a ray into the scene to retrieve the pixel colour at that point. This is rather like having the object “project” into the scene to sample a part of it, but in general this means you won’t get to see very much of the scene at all (see pic below). |
| This image shows how the object camera “projects” into the scene, where the Object Scaling Factor is set to 1, for a plane. The actual render will be of where the red project lines intercept the landscape - in other words, you won’t see very much of the scene at all! |
| This parameter lets you scale a “virtual” version of the object, so that you can set the desired view of the scene. Note that although this works well with planes, it has more unusual effects with other objects, since it scales in the x, y and z, from the object’s centre. This means that with a sphere, for example, points will be scaled out from the centre of the sphere, making the “virtual” version of the object larger, and potentially moving some of the points on the objects surface inside or through objects that you wish to render. |
| This image illustrates the effect of the “Object Scaling Factor” being set to greater than 1 - the plane is magnified to give a virtual copy of itself, and the rays are project out from that (note for non-planar objects, the scaling happens in the x, y and z, which can result in the points being rendered from moving “into” other objects etc). |
