what is it?


Above is a rendering showing laser points of a client model for evaluation – as you can see the inherent translucency of the medium reveals too much of the surfaces on the back side and in-between – in a word confusing and ugly.  This problem can be further complicated since it is 3D – meaning the viewer can see additional angles that hide elements due to this visual overlapping.  The sad part is many of the additional surfaces that typically included in most 3D models have already been removed from this example.  Meaning “out of the box” these models would appear more dense (which isn’t a good thing).

Below is the solid model of the above model and now you can see the model for what it truly is.  More importantly, details that are present in the above model are now clearly visible.  This is because we see the shadows enforcing the contours of the shape we are looking at (lack of transparency helps too).  Look again at the model above and you will see how these shadows are not enforced.  Needless to say, we advised the client against this type of model for their design.


Understanding this and a host of other visual cues allows us to design in ways that complement the medium in a way that is recognizable.  We do this a number of ways through selective surface manipulation, density selection and just a sense of what works through constant practice in this medium. This is perhaps one of the single largest reasons we provide our service and expertise in collaboration with other designers to bring a practical solution to their vision.

Below is an example of a design that enhances the tonal quality needed.


One other thing that should be mentioned since we are on a bit of an educational bend is scale (size).  The design above is in a 4″ cube which allows the model to breath a bit.  If the cube was half this size it would have less points to define it because the points don’t get any closer together – and we all know what happens if they do get too close together.  However, smaller designs can work if the design complements the medium size.

That’s all for now!
