May 2019 – Nick Stevens Graphics

So, in part 1 I showed you how to locate and work with references.

Here in part 2, I’m going to work an example, the Mercury Atlas. I’ve done it in one long part again so it’s easy to print. (Handy hint! You may be able to print to PDF to get a portable version…)

I’m not going to give blow by blow instructions to build the model yourself, but you should see enough examples of techniques used to address common elements in modelling rockets.

Now I have Rockets of the World, so I can use the dimensioned plans from that – small version follows, (deliberately too small to use, as its copyrighted).

But you can do a good job without. Using methods described in part 1, I was able to locate some perspective free views, at good resolution. Click for a larger image: Continue reading “Modelling CGI rockets, part 2, worked example”

As it came up in a couple of different circumstances, I thought I’d write a post featuring some of my Lunar renderings. The Moon was one of the first things I successfully rendered in 3d – The simple shape made the modelling easy, and just adding a colour channel texture and a bump map meant I could produce nice views of the Moon from any angle.

The current model.

The current version of my Lunar Model has 46 million polygons, and the craters and mountains are modelled using displacement mapping. In other words, the features are done with proper geometry, so the crater walls cast shadows.The colour texture map is about 1 gigapixel, so really large high resolution views are possible.
