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.

After chatting to Matt, co-author of “N1 for the Moon and Mars“, I decided to dig out the meshes I did for that, and come up with some new renders. It was a mad dash to get it all out in time for publication, and I didn’t have time to explore all the options.
Quick introduction. I have recently been working on Chelomei’s UR-700, his Universal Rocket System, based on a design unit that eventually became the Proton. It was intended to replace the N-1 as the vehicle to take the Soviet Union to the moon.
Thanks to a comment left on these forums, I was refered to a website which had photos of something I never knew was built – a large scale model of the UR700, for vibration testing! It was made at 1/10th scale.
Before we get started, here’s a render I did, which shows you the overall configuration. I think this will help you understand the layout.
There is still much debate about why the Soviet Union – which was consistently way ahead in the early days of space exploration, failed to beat the USA to putting a man on the Moon. But while there is some disagreement over which factors were the most important, there is considerable consensus about which factors drove this.
They started later.
The USA made putting a man on the Moon the key national objective, from before they had even put a man in orbit. Pretty much the entire space program focused on this objective. By the time this became a national objective in the Soviet Union, 2 years later, time was very tight to develop a powerful enough rocket, and get the required expertise in flight systems.
Also, at the time the speech was made, the Soviet Union was so obviously far ahead, they did not take the US intention seriously.
Identifying N-1 variants. I mentioned this briefly in an earlier post, which featured some images I stitched together from video, but here it is in a bit more depth.
You are generally trying to distinguish between 5 different N-1 variants in photographs, the four that flew, and the weight model. This is most easily done via the colours, though there are several other differences.
This post is not about ALL the differences between the variants, just about how to tell which rocket is which.
N1-3L, the first flight.
This is easy to identify, as it is the only one with entirely grey first and second stages. The third stage is half white, with the white part facing upwards on the transporter, which is the side away from the gantry once the rocket has been erected. It was transported to the pad in winter, and there are photos of it with snow on.
Note that there was no green on any of the N-1 variants! This is a widely held misconception, as many museums show it as green, (including the London science museum, and many Russian museums too). Olive green was only used to camouflage missiles, (and green would make lousy camouflage in Baikonur at the best of times). This error has spread to the point where photographs have been tinted to make them look green). And sometimes it was just poor quality film stock.
