terraforming

Solar Observatory

I decided to learn about compositing; I have been trying to create a number of images with mesh terrains, and they have basically killed my computer when trying to render. Compositing seemed offer me an optional way of crating some of the images in my head with fewer polys!

This is a follow-up to this image, and takes place on a mostly terraformed Venus. This is an early outpost, a scientific community established to study the sun, particularly the solar wind (Venus has  little or no geo-magnetic field)

The main issue I ran into was building colour; the logical choice - white or off white - simply made it look like Mos Eisley!

The dome building was a simple half sphere; with my first thoughts for the image I did start modelling the interior and there are still remnants of that - a floor and lift shafts. The tower isn't mine at all - it's by Serg Sobolev and is part of the DCCGI Buildings collection, available over at http://www.foundation3d.com

The solar wind detectors (the top) also started life as simple sphere objects.

The radio telescope is a NASA model, hacked a little bit, and sat on a version of the base used for the solar wind detectors.

The vehicles were actually built for another image - a Mars colony idea. They are essentially a single decker bus-sized vehicle on balloon tyres. They didn't turn out very interesting, but are fine for distance shots like this.

The background image is the Yelan desert in Iran - I came across it on the interwebs and it was pretty much exactly what I was looking for. You'll get an idea of its real scale when I tell you that the tracks my vehicles are following are actually the single set of tyre marks left by a 4x4!

To get some irregularities in the shadows of buildings and vehicles, I added a deformer object to each of the plane objects. This also enabled me to create an irregular terrain around the base of the buildings.

I kept the texturing pretty minimal; the concrete texture on the buildings is from Total Textures "Aged & Stressed", the Solar Wind Detector top is from Total Textures SciFi. The texture on the base of the SWD is by Philip K. The windows and the telescope whitish paint texture are mine.

The scene was lit with a single sun and HDR sky.

Practicing: Terraforming Venus

This is just a sketch, an excuse really, to create a planet in Photoshop… It came to me recently that I hadn’t created any planets in Photoshop for over 8 months - all had been made in C4D.

I also recently read an article on terraforming, part of which had a bizarre argument that we should terraform Mars and/or Venus because we’re breaking Earth - as if it’s easier to terraform another planet than stop destroying the one we’re on already! Anyway, that got me thinking about Venus and Carl Sagan’s old idea about using modified blue algae to alter the existing carbon dioxide-rich atmosphere. I know he later rubbished it himself, but it still sounds cool.


Terraforming Venus
Anyway, so here we are: 100 years into the future and a terraforming station in orbit around a changed Venus… the carbon dioxide atmosphere has been greatly reduced and the oxygen levels increased. Thin clouds already exist and the clear skies reveal continent-wide solidified lava flows and enormous caldera of extinct volcanos.

The texture for Venus was created using an image of pealing paint or plaster as a bump layer and over the top layering an image I made from ESA satellite photos of the Moroccan desert.

The space station includes bits downloaded from the forum discussion on Greebles at Foundation 3d as well as the spheres at the bottom from kennyscrap.com

I know the windows are in the wrong place for a station creating artificial gravity from centrifugal force, but they looked pants in the right place.

The space station was finished and textured in Cinema 4D and the final image was composited and rendered in Cinema 4D. The finished render was sent back to Photoshop for additional color correction and FX.
