TITLE: RTDR-1 COUNTRY: United States of America WEBPAGE: www.bigonmars.com RENDERER USED: POVRay 3.5 (MegaPOV 1.1) TOOLS USED: Moray, PoseRay, Poser 5, World Machine, Leveller, VirtualDub, TMPGEnc, pjBmp2Avi, Audacity, Moray Domes plugin, M.O.P.S. CREATION TIME: months ! which shows pretty low productivity HARDWARE USED: Athlon Thunderbird, 2.0875 Ghz. VIEWING RECOMMENDATIONS: It does have sound, but the sound is background. ANIMATION DESCRIPTION: ”When traveling on Mars, you need to carry your own air, water, and food. Vehicles tend to be big. Two Drillers are returning after drilling for water in Tithonium Chasma, in Valles Marineris.” They are driving a Rough Terrain Drilling Rig (RTDR). Note the animation has sound, although it stands alone without it. DESCRIPTION OF HOW THIS ANIMATION WAS CREATED: This is my first IRTC submission, and I found I had a hard time getting everything together. This animation shows a tank tread system I have been (slowly) working on. It is very roughly based on the M.O.P.S. Atelier system (http://perso.wanadoo.fr/mops/atelier2.htm), although that is in French and I am not ;-) so I hope I have attributed it properly. I have made some significant changes to it by using a trace macro to find the low point for each of the road (bogey) wheels. My system has idlers, sprockets, returns, and road wheels; all 3 of them are here although only the road wheels have special processing currently. I had some problems with the macro’s at the last minute, and based the average position of the tank on road wheels 2 and 5, and you can see the problems this causes in a few frames. I had it averaging all the wheels and taking max wheel travel into account, but had some vector issues so I had to drop it for the competition (and almost missed). The red suspension cylinders are actually some trace() macro debugging statements, but I left them in as they don’t look too bad. I plan on changing my macro’s to allow several different types of suspension, but that’s for later. However, with very few roads on mars, most types of tank suspension wouldn’t have the high amount of wheel travel necessary, so the cylinders aren’t too bad, they just need more detail. The landscape is a series of height fields at ever decreasing resolution that blanket the area of 8S 284E on Mars, in the center of Valles Marineris. I took Mars MOLA data, exported it, and then enlarged it and eroded it with World Machine. For the space port and city bases, I had to use Leveller to more precisely control the exact heights at areas to match the Moray objects. Getting scales to work properly with this was tough; in particular, the ground under the tracks is a tad rougher than shows well due to vertical scaling issues. The ‘city’ that you can see briefly at the right hand side of the screen you will hopefully see in much higher detail, but I had to cut most of it out for the initial zoom in. This animation was intended to be a brief intro while the camera zoomed into the city, but I “missed” with the first animation, so you can see the camera stop, then back up to zoom into the RTDR (Rough Terrain Drilling Rig). I shot a middle scene so I could preserve the initial zoom in. I used both Viking images for the color of the ground as well as some custom textures. The bump maps didn’t turn out to be as large as I hopped, but the first scene had already shot and missed by the time I saw it, so I hope to improve the ‘roughness’ of the ground in future images. The individual frames were shot at 512x384 with the intention of motion blurring with Virtual Dub (virtualdub.org) but with the major city shot showing the narrator leaving the city pulled at the last minute, I just left it at 512x384. If you have audio turned on, the voices come from AT&T “True Voice” technology, from a speech demo page. Any pronunciation errors are thus not mine ;-) I changed spelling of a few of the words to coerce it into being hopefully correct. The Poser models are Mike 3 and Victoria 3 with a few morphs, although I forgot the ‘vocal tract’ morphs so I didn’t try and sync the sound track with them. The space suits are from poserstyle.com. The city uses the “Domes” plugin for Moray. I did all of the modeling on the terrain, RTDR, the space port, and the city, including the wheels, as well as the trace() program to make the tracks follow the terrain (with the belts ‘winding’ around the wheels from the M.O.P.S. macro at the above mentioned site).
