Steam engine

Postby Navarre » Saturday 6. November 2004, 15:29

Hi everybody,

quite a while ago (something about 10-15 years, I guess) I tried to animate a steam engine, or rather the system of connected rods driving the wheels (see picture below). The idea was using skeletons to animate the hole thing just by turning one handle (e.g. one of the wheels). But back then the rendering software (I think it wasn't even Real in the beginning...) lacked the possibility to constraint the movement of the bones in a suitable way. All I managed to do was a keyframe animation, animating all parts manually.

After playing a while with RSv4 the original idea came back to my mind and I gave it another try. Using a combination of skeletons and some constraints (just a few lines of RPL code) I managed to achieve my goal (finally - never ever give up :) ): There's just one master skeleton which controls the position and rotation of all the other objects.

Here are the final animation

(~1 MB - didn't get it smaller :?:)

and the project file
http://home.arcor.de/navarre/rs3d/Locomotion_Anim_04.zip.

Regards,
Eckart

Hi Eckart,

That's a very nice animation. Are you planning to make the rest of the machinery too?

Arjo.

Wonderful work Eckart !
I am a railfan as well and have been threatening to model a locomotive for years; I think you have provided the necessary inspiration (got a setup for a Lima3-truck Shay lying around ? ;).
Could I trouble you to post or mail me the blueprint image; I am curious.
I think I can figure this out, but, a tutorial or a brief overview of the setup process would be great.
Thank you for posting this,
Zaug
