Computer Animation - Maid of the Loch Steam Engine

[thegeffc]

some great inforamtion here thanks

[clairebehun]

i enjoyed this vid

[kbj42016]

Wow, thanks! Now I understand. So Simple!

[maxmodeller]

@clydeferries Do you mean the steam engine will be replaced? If so, it's the first I've heard of it.

If however, you mean that the new high tech boilers will run on bio fuel, then that's got to be a good idea.

[clydeferries]

Is this taking into consideration that she will be converted to bio-diesel operation?

THANK YOU

[imzebaz]

damn

[imzebaz]

what sw did you use to make the animation? lightwave?

[maxmodeller]

@imzebaz 3D Studio Max with standard scanline renderer and video post for the glow effects. If I had the time I would re-render with Vray and better combustion type effects but unfortunately - time - I don't have.

[assariassari]

how did u do this ?... by which program u made it ? .. thnx

[maxmodeller]

@dave97202

Hi Dave,

Give me some more info regarding your project.

Unfortunately due to current work commitments, I am very busy at this time.

Is your project private or commercial?

Thanks to the author. Your video helped me a lot ;)

[youngfreedom93]

its fucking genious

[Zappyguy111]

...

**mouth open in awe**

[eclipse572]

This is really helpful, and the animation is just smooth, makes it great to understand.

[MYcareLEVELis1]

fully sik XD

[maxmodeller]

No, the steam is fed into the system to allow forward and reverse - whichever is required. Oh, and it's a paddle steamer - not a train.

Cheers

[naichengwei1]

what if the steam engine turns backwards, won't the train turn the wrong way? xD

[wisdomsp]

VERY NICE!

[Areldrich]

Very nice video!

[MrDavy86]

aff we gaw doon the watter

[rayunseitig]

The way the D valve is show is excellent. Great job.

[maloktrebado]

beautiful... perfect

[bucktheusa]

please post a steam locomotive

can't seem to find one as beautifully rendered as this.

I finally understand! One closes and the other opens. Ingenious!

[nbaietti]

beautifull work! congratulations! how did you do the gas animation? 3dsmax particles? post production on after effects/combustion?... loved it, man!!!

[maxmodeller]

Thanks.

Yes, particles and after effects to make it glow. Can't afford a decent effects plugin like afterburn or similar.

Cheers

[Strattonification]

I am trying to animate something similar to this an was wondering if you used 3ds max and if you could give me some help with the timing on the slide and piston as well as the steam effect you used?

[maxmodeller]

3D Studio was the modelling program used. The best way to time the piston/slide valve is to animate your piston first and make your slide move at half that speed (twice the amount of frames) as it feeds the cylinder for each stroke of the piston in both directions.

You will need to adjust your timings to take into account the time taken for the steam to pass through the feed pipes (in the real world this would be extremely fast and not good for this anim.

(See next reply)

[maxmodeller]

(Continued) I used a particle system that grew within the chamber and was linked to an animated dummy which dragged it along the pipes. Then a second paricle system grew within the cylinder to match the movement of the piston. Video Post was used with a glow filter on the particles to give the final effect. Remember, you only have to animate one cycle and repeat it in your post editing program to create as long a sequence as you want.

Hope this helps.

old & big

[JHx86]

that must be very efficient

[1Nibbie]

fantastic! Better then hollywood movies :)

[clivemain]

Another excellent video and very well illustrated too....very classy! 5*

[redbrackets]

so obvious now you have told me, i shall stand in the corner of the classroom ! but i have learned a lesson, Thanks

[redbrackets]

Hi, great animation! Is the crank balanced by the counterweights ? I would have thought that with two con rods they would have been 180 degrees but these are only 90.

[maxmodeller]

Hi,

Yes, when I began this study, I thought they should be 180 degrees but found out that the crank is at 90 degrees to aid starting (as well as other reasons). Apparently, if the engine stopped with the crank in line with the connecting rods, it would be extremely difficult to start. Having one big end at 90 degrees solves this by meaning the engine could stop and be started from any piston position.

[ck5056]

Very well illustrated, 5 stars. At first I thought the only way to push back the piston is by a spring at the other end of the cylinder.

Beautiful animation. You are an artist, sir.

[nemo1620]

Viewers should also watch the "Maid of the Loch Computer Animation" clip, which shows the double paddlewheel ship sailing around the loch.

[maxmodeller]

Thanks. What can I say - I enjoyed building the model and learning how these wonderful machines actually worked. If you ever get the chance to visit Loch Lomond, go and see the Maid of the Loch at Balloch. Her engines are undergoing complete renovation with new state of the art boilers. I will be there when she sails again - 27 years after being taken out of service.

[acharad]

Very good explanation of how a steam engine works.

Produces power stroke in and out, twice in a round

[pshisbey]

Very cool. Now I understand. Thanks.

[MindArts85]

a great animation !!!! i like it !!

[maxmodeller]

Thanks.

I enjoyed making it!!

[themanyone]

I was going to say "less efficient" but after some research I see that was just a popular misconception and misinterpretation of my day.

[boxpok]

Excellent animation work. What kind of boiler does the Maid of the Loch have? I would imagine it might have a scotch or cornish type. If so do you have video or detailed photos?

[maxmodeller]

I'm not sure what the original boiler was. It was stripped out as it was completely corroded.

The Maid will be fitted with a couple of brand new modern boilers apparently.

[maxmodeller]

Update: According to the Maid of the Loch Golden Jubilee Handbook, the Maid's boiler was a "Navy Boiler supplied by the Eagle Foundry of Rankin and Blackmore at Greenock"

It was oil fired.

[krhall78]

Nice Engine xD

24" High pressure cylinder and 48" Low pressure cylinder.

Can't remember the stroke, i think it was 51" if i remember right. xD
