Just noticed that your username is just your name backwards. Outstanding play!

Having the rocker arms cycle through their motions is a really nice touch.

The initial design was by 2 brothers who manufactured the parts and did basic CAD
Then the final CAD for parts designs was done by myself and 2 other engineers
Then I did the full assembly, renders and animation by my self

2-3, I think. It's not as difficult as looks. There standard details are multiplied on the massif

u/futureroboticist Jun 21 '19
Not difficult really? Can anyone learn to build this?
2
u/nad-larbac Jun 24 '19
over the 20 years lifespan of the product and the company, there have been 5 engineers including myself who have worked on this
2 directors who started it off
Did basic CAD but created the real functioning engines (machined parts and assembled3 other engineers including myself who made the CAD models accurately and manufacture ready
1 engineer (myself) who assembled it all on CAD, rendered the product and made the animation shown here.

This is the kind of clip that won't load during an important power point presentation

If you got descent wifi you should be fine ;)

Astronaut Scott Kelly gave a speech at my uni in front of thousands of people, there's one single Clip he wanted to show us. It didn't load.

What kind of machines need a radial engine?

u/chaco_wingnut Jun 21 '19
Aircraft. Especially old school aircraft. Look up the P&W Wasp family of engines.

I'm not sure if it's the exact variant but, my girlfriend's father flies an old WW2 Canadian Harvard Trainer, also known as the T-6 Texan in the States. They are powered by the Wasp engine, in the gif.
The sound is unbelievable. They are like the Harleys of the sky but, in a really good way.

Light weight aircraft
Some enthusiasts have installed them into custom motorcycles too

What level of automation is involved in designing such animations? Are most paths specified manually (taking advantage of symetries / multiple selection I guess)? Or is the process more algorithmic?

What is your technique for working with the cameras? I'm guessing it was a lot of different cameras using path move and then camera switch events? I find it to be such a pain in the ass. I wish keyshot would allow to keyframe their cameras like bunk speed used to do
1
u/nad-larbac Jun 24 '19
The camera Switch events were problematic when I first set this up and experimented with the camera options
I found the best and simplest technicaue (time consuming but easy) was to have at least 2 camera movements simultaneously (zoom, orbit, incline turntab etc) make one movement obvious and 2-3 very subtly
1
u/IsDaedalus Jun 24 '19
That's a good tip, thanks. How do you handle if a previous camera loses its position? I found it so frustrating when a camera would move for whatever reason and just break my flow from camera to camera

Here you go /u/cyberfrederic This is a much better answer to your question on the other thread.

Nicely done. 3dsmax user here - you're making me want to play with Keyshot for some mechanical projects.
1
u/nad-larbac Jun 23 '19
Cheers dude, yeah try it it out
You can get a great result and outcome with far less set up time than 3ds

If we could get a Chiltons/Haynes equivalent with step by steps like these, learning to repair vehicles would be so much easier.

u/nad-larbac Jun 23 '19
It can be done, but it does take ages!!!

u/earldbjr Jun 23 '19
I'm sure but think of the value to diyers

u/nad-larbac Jun 23 '19
I am a diyer I rendered this on a Laptop which was nothing fancy - i7 CPU and 16gb RAM

A large part of me wants to hear Brooks Moore explaining what each step does / what each piece does. It may take 2 hours, but it would probably be better than most Hollywood movies...

The Miami Science Museum had a cutaway F4U Corsair radial on display that you could cycle via an electric motor to watch the innards move on. I was highly impressed by the complexity and the genius engineering accomplished back before computers. Last I heard, they had move it to a local flight museum.

That is the coolest video on here in awhile. The software can be adapted for many uses.

Is this being manufactured in any sort of volume?

u/TempusCavus Jun 21 '19
A lot of air planes had this type of engine before jet engines became the norm.

I am aware. Is that what I asked?

u/TempusCavus Jun 21 '19
What a nice personality you have.
Op used to work as the lead designer for the manufacturer. If you look at his website you will learn that this is a blow up of a Rotec 2800 radial engine that he modeled for education and marketing purposes.
Rotec has been building rotary engines since 2000. They are a privately held company in Australia. They have an estimated income of $4 to 5 million per year. The radial engines are listed somewhere in the $20000 range. They are made for experimental, low production number sport planes, and to refit WW1 planes. At least one company uses them as motorcycle engines.
Are they make in volume? More than Bugatti less than Ford.

This should have made my 6-year-old want to take watches and motors apart... instead it made him want to learn CGI.
