Saw a presentation on projection mapping using C4d, and just ran into this:

(hey, all you need is two bigass robots....) So, anybody doing stuff with LW?

could've tried, using stepper motors (yes, i read alot)

projection mapping, it's limited in it's potential, i'd rather make experiments with true holograms (kickstarter)

still cool though, haven't hear of people doing it using LightWave, but should be relatively easy.

or, cooler, mixing projection mapping and holograms.

In fairness, C4D's Projection Man toolset is easy-to-use and well-targeted for such workflows -- Projection Man is why C4D is popular for projection mapping and matte projection work.

I'm sure LW can do most of the same things, but the equivalent LW workflow and UX involved could definitely be made much more efficient and discoverable, esp. w.r.t. scaling calibration, parallax adjustments, and so forth.

THENNN there's people that might like to make some income this decade. :P

If you watch the "making of" it says that most of it was done in maya... and it seems that all the technical stuff was.

Edit... I see you were just posting it becasue you saw some stuff about c4d projection mapping. Thought you were saying it was done in c4d.

I did a few for tokyo dome concerts.
There's nothing special about it. You model the site as accurate as you can and project your animation using a front projection camera and then render that with another camera that has the same location of the projector in real life.
You can charge a lot for it because its a "physical fx".

Now, I like the sound of that.

FWIW: The presenter of the C4D lecture said, surprising everybody, that the render camera was in the location of the mythical "perfect audience member", which confused a lot of people, but he backed it up with some logic I can't remember and he'd done numerous installations. We grilled him on that point repeatedly and he stuck to his guns. I can't remember/reconstruct the reasoning. It may have been C4D specific.

Well that particular performance is only going to work for that camera view point, anyone else watching from the sidelines won't get the "perfect"view and the illusion of 3 dimentionality will be broken. It's all programmed, the camera, the screens the projector alignment, mimicking exactly the moves created in the virtual space.

I used to work for a company here in Budapest, they did lots of mapping under the disguise Freelusion, even for AGT. THey had a robot show too and dancers.
Personally I dont like this genre. Lots of color and contrast is lost during projection.

Well, that's not the fault of the animator. Howwever, one could stick with monochrome, and in this case use that super-high reflective material since the projection surfaces are so small.

I did a gig earlier in the year that was projected onto a physical model using Watchout. Pretty interesting software. I had a 3d model that was made off the same plans that a physical model was built. I did my render passes in LW, comped it in Fusion and reprojected the animation onto the 3D model in Fusion as an animated UV map. The UV render / 3d model was then (I think, I haven't seen the end result) reprojected on the physical model and aligned with the Watchout software running the UV image sequence.

With enough cameras you could do something like this and walk around the model and it will all sync up. It's pretty powerful stuff.

The work I did was nothing like the OPs video. There's a lot of motion control work going on there. Still, it can be really immersive if planned out well.

Once we tried to sell a monochrome idea to a client, it was a saudi show. They just hated the idea of being monochrome. They wanted to see a gigantic flashing-sparkling disgusting cesspool of stupid effects.

Cool. Reminds me of a James Bond Title Sequence.

Thanks, wibly, very interesting and nice to have links.

People tend to use these for BIG EVENTS, but it'd be interesting to make it something one sees everyday.

@jeric_synergy I agree, I think that software is usually used for big events. It's not cheap. The interface looks pretty 80s ghetto style. It is pretty powerful though. There's a bunch of tutorials on youtube about it. It was a pretty fun project where this was used on. It was for a local museum here doing a focus on the WW1 airwar. The model makers built a zeppelin and my friend built the balloon from the same plans. The idea was to have this 12-14 foot zeppelin hanging over the heads of the people in the exhibit. You'd hear it coming, the searchlights would find it and light it up, a night fighter made a few passes and eventually shot it down. I did a bunch of fire sims for it blowing up and they had lights inside to help it glow. I animated it starting to break in a V shape dropping out of frame (the physical zeppelin model). Like I said earlier, I comped it in Fusion and reprojected it on to the 3D model as an animated UV that matched the plans for the physical model. The net effect was like you're standing there watching this encounter happen over your head. I still haven't seen how it worked in the end but, the concept was really interesting.

The spaceship link is very interesting. Pour moi, the most interesting effect is when they make an opaque object appear to be transparent.

On the building stuff, it's when parts of the building appear to extrude or..... the opposite of extrude. Quite trippy.

It seems one of the bigger challenges is just getting a dark enough venue for it to be effect.

Hi.
We have done 3d mapping, using only lightwave :)
