3D PROJECTION MAPPING

[fordaloveable]

And also.. in case of 1 projector its do-able but with a multiple projector setup it becomes very confusing since you have overlapping beamers in that case the "live drawing" bit won't help much cause you would have to place the projectors at exactly the same positions -in real world- as when you did during the drawing test. Its not managable in bigger projects.. in my humble oppinion ;-)

Indeed great work! About the reverse enginering by taking a snapshot of the drawn grid.. it still remains a challenge to line up the 3d model to that snapshot(lensdistortion beamer vs VOF of the 3d camera etc) Well done though. My guess is that if you change the video camera angle, the perspective will seem to be off. The brain is quite tollerant but the spectator viewpoint is the tricky part. great job!

[simplydesigner]

Yes,correct!Passing through lots of steps can lead to errors in final output,but once you get the hang of it you'll remember all the right output dimensions,and if it happens just some scaling would solve the problem:-).

Concerning viewpoints,the specator's 100% illusion position is exactly the aperture width of the projector pointing backwards(for complicated non planar walls,viewers have more restrictions in space,while for planar 3d mapping on a facade,position is not a big concern).Bye!

@simplydesigner

thx for your response! Although i understand the process and what you mention about the aperture width.. i still have issues regarding the translation/matching between the projectors lens properties to the 3d cam. In 3dsmax the aperture width is set in the rendersettings but the FOV values are in the camera itself. If you check the test on my channel, this one i did on calculations(no warping) distance from the beamer to the maquette & adjusted vof in 3d while projecting.

[simplydesigner]

personal TIP: just fire up any drawing software,draw on multiple walls,take a snapshot.

now you have a perfect scene picture - background layout picture in order to reverse engineer the room using after effects + 3d anim.otherwise use program bricks software for real time quad vertex warping,although not much realism.

Realism is the whole point of "3d mapping".The good illusion positions itself as "Video Art" rather than club VJing.i know this will help.

cheers

Any chance of a full tutorial,as there isn't a decent one anywhere to be found?

that's enough go back to the closet

portal 2?

[lexuscafe]

May i have a copy of this video to project this at home ?. Please : - )

[simplydesigner]

:-) it's not so hard to do,being a common room corner:-)

although the camera(proj position) has both very specific aperture width and position in space.cheers!

Song please!!!

what music is that

[nannolino]

really nice! congrats! I was wondering about the lines grid animation during the early seconds... did you programmed the lines? Or its everything keyframed in After Effects?

[simplydesigner]

@nannolino the neon grid was assembled and keyframed in 3danimsft simulating real lighting.not much after eff!

just like a reverse engineering:)

[nannolino]

@simplydesigner ok thanks for explaining! (-:

Hello. How did you create the animations in the last section? With the extrudes and the shades? 3d studio max?

[simplydesigner]

@TheKudejudas yes,more like c4d :-).the anim is actually very simple,but you need to be more than a vj in order to make it fit on the wall.

[simplydesigner]

Thanks :-)

It was done with a new 4000 lumen projector!

[DanielamUga]

Which projector did you used? BTW Very good clip
