Projection mapping _process and test

Augmented polygon from koosi_lab on Vimeo.

I did test projection mapping on real object.
It is not perfect yet, the mapping is slightly distorted and animation editing isn't done yet
but I will make it better with completed animation.


A. Drawing guide Map

Set up the projector and 3d object position.
Then clon the computer and projector screen.
Open Photoshop in fullscreen and draw guide lines along the edges of the object.

This is the result of guide drawing.

B. Mapping in Maya

Import guide map file in Maya camera view,
then synchronize the guide map and 3d object by fitting camera setting.
This step is quite tricky. I need to see the details of each edges whether they're fit well or not.
Finally, lock the camera position and export the texutres from the camera view.

C. Reproject

Reproject the exported texture.
Now it is almost done.

These are the result of applying textures on real object by projection.
It is not very perfect but alomost closed.

Texture animation _draft

I applied different kinds of textures.
And before I set the object position and projection, I tried testing animaion.

This is just draft short time animaion to see how's the feeling.
I will adjust the detail texture, time length and transition.

Mapping texture test

I played around with texture animation.
Those are quite basic texturing but it is interesting the anmiation chaged by small adjusting.

I like this because it reminds Dazzle camouflage.

Complex model _final

Final polygon model

Modeling in Maya

I made more complicated model for final.
It was difficult to concern about angles if it works when it is projected.

Pepakura exporting and print in two A0, same as previous step.

Because it has many polygons, it should be printed in bigger paper. Otherwise, it will be very small but maximum size of printing paper is A0 so I decided them print in two A0.
Fortunately, it is spilted automatically two segments in Pepakura which makes easier.
There was some errors but they were not that big problem which I could simply handle it.

I imported them in Illustrator and resized for two A0 then printed in 300g Drafting paper.

Same as the previous step, I cutted the printed paper, folded and assembled.

Final model by paper folding

Making big size polygon object & test projection

I did 3d modeling in Maya and export in Pepakura.

And unfold the 3d model in Pepakura

I printed it as A0 size. Because default printing A0 paper is too thin, I used 200g thick kent paper (788x1091) which is slightly smaller than A0.
Then I cutted and folded paper.

This is the 3d object in real.

Next, I projected into this obejct and drew guide dots in Power point. Through the dots, I drew line map in Illustrator and reprojected the map into the object like below.
From this scene, I can guess how it look when I add animated texture.

And import map image in Maya camera view then modify the camera view to fit the map and model. It can not be perfect, so there is a chance to modify the model slightly. This step is needed to synchronize Maya camera and real projector.
