Projection mapping testing_3: Tracing the edges of the construction III
I did all the same steps for this testing. Foe this time, the difference was that I put the smaller-scale box on the desk horizontally, without angles, which meant the front side of the box was facing toward the camera horizontally. When I did the mapping stuff, as the box was horizontally settled on the desk, it was much easier to find out the right place to project directly.
Front side: paper cut based on a subway illustration, showed on vellum paper.
* Why choose vellum paper? This question leads to the materials issue.
[The choice of the materials:
Texture of the frame (borders): option a, cardboard; option b, foam care; option c, plywood (for future)
Color of the frame (borders): white. To consider about the mapping is with bright colors, the soleplate should be clean. In this testing, the frame is the soleplate for the mapping. I believe the white frame can be helpful to the final mapping view, as no color will be mixed with the colors of the mapping.
The screen: made of vellum paper. Vellum paper is light, transparent, white, and perfect matches to the mapping, and the video.]
a, Projecting horizontally;
b, Projecting with a random angle. (Just turned the box with a random angle, no movement of the tripod/ projector.)
The box is set with tree-shaped paper cut in front. The trees can make another layer for the mapping.
The views of adding another layer with these trees.
The shadow of the tree projected on the front side with the subway illustration made the mapping to be a kind of three-dimensional stuff.
