Disclaimer: Iʼm not a videographerIʼll just share my experience of video-shooting.
Professionals are more professional.

Our video-shooting setup

Diffused video light x3 (two diffusers, one umbrella)Black, white, and other colored backgrounds
Sony α7III

I use totally the same setup for photo-shooting and video-shooting.
This is not the best for photos, but very convenient and mostly fine enough.

10

NOTE: For more serious photos, strobe is better

If you only need still photos, strobes are better than video lights.
But I like to use video lights to take photos and movies at the same time.

Photos for a figure
Short video clips are unexpectedly useful.

Crane overview①Give input②Put constraints for functionality and foldability③Conduct Simulation and form-finding④Calculate thickness and hinges for the desired tools

91

Step 1: input

The system converts a photo of origami to a 2D origami pattern for post-processing.
Users manually prototype, assign colors (mountain, valley, boundary), and take a photo.

92

Step 2: Simulation and form-finding

93

Step 2: Simulation and form-finding

The system simulates the folding transformation.
However, this “chair“ is bad as a chair.

94

Step 2: Simulation and form-finding
Backrest leans too much
Not symmetry

Seat not horizontal

Two edges do not touch each other
Edges floating from the ground95

Step 2: Simulation and form-finding

Users put constraint components to solve issues.

96

Step 2: Simulation and form-finding

Constraints are connected to a Solver.

97

Step 2: Simulation and form-finding

The system automatically finds a shape satisfying constraints.
Users can also manually modify 2D or 3D shapes, while preserving constraints.

98

Step 3: Fabrication

99

Step 3: Fabrication

The system assigns hinges considering the thickness, folding angle, and fabrication tool.

100

Step 3: Fabrication

Users can try different hinge structures for the same pattern.

Other Functions

102

Tessellation between two surfaces

Given two offset surfaces, the system generates a pattern between them.

103

Lampshade

The pattern was automatically generated from the offset surfaces.
The shape satisfies rotational symmetry.

104

Generalized Ron Resch pattern

Given an arbitrary polyhedral mesh, the system generates an approximated pattern.

105
