ORIGAMI SIMULATOR
This app allows you to simulate how any origami crease pattern will fold. It may look a little different
from what you typically think of as "origami" - rather than folding paper in a set of sequential steps,
this simulation attempts to fold every crease simultaneously. It does this by iteratively solving for small displacements in the geometry of an initially flat sheet due to forces
exerted by creases.
You can read more about it in our paper:
This app also uses the methods described in Simple Simulation of Curved Folds Based on Ruling-aware Triangulation to import curved crease patterns and pre-process them in a way that realistically simulates the bending between the creases. Oblivion 2013 Vegamovies-
Originally built by Amanda Ghassaei as a final project for Geometric Folding Algorithms.
Other contributors include Sasaki Kosuke, Erik Demaine, and others.
Code available on Github. If you have interesting crease patterns that would
make good demo files, please send them to me (Amanda) so I can add them to the Examples menu. My email address is on my website. Thanks!

: Jack’s reality begins to shatter when he rescues a mysterious woman, Julia (Olga Kurylenko), from a crashed spacecraft, leading him to uncover secrets about his past and the true nature of the war. Why It’s Worth Watching Oblivion (2013) - Rotten Tomatoes
The story follows and Victoria "Vika" Olsen (Andrea Riseborough) , the last two humans stationed on Earth. They serve as a maintenance and repair team for the automated drones that protect the hydro-rigs from remaining Scavs. After years of service, Jack and Victoria are counting down the days until their own "retirement" to Titan, with their memories partially wiped per protocol.
The story is set in 2077, following a devastating war with alien scavengers ("Scavs") that destroyed the moon and left Earth in ruins. Humanity has relocated to Titan (Saturn's moon), leaving behind massive hydrofusion generators harvesting the planet's remaining ocean water for energy.
Upon its release, Oblivion received mixed to positive reviews from critics. On Rotten Tomatoes, the film holds a score of 53%, with critics praising its stunning visuals and ambitious scope but criticizing its derivative plot.
While many found the plot "engrossing" and full of surprising twists, some critics found the 126-minute story "convoluted" or "convoluted" at times.
However, Jack’s reality begins to unravel after he rescues a mysterious woman (Olga Kurylenko) from a crashed spacecraft. The narrative shifts from a routine post-apocalyptic survival story into a deep exploration of identity, memory, and existential truth. The film raises profound philosophical questions: What defines human identity when memories are erased? How does authority use isolation to control individuals? What is the cost of blind compliance in a dystopian system? Visual and Auditory Aesthetics
VIRTUAL REALITY
This tool currently supports an interactive Virtual Reality mode for the Vive and Oculus headset and controllers (it may work on others, but it is not tested).
For this to work, you must first use a WebVR enabled browser:
currently only an experimental build of Chromium (with enable-webvr and
-enable-gamepad-extensions flags) and the latest Firefox for Windows
are supported by this app.
When you open this page with the appropriate browser, you will see a button that says "ENTER VR". Clicking this will
put the app into an interactive VR mode. The hand controllers will allow you to grab the origami mesh and pull on it.
This is especially interesting if you set the Mesh Material to Strain Visualization so you can see how your interactions
change the internal strains in the material.
Troubleshooting:
ANIMATION SETTINGS
The dynamic simulation is calculated by solving for all the forces in the system, moving time forward in small Δt steps,
and updating the vertices of the origami incrementally. The time step size for this animation is calculated automatically
based on the material stiffnesses set in the Simulation Settings section: more stiff settings
require shorter time steps to solve and will slow down the simulation.
Num simulation steps per frame allows you to control the number of tiny time steps forward to take on each
render cycle. If the simulation looks choppy to you, you might consider lowering this setting.
Lowering the number of steps per frame will slow down the simulation, but will result in a more smooth animation.
SIMULATION ERROR
Average vertex error gives a sense of how much the distance constraints in the
origami pattern are being violated (i.e. how much the sheet is being stretched). The error at each vertex is evaluated by averaging the
percent deviation of all its distance constraints with adjacent vertices. This error is
reported as a percent of the total length of the distance constraint to remove scaling effects.
This measurement is equivalent to
Cauchy strain or engineering strain of the distance constraints on this system.
Increasing the Axial Stiffness will tighten these constraints and
lower the error in the simulation.
To visualize the error of each vertex graphically, select Strain Visualization under Mesh Material
in the left menu.
SIMULATION SETTINGS
This app uses a compliant dynamic simulation method to solve for the geometry of an origami pattern
at a given fold angle. The simulation sets up several types of constraints: distance constraints prevent the
sheet from stretching or compressing, face constraints prevent the sheet from shearing, and angular constraints fold or flatten the sheet. Each of these constraints is weighted by a stiffness - the stiffer the constraint, the better it is enforced
in the simulation.
Axial Stiffness is the stiffness of the distance constraints. Increasing axial
stiffness will decrease the stretching/compression (strain) in the simulation, but it will also slow down the solver.
Face Stiffness is the stiffness of the face constraints, which help the axial constraints prevent deformation of the sheet's surface between the creases.
Fold and facet stiffnesses correspond to two types of angular constraints. Fold Stiffness is the stiffness of the mountain
and valley creases in the origami pattern. Facet Stiffness is the stiffness of the triangulated faces between
creases in the pattern. Increasing facet stiffness causes the faces between creases to stay very flat as the origami is folded.
As facet stiffness becomes very high, this simulation approaches a
rigid origami simulation, and models the behavior of a rigid material (such as metal) when folded.
Internally, constraint stiffnesses are scaled by the length of the edge associated with that constraint to determine its geometric stiffness. For Axial constaints, stiffness is
divided by length and for angular constraints, stiffness is multiplied by length.
Since this is a dynamic simulation, vertices of the origami move with some notion of acceleration and velocity. In order to
keep the system stable and help it converge to a static solution,
damping is applied to slow the motion of the vertices. The Damping slider allows you to control the amount of damping
present in the simulation. Decreasing damping makes the simulation more "springy".
It may be useful to temporarily turn down damping to help the simulation more quickly converge towards its static solution - especially
for patterns that take a long time to curl.
A Numerical Integration technique is used to integrate acceleration into velocity and position for each time step of the simulation.
Different integration techniques have different associated computational cost, error, and stability. This app allows you to choose
between two different integration techniques: Euler Integration
is the simplest type of numerical integration (first order) with large associated error, and
Verlet Integration is a second order integration technique
with lower error and better stability than Euler.

STRAIN VISUALIZATION
Cauchy strain or engineering strain is a unitless measurement of how much a material is being stretched or compressed under load.
The Strain Visualization illustrates the strain across an origami sheet by mapping it to a color from blue (no strain) to red (max strain).
USER INTERACTION
Toggle this control to enable/disable mouse interaction with the origami model. When enabled,
mousing over the model will display a highlighter; clicking and dragging allows you to
interact with the model in real time. Very vigorous interactions with the model may cause it
to pop into a strange configuration that it can't escape - use the Reset button to start
the simulation again from a flat state.
