A very basic wind simulation!

We have recently implemented a very basic wind-system for our project. 

Unity has its own built in Wind Zone components that can be added to terrains.
However, there is no built in wind-components that affect rigid bodies or simple game-objects.
Hence we decided to implement our own implementation of wind in unity.

Wind Implementation on Rigidbodies in Unity:

3D forces with fixed magnitude and direction are applied on the planks (rigid bodies) of the bridge.
This is done with Unity's built in addForce-function and will make the bridge sway in a wind like motion.

Project specification

Team: Make HOOKE great again Team members: Adam Torkkeli-Johansson (adamjoha@kth.se), Ramtin Erfani (ramtin1995@gmail.com), Gabriel Gessle (gessle@kth.se) Project: Rope Bridge Simulation The simulation that we would like to do is a simulation of a classic rope bridge. To do this we plan on using spring forces between certain points on the rope bride to simulate a “hanging/bouncing” behavior. This project is inspired by a previous project in the Models and Simulation course called “Epic Rope Bridge”. We plan on using Unity to make this a real time simulation and like stated above we intend to use spring forces between points on the bridge to simulate the bridges behavior. Although there is built in support for spring systems in Unity we plan on implementing our own versions of spring behaviour using Hooke’s law. As a start we plan on implementing either Euler or Runge-Kutta (RK4) integration methods for location approximations. If we have enough time we will also i...

Piecing Everything Together - Our Final Project

Below is a summary of all our implementations (and their respective purposes) in our project.  A spring implementation (Hooke's Law)   - In order to simulate the elasticity of the rope-bridge. A shatter implementation   - In order to simulate the planks breaking. A pressure implementation   - In order to simulate when the planks should shatter. A wind implementation   - With the purpose to simulate and demonstrate the elasticity of the rope-bridge. These implementations was finally pieced together and the result is shown in the video below: https://i.gyazo.com/04c8f609283e1aaaf41d685b571e2475.mp4

Pressure calculation on planks

Bild
We've recently implemented a feature that allows us to calculate the pressure on a given plank. This allows us to set a threshold whenever we want the plank to shatter (using the shatter implementation we recently made a post about). This is what it currently looks like if we manually increase the mass of our cube: To accomplish this simulation, we used the physics formula for pressure which is: P = -F/A Where P is the pressure, F is the magnitude of the normal force and A is the area of the collision. To get P, we first of calculate the normal force using the following formula: F = m*g*cos(theta) Where m is the mass of the object, g is the gravitational field strength and theta is the angle of the inclined surface (currently only looking at the incline on the x-axis, we will be looking into expanding this to atleast one more axis). The mass of the object and constant g are easy to grab, theta however is generated by looking at the difference in rotation of the object ...
