In summary, the conversation is about coding the behavior of a 2d water ripple for a game. The person is seeking help to determine the height and speed of the waves, as well as the decaying rate of their length and height. They are advised to study 'gravity waves' to find the necessary rules for their project.

Hi,

I am trying to code the behaviour of a 2d water ripple, like when something falls into or onto the water, it is for a game so it doesn't have to be exact but I want it to be procedural instead of a fixed wave. So I like to know several things:

What determines the height of the waves? (probably volume + weight of object dropped?)

What determines the speed of the waves?

What is the decaying rate of the waves length and height. By how much is the second wave smaller then the first etc?

Any kind of help is greatly apriciated!

Study up on 'gravity waves'. That should give you all the rules you require.

Ah, the right search term brought up some usefull results, thanks a lot.
 

Related to Understanding Water Ripple Behavior

1. What causes water ripples?

Water ripples are caused by disturbances in the surface of the water, such as wind, rain, or objects being dropped into the water. These disturbances create a force that causes the water to move in a circular motion, creating ripples.

2. How do water ripples travel?

Water ripples travel in a circular motion from the point of disturbance. As the force of the disturbance moves outward, it creates a wave-like pattern that travels across the surface of the water.

3. Why do water ripples appear to spread out?

Water ripples appear to spread out because as they travel, the wavefront widens due to the circular motion of the water. This spreading out is known as diffraction and is a characteristic of all wave behavior.

4. What affects the speed of water ripples?

The speed of water ripples is affected by factors such as the depth of the water, the density of the water, and the strength of the disturbance that created the ripples. Generally, the deeper the water, the faster the ripples will travel.

5. How do water ripples interact with each other?

When two or more sets of water ripples intersect, they either combine and reinforce each other (constructive interference) or cancel each other out (destructive interference). This interaction is dependent on the amplitude and frequency of the ripples.
