    Bounce
In summary, the conversation discusses the equations needed for bounce in a 3D physics simulation. The bounce velocity is determined by the coefficient of restitution, initial height, and velocity. The angle at which the sphere hits the polygon will affect the bounce, but it will still bounce off at the same angle from the normal. The properties of light and edge contact also play a role in the bounce.

Finding the "bounce equation"

Due to reasons forementioned, I am unable to access the necessary data required to avoid the release of the following information:

I am making a 3d physics simulation. What are the equations for bounce based on the velocity and elasticity of a sphere when it collides with a polygon based on the point of impact? I know the response should be different if the sphere collides with the edge of a polygon instead of the face because the input vector would become somewhat extraneous, as the point of impact would have lost its collinearity.

The "bounce velocity" only depends on the coefficient of restitution the initial height and the velocity.

Wouldn't the only thing be different is the angle at which the sphere hits the polygon? In which case it will bounce off at the same angle from the normal

Would it exhibit the same reflective properties of light? And what about edge contact?
 

FAQ: Calculating Bounce Equations for 3D Physics Simulations

What is the "bounce equation"?

The "bounce equation" is a mathematical formula that describes the motion of a bouncing object, taking into account factors such as the initial velocity, gravity, and elasticity of the object.

Why is the bounce equation important?

The bounce equation is important because it helps us understand and predict the motion of bouncing objects, which has practical applications in fields such as sports, engineering, and physics.

How is the bounce equation derived?

The bounce equation is derived using the principles of classical mechanics, specifically the laws of motion and energy conservation. It can also be derived using the concept of elasticity, which describes how much an object can deform and return to its original shape.

What variables are included in the bounce equation?

The bounce equation typically includes variables such as initial velocity, acceleration due to gravity, the coefficient of elasticity, and the height of the bounce. Other variables, such as air resistance, may also be included depending on the specific scenario being modeled.

Are there different versions of the bounce equation?

Yes, there are different versions of the bounce equation that may vary in complexity and the variables included. Some versions may also be specific to certain types of bouncing objects, such as a ball or a spring. It is important to use the correct version of the equation for the specific scenario being studied.
