What is a jamming signal?
Jamming, in electronics, broadcasting a strong signal that overrides or obscures a target signal. The techniques of jamming are many and varied, but most of them simply consist of broadcasting a powerful radio signal, modulated with noise, on the precise frequency of the signal being jammed.
Is signal jamming illegal?
The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. It is also unlawful to advertise, sell, distribute, import, or otherwise market jamming devices to consumers in the United States.
Which is the best algorithm for 3D collision detection?
Followup articles will cover implementations in specific 3D libraries. As with 2D collision detection, axis-aligned bounding boxes (AABB) are the quickest algorithm to determine whether the two game entities are overlapping or not.
How does collision detection work in physics engine?
The way a physics engine works is by creating a physical body, usually attached to a visual representation of it. This body has properties such as velocity, position, rotation, torque, etc., and also a physical shape. This shape is the one that is considered in the collision detection calculations.
How to create an optimal collision detection routine?
To create an optimal collision detection routine, we have to start planning and creating its basic framework at the same time that we’re developing a game’s graphics pipeline. Adding collision detection near the end of a project is very difficult.
Which is more difficult collision detection or Pong?
Collision detection in 3D is many magnitudes more difficult to implement than a simple 2D Pong game. The experience of playing some of the early flight simulators illustrated how bad collision detection can ruin a game. Flying through a mountain peak and surviving isn’t very realistic.
