Which of the following figures can be formed by intersecting a plane and a cube?
The intersection of a cube and a plane can be a triangle: but there’s no way to produce a circle, since none of a cube’s edges or faces is curved. The correct answer is (E).
What is CSMA CD techniques?
Carrier sense multiple access with collision detection (CSMA/CD), is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by transmitting only when the channel is sensed to be `idle`. When they do transmit, nodes transmit their packet data in its entirety.
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.
Which is better for collision detection AABB or bounding spheres?
Bounding spheres. Using bounding spheres to detect collisions is a bit more complex than AABB, but still fairly quick to test. The main advantage of spheres is that they are invariant to rotation, so if the wrapped entity rotates, the bounding sphere would still be the same.
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.
Which is an example of collision detection in Unity?
Unity collision code example. This article demonstrates the basics of Collision detection and how to create physical materials and triggers in Unity. First, you have to open the Unity project. Click on the GameObject in the menu bar. Select the 3D objects and pick the Terrain. Terrain will be added to your Scene View.
