Raycasting

Raycasting is a technique used in 3D computer graphics to determine the intersection of a ray with objects in a scene. It is commonly used in games, simulations, and other applications that require real-time rendering of 3D environments.

Raycasting in 3D Games

In 3D games, raycasting is used for various purposes, such as:

• Collision detection: Raycasting can be used to determine whether an object is in the path of a projectile or other moving object, and to calculate the point of impact.
• Object interaction: Raycasting can be used to allow players to interact with objects in the game world, such as picking up items or opening doors.
• Camera control: Raycasting can be used to control the movement and orientation of the game camera, allowing players to look around the environment.

Raycasting is a fundamental technique in 3D game development, and it is essential for creating realistic and immersive experiences.

Raycasting in Simulations

Raycasting is also used in simulations, such as:

• Physics simulations: Raycasting can be used to simulate the interaction of objects with their environment, such as the collision of a ball with a wall.
• Architectural simulations: Raycasting can be used to create virtual models of buildings and other structures, allowing architects and engineers to visualize and analyze their designs.
• Scientific simulations: Raycasting can be used to simulate the behavior of light and other electromagnetic waves, such as in medical imaging and weather forecasting.

Raycasting is a versatile technique that can be used to create realistic and accurate simulations of a wide range of physical phenomena.

Learning Raycasting

Raycasting is a relatively simple technique to learn, and there are many resources available online that can help you get started. There are also a number of online courses that can teach you the basics of raycasting, such as the following:
