What is the difference between ray tracing and ray casting?
An example of an AI chatbot conversation about ray tracing vs ray casting in graphics APIs.
What is the difference between ray tracing and ray casting?
Ray tracing simulates the way light interacts with objects to create realistic images, while ray casting is a simpler technique that determines visibility by projecting rays from the viewer's perspective.
Which one is more computationally intensive?
Ray tracing is generally more computationally intensive than ray casting because it calculates reflections, refractions, and shadows, leading to more realistic images.
Can you give examples of where each is used?
Ray tracing is often used in high-end rendering for movies and video games, while ray casting is commonly used in 2D games and applications where performance is critical.
Are there any modern graphics APIs that support both?
Yes, modern graphics APIs like DirectX and Vulkan support both ray tracing and ray casting, allowing developers to choose the best method for their needs.
