🔍Ray tracing is a technique used in computer graphics to create realistic images.
💡Generating random numbers and random directions are essential in the ray tracing process.
🎯The intersection test is used to determine if a ray hits a sphere.
🖌️Adding materials such as specular reflections and diffuse reflections can enhance the visual quality of ray traced images.
🌐Ray tracing has many applications in areas like gaming, animation, and visualization.
What is ray tracing?
—Ray tracing is a rendering technique used to generate realistic images by simulating the path of light.
Why are random numbers important in ray tracing?
—Random numbers are used to generate random directions for the rays, which helps achieve a more natural look in the rendering.
What is the purpose of the intersection test?
—The intersection test is used to determine if a ray collides with a sphere, which is essential in determining the visibility of objects in a scene.
How can materials be added to ray traced images?
—Materials such as specular reflections and diffuse reflections can be added to surfaces to enhance the visual quality and realism of ray traced images.
What are the applications of ray tracing?
—Ray tracing is used in various fields, including gaming, animation, movie VFX, and architectural visualization.
