Abstract
Provided is a ray tracing method including extracting, at a ray scanner, characteristics of a ray generated to render a current frame, determining a ray having characteristics similar to that of the generated ray based on comparing the characteristics of the generated ray with characteristics of rays used to render a previous frame, and performing ray tracing of the generated ray based on a result of ray tracing of the determined ray.
Claims21
A ray tracing method comprising:
- extracting, at a ray scanner, characteristics of a ray generated to render a current frame;
- determining a ray having characteristics similar to that of the generated ray based on comparing the characteristics of the generated ray with characteristics of rays used to render a previous frame;
- and
- performing ray tracing of the generated ray based on a result of ray tracing of the determined ray.

A ray tracing apparatus comprising:
- a ray scanner configured to extract characteristics of a ray generated for rendering a current frame;
- a data manager configured to determine a ray having characteristics similar to that of the generated ray based on comparing the characteristics of the generated ray with characteristics of rays used in rendering a previous frame;
- and
- a ray tracer configured to perform ray tracing of the generated ray based on a result of ray tracing of the determined ray.
