Abstract
Provided is a method of accelerating ray tracing. The method includes extracting characteristics of an input ray at a ray scanner, determining a ray with characteristics similar to that of the input ray based on comparing characteristics of the input ray with characteristics of rays used in previous renderings, and conducting a set up for ray tracing of the input ray based on a ray tracing of the determined ray.
Claims33
A method of ray tracing comprising:
- extracting characteristics of an input ray at a ray scanner;
- determining a ray with characteristics similar to that of the input ray based on comparing characteristics of the input ray with characteristics of rays used in previous renderings;
- and
- conducting a set up for ray tracing of the input ray based on a ray tracing of the determined ray.
1 more element
A ray tracing apparatus comprising:
- a history database (DB) configured to stores characteristics and results of ray tracing of rays used in previous rendering;
- a ray scanner configured to extract characteristics of an input ray;
- and
- a data manager configured to determine a ray with characteristics similar to that of the input ray based on comparing characteristics of the input ray with characteristics of the rays used rays in previous rendering, and to conduct a set up for ray tracing of the input ray based on ray tracing of the determined ray.
1 more element
A method of ray tracing, the method comprising:
- extracting characteristics of sequentially input rays at a ray scanner;
- determining groups of the rays based on the characteristics;
- and
- updating a processing order of the input rays based on a group of the groups.
