Method and system of rendering 3-dimensional graphics data to minimize rendering area, rendering time, and power consumption

A system to render three-dimensional graphics data, the system comprising:

• a rendering module to divide initially inputted first graphics data into a first static object and a first dynamic object, to perform a first rendering process with respect to the first static object, and to update a predetermined buffer with a result of the first rendering process, the first rendering result including rendered color information or depth information with respect to the first graphics data;
• a storage unit to perform a transformation process, to perform a portion of a second rendering process with respect to the dynamic object, to determine an updating area, and to store a portion of the first rendering result corresponding to the updating area;
• an output module to perform a remaining portion of the second rendering process with respect to the first dynamic object, to update the buffer with the result of the second rendering process, and to output a first image whose rendering is completed;
• and
• an updating area restoration module to restore the first rendering result of the updating area to the buffer by referring to the portion of the first rendering result stored in the storage unit to create a restored buffer, and to utilize the restored buffer as a second rendering result of subsequently inputted second graphics data.

A method to reduce the time, cost, and size of rendering three-dimensional graphics data, comprising:

• clearing a buffer;
• dividing first graphics data into a plurality of first static objects and first dynamic objects;
• rendering the plurality of first static objects to create a first rendering result;
• storing the first rendering result into the buffer;
• determining an updating area of the plurality of static objects;
• storing a portion of the first rendering result corresponding to the static objects into a storage unit;
• rendering the plurality of first dynamic objects to create a second rendering result;
• storing the second rendering result into the buffer to create a first image corresponding to the first graphics data;
• restoring the updating area stored in the storage unit to the buffer;
• comparing a reference point of second graphics data to a reference point of the first graphics data;
• and
• repeating the method using the contents of the buffer as the rendering result for a plurality of static objects in the second graphics data and without clearing the buffer, if the reference point of the second graphics data is the same as the reference point of the first graphics data.
