Deferred Shading for Multiple Real-Time Soft Shadows Rama Hoeztlein, Media Arts & Technology Program, UCSB |

ABSTRACT |
||
This technique allows any combination of traditional rendering and deferred shading. Shadows are implemented here using low-res shadow maps, 4x4 PCF with screen-space blur. The Shadow and Lighting stages may be combined for greater efficiency, or they may be separated for greater control. Traditional multi-pass rendering may even be combined with deferred shading used only for shadows. By separating deferred shading into stages, we can achieve a greater degree of control and flexibility while maintaining performance. | ||
