| Abstract: | The realistic representation of light-bleed effect is one of the key topics in real-time computer graphics. Realistic simulating this nature phenomenon has two main aims, which are reality and real-time rendering. To this aim, an algorithm to simulate light-bleed effect realistic and real-time is introduced. Implementation oflight-bleed effect is realized by using Microsoft visual studio, DirectX9.0 and shader technique. The implementation result indicates that this algorithm is feasible and effective. |
