摘要 |
<p>A system and method for drawing non-opaque objects with realistic refraction attributes. The system adjusts the pixel values of an object with a refraction index other than unity so that the resulting image approximates a refracted image. Adjacent pixel values are copied and blended with the pixel being rendered based upon a calculated refraction value. Refraction can be approximated as a surface effect by offset vectors, as a property of an object having parallel front and back surfaces and as an arbitrary object with non-parallel opposing surfaces. The more complex representations provide improved approximations of the refracted image. The resulting image presents a more realistic view of the refracted image. <IMAGE></p> |
