Title:
TRANSPARENT POLYHEDRON RENDERING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/005757
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to the technical field of image rendering, and provide a transparent polyhedron rendering method and apparatus. The method comprises: obtaining a reflected light color of each position of a back surface; sampling and obtaining a refracted light color in a background image or an environment map according to a refracted light direction of each position of the back surface; obtaining a color of each position of the back surface of a transparent polyhedron according to the reflected light color and the refracted light color of each position of the back surface; obtaining a color of each position of a front surface of the transparent polyhedron; performing weighted mixing on the color of each position of the back surface and the front surface of the transparent polyhedron according to a first weight coefficient to obtain a rendering color of each position of the transparent polyhedron; and rendering the transparent polyhedron according to the rendering color of each position of the front surface of the transparent polyhedron.
