摘要： Procedure for rendering images in real time of three-dimensional models of items of jewellery Procedure for rendering images in real time of three-dimensional models of items of jewellery comprising at least one transparent or translucent stone having facets, which procedure comprises the steps consisting in determining a reference point in the stone, calculating the components of the normals to the facets of the stone in a discrete set of directions around the reference point and storing these components in a map of the normals, and simulating light reflections within the stone by calculating an approximation of the point of intersection between a ray and the stone using a simplified geometric shape of the stone and using, to calculate the direction of the reflected ray, a normal extracted from the map of the normals, corresponding to the point of the surface of the stone located in the direction of the point relative to the reference point.
