Abstract

In terms of light field image array generation, the traditional method of multi-view parallax image synthesis has problems such as computational redundancy and slow pixel mapping. We propose a new design method for light field image arrays for 3D printed images based on backward ray tracing techniques. The farthest point of collision is found when a ray collides with an object. The rendering time is greatly reduced compared to traditional methods, and only related to the resolution of light field image array. Combine with microlens array, 3D printing image with continuous and dynamic parallax effects is obtained, the correctness of the algorithm is proved.
