Realtime Interactive Computergenerated Integral Imaging Method Based on Ray Tracing
To improve the realtime interactive display performance and flexibility of the computer generated integrated imaging, the integral light field viewing model consistent with the structure of the optical reconstruction system in integrated imaging is constructed. A reversely traced ray for each pixel in the elemental image array is generated by integral light field viewing model, the elemental image array is efficiently shaded as all the rays are computed parallely through ray tracing technology. Experimental results show that, a point cloud model with 565 880 vertex, and a mesh model containing textures with 977 308 faces are optically reconstructed on the 4 K display system at a frame rate of over 40 fps, the system have interactive functions such as scaling, moving, rotation and fine adjustment. Getting rid of the virtual camera model, the method make realtime interaction more effective and convenient, and can be applied to the integral imaging based on lens array with different distribution patterns.
