Abstract

The present invention provides a 3D light field rendering method and device. The method includes: spatially transforming a 3D model to generate a 3D scene; setting a plurality of cameras on the 3D scene for photographing and collecting to obtain a plurality of camera-centered 3D scenes ; Cut and transform multiple camera-centered 3D scenes to obtain multiple homogeneously cropped 3D scenes; perform perspective division on the Y-axis corresponding to multiple homogeneously cropped 3D scenes to obtain multiple normalized device spaces; Perform rasterization on multiple normalized device spaces to obtain multiple window spaces; perform fragment shading on multiple window spaces to obtain a frame buffer object containing image information from multiple perspectives; use the frame buffer object to draw a blank rectangle on the screen Perform coloring to obtain naked-eye 3D light field information; display the naked-eye 3D light field information on the corresponding nano-grating screen. This solution can accelerate the popularization of multi-view, nano-grating-based naked-eye 3D display technology.

Description

technical field [0001] The present invention relates to the technical field of 3D light field rendering, in particular to a 3D light field rendering method and device. Background technique [0002] Glasses-free 3D is a display technology that realizes left and right eye parallax without using head-mounted equipment, red-blue / polarized glasses, and switchable glasses to produce stereoscopic vision. [0003] The naked-eye 3D rendering methods proposed in the prior art all have different problems. One of the naked-eye 3D rendering methods is realized by a display based on a cylindrical lens proposed by a certain company. The display uses an ASIC (Application Specific Integrated Circuit) to complete pixel redistribution process, it can support dual-view / nine-view glasses-free 3D display. The pixel reallocation process is a process of synthesizing independently and parallelly rendered multi-view images into a single image compatible with glasses-free 3D devices. This method has...
