Progressive Ray-casting Volume Rendering with WebGL for Visual Assessment of Air Void Distribution in Quality Control

Fecha: 26.07.2019


Abstract

Due to a lack of ubiquitous tools for volume data visualization, 3D rendering of volumetric content is shared and distributed as 2D media (video and static images). This work shows how using open web technologies (HTML5, JavaScript, WebGL and SVG), high quality volume rendering is achievable in an interactive manner with any WebGL-enabled device. In the web platform, real-time volume rendering algorithms are constrained to small datasets. This work presents a WebGL progressive ray-casting volume rendering approach that allows the interactive visualization of larger datasets with a higher rendering quality. This approach is better suited for devices with low compute capacity such as tablets and mobile devices. As a validation case, the presented method is used in an industrial quality inspection use case to visually assess the air void distribution of a plastic injection mould component in the web browser.
