Processing 3D data is becoming a more and more common part of many applications – many common workflows start with 3D digitization, digital editing, and, finally produce a tangible object through additive manufacturing. Throughout this whole process, visualizing 3D data is a key requirement. I will show that, especially when visual feedback should be provided to end users, but also within in-house processing pipelines, the Web browser is a highly attractive medium for this purpose. Customers and process engineers alike can both easily inspect 3D data sets on different kind of devices, including laptops, tables and smart phones, which creates a level of transparency throughout the process that was previously unseen. However, efficient in-browser visualization also comes with several challenges, which I will highlight during my talk, including portability, managing data complexity, and creating appealing visuals with manageable effort. As an example, I will focus on the automated processing and online visualization of sculpted objects, which are inspected and ordered online to then be 3D printed and shipped to the customer on-demand.
