Abstract
We introduce a novel method for rectangular selection of components in large 3D models on the web. Our technique provides an easy to use solution that is developed for renderers with partial fragment shader support such as embedded systems running WebGL. This method was implemented using the Unity 3D game engine within the 3D Repo open source framework running on a web browser. A case study with industrial 3D models of varying complexity and object count shows that such a solution performs within reasonable rendering expectations even on underpowered devices without a dedicated graphics card.
