Below are videos that makes use of gVXR. If you made your own video making use of gVXR, please let me know so that I can add it to the list.

  • LabCT with gVXR, CIL and Unreal engine

    This video was made as part of a MSc dissertation on the integration of X-ray simulation into the popular game engine called Unreal Engine. The user evolves in a 3D virtual environment, just like in a video game. It allows the user to use a fully functional X-ray CT scanner to image the interior of an object. It features gVirtualXray (https://gvirtualxray.sourceforge.io/) for the simulation and core image library (CIL) (https://ccpi.ac.uk/cil/) for the reconstruction.

  • WebCT, a Quick Introduction

    WebCT is an interactive Web UI for X-ray CT with real-time results. You can find it at https://webct.io/ It is built on the top of gVirtualXray (https://gvirtualxray.sourceforge.io/) for the simulation and core image library (CIL) (https://ccpi.ac.uk/cil/) for the reconstruction.

  • gVirtualXRay at IBFEM-4i (Sept 2018)

    A replay of the talk I gave at IBFEM-4i (https://ibfem.co.uk/2018/) in Sept 2018 on the use of the gVirtualXRay library applied to micro-tomography by synchrotron radiation in material science. The slides are available at http://gvirtualxray.sourceforge.net/pdf/Slides_IBFEM_4i_2018.pdf The talk starts with some backgrounds, followed by the simulation model implemented in OpenGL/GLSL. Then the validation of the library is briefly discussed. Application examples are then discussed. The Python implementation of a case study micro-tomography of a tungsten fibre is then discussed. It includes evolutionary computing using X-ray simulation in the objective functions.
