Technical Report: Virtual Xray imaging for higherorder finite element results
This work describes and demonstrates the operation of a virtual Xray algorithm operating on finiteelement postprocessing results which allows for higher polynomial orders in geometry representation as well as density distribution. A nested hierarchy of oriented bounding boxes is used for preselecting candidate elements undergoing a raycasting procedure. The exact intersection points of the ray with the finite element are not computed, instead the ray is discretized by a sequence of points. The elementlocal coordinates of each discretized point are determined using a local Newtoniteration and the resulting densities are accumulated. This procedure results in highly accurate virtual Xray images of finite element models.
