Abstract [en]

Direct Volume Rendering of Finite Element models is challengingsince the visualisation process is performed in worldcoordinates, whereas data fields are usually defined overthe elements’ material coordinate system. In this paper wepresent a framework for Direct Volume Rendering of FiniteElement models. We present several novel implementationsvisualising Finite Element data directly without requiring resamplinginto world coordinates. We evaluate the methodsusing several biomedical Finite Element models. Our GPUimplementation of ray-casting in material coordinates usingdepth peeling is several orders of magnitude faster than thecorresponding CPU approach, and our new ray interpolationapproach achieves near interactive frame rates for high-orderfinite element models at high resolutions.
