The length of the ray within the box has no influence and so the assigned colour for the rays (1) and (2) will be the same at the camera sensor. For both rays this is simply done by blending the initially assigned colour (red) with the blue colour of the surrounding box, due to its opacity (see formula above). Top: the colour on the sensor is only determined by the two intersections (a) and (b) for the upper ray (1) and by the two intersections (c) and (d) for the lower ray (2). UsingĮxample data sets that we have generated and preprocessed using Skua-Gocad, we will explain the workflow and discuss theĭifferent options and problems to generate such visualizations.Ĭomparison of primitive-based rendering (top) and the volume rendering approach (bottom). Volume visualization could be augmented with the information on the uncertainty in the geological model. In order to express the uncertainty in data and models, mostly from other scientific disciplines, and show how our suggested We will then provide a short review of which visualization methods are available Made more intuitive using volume rendering. Outline the problems we see with the different visualizations, and show how the visualization could be improved and be Options for certain geological models which are part of the standard geological modelling packages, such as Gocad or Petrel, Structures in the subsurface are known with a precision of up to a centimetre. Thus, such visualizations give the impression that the geological Very closely without changing the quality of the representation. Most commonly visualised as vector graphics, for example by using triangulated surfaces, which allows users to zoom in That is inherent in these 3D geological models, due to, e.g., scarce data and interpretation ambiguities. Further, the visualization should make the users aware of the uncertainty In order to allow these users to interpret this information meaningfully, clear and intuitiveģD visualization plays an important role.

The corresponding 3D models are made ever more widely available to general users, ranging from the interested public to politiciansĪnd decision makers who might be economists or lawyers, most of whom have received no specific professional training 3D geological modelling is increasingly becoming a standard tool among geological survey organizations.
