Appearance

Modelling of organ appearance in the virtual scene is the next element of the scenario generation process. As stated in [116], realism of rendered scenes demands complexity, or at least the appearance of complexity. Therefore, we strive to enhance the visual richness of the surface triangle models generated in the previous step by adding further detail. The application of surface textures to geometric models – also referred to as texturing – is currently one of the key techniques in interactive computer graphics, to add complexity and thus realism to visual rendering. With this approach, the representation of minute object detail with geometric information can be avoided. Moreover, texture mapping requires only little additional computational effort in the rendering process.
