CONNECTIVITY DEPENDED GEOMETRY OPTIMIZATION FOR REAL-TIME RENDERING

Disclosed is a computer-implemented method for visualising/rendering a computer model, the computer model comprising a plurality of components wherein the method comprises: storing a plurality of parts of at least one of the plurality of components, each part including geometry information for visualising/rendering the part, storing information indicative of the position and orientation of a plurality of components in a coordinate system, determining a spatial relationship between individual components, determining for the at least one component a number of stored parts to use for visualising/rendering the component, based on the determined spatial relationship between the individual components. By using the spatial relationship between the components to determine the number of parts to use for visualising/rendering a component, knowledge about the geometry of individual components and the connections of the components with other components can be used to find hidden parts that can be removed.
