Perception-based visual quality metrics are used in volume rendering. A perception-based visual quality metric is measured from one or more three-dimensional representations. For example, people tend to notice edges, so a numeric value representing the noticeable edges is calculated. The perception-based metric is used for developing volume renderers, calibrating across different renderers, calibrating across different rendering platforms, determining rendering parameter values as a function of rendering speed, selecting rendering parameter values for a given situation, providing a range of rendering options associated with gradual perception changes, and/or combinations thereof. The perception-based visual quality metric provides a quantifiable representation of importance to the user for a given application, assisting optimization of volume rendering.
