1. A visualization system for rendering images from a multi-dimensional data set, comprising: a display with a user input in communication with an interactive visualization system, the user input including a direct electronic priority control input that allows a user to affirmatively designate at least one explicit prioritized feature in an image rendered from a multi-dimensional image data set and, in response, the interactive visualization system electronically assigns a viewing parameter priority for subsequent visualization for the affirmatively designated at least one explicit prioritized feature, wherein the at least one prioritized feature is automatically electronically rendered with high or full quality in different interactively requested rendered images of the image data while other non-prioritized features are rendered at lower quality.
