EFFICIENT VISUALIZATION OF OBJECT PROPERTIES USING VOLUME RENDERING

摘要

A method for the visualization of an object using simulated radiation includes using a representation of the object, in which values of a variable that characterizes the object are given at spatial points in the object. A first ray is generated to determine a pixel color value assigned to a pixel for a two-dimensional representation of the object. The first ray is propagated through at least a part of the object. The method also includes determining, step-by-step, values of a variable on the first ray and detecting a surface of the object using the values determined on the first ray. At least one second ray is generated for determining a quantitative value that characterizes a property of the object, and the at least one second ray is propagated away from the surface, through at least a part of the object. The method also includes determining, step-by-step, values associated with the variable on the at least one second ray, determining the quantitative value that characterizes the property of the object using the at least one second ray, assigning a color value in accordance with the quantitative value, and using the color value to determine the pixel color value.
