Method for visualizing an inhomogeneous three-dimensional object, which is represented by volume data, wherein a) the volume data indicates a density of the object to be imaged in an object volume, b) for a respective visualization pixel, a large number of visual rays (R1,...,R6) which are associated with the visualization pixel are simulated, wherein, for a respective visual ray (R1,...,R6) which enters the object volume, i) a scatter position is determined in dependence on the density along the visual ray (R1,...,R6), ii) a scatter direction is selected in dependence on a random process, iii) the visual ray (R1,...,R6) is scattered at the scatter position in the selected scatter direction, and iv) steps i) to iii) are repeated until the visual ray (R1,...,R6) is absorbed in the object volume or exits the object volume, wherein the exiting visual ray is incident on an illumination source (LP1,...,LP3, LS1, LS2) and, in dependence on a brightness and/or color value of the illumination source (LP1,...,LP3, LS1, LS2), an illumination contribution of the visual ray (R1,...,R6) to the respective visualization pixel is ascertained, wherein - a plurality of environment images (LP1,...,LP3) surrounding the object volume are provided as illumination sources, - a scatter type is associated with the visual ray (R1,...,R6), - at least one of the environment images (LP1,...,LP3) is selected in dependence on the scatter type of the exiting visual ray, - a point of incidence of the exiting visual ray on the environment image is ascertained, - the illumination contribution of the visual ray (R1,...,R6) is ascertained, in dependence on a brightness and/or color value at the point of incidence, specifically on the basis of the at least one selected environment image (LP1,...,LP3), and c) a statistical average is taken over the respective illumination contributions of the large number of visual rays (R1,...,R6) in order to ascertain a brightness and/or color value for the associated visualization pixel. a) the volume data indicates a density of the object to be imaged in an object volume, b) for a respective visualization pixel, a large number of visual rays (R1,...,R6) which are associated with the visualization pixel are simulated, wherein, for a respective visual ray (R1,...,R6) which enters the object volume, i) a scatter position is determined in dependence on the density along the visual ray (R1,...,R6), ii) a scatter direction is selected in dependence on a random process, iii) the visual ray (R1,...,R6) is scattered at the scatter position in the selected scatter direction, and iv) steps i) to iii) are repeated until the visual ray (R1,...,R6) is absorbed in the object volume or exits the object volume, wherein the exiting visual ray is incident on an illumination source (LP1,...,LP3, LS1, LS2) and, in dependence on a brightness and/or color value of the illumination source (LP1,...,LP3, LS1, LS2), an illumination contribution of the visual ray (R1,...,R6) to the respective visualization pixel is ascertained, wherein - a plurality of environment images (LP1,...,LP3) surrounding the object volume are provided as illumination sources, - a scatter type is associated with the visual ray (R1,...,R6), - at least one of the environment images (LP1,...,LP3) is selected in dependence on the scatter type of the exiting visual ray, - a point of incidence of the exiting visual ray on the environment image is ascertained, - the illumination contribution of the visual ray (R1,...,R6) is ascertained, in dependence on a brightness and/or color value at the point of incidence, specifically on the basis of the at least one selected environment image (LP1,...,LP3), and i) a scatter position is determined in dependence on the density along the visual ray (R1,...,R6), ii) a scatter direction is selected in dependence on a random process, iii) the visual ray (R1,...,R6) is scattered at the scatter position in the selected scatter direction, and iv) steps i) to iii) are repeated until the visual ray (R1,...,R6) is absorbed in the object volume or - a plurality of environment images (LP1,...,LP3) surrounding the object volume are provided as illumination sources, - a scatter type is associated with the visual ray (R1,...,R6), - at least one of the environment images (LP1,...,LP3) is selected in dependence on the scatter type of the exiting visual ray, - a point of incidence of the exiting visual ray on the environment image is ascertained, - the illumination contribution of the visual ray (R1,...,R6) is ascertained, in dependence on a brightness and/or color value at the point of incidence, specifically on the basis of the at least one selected environment image (LP1,...,LP3), and c) a statistical average is taken over the respective illumination contributions of the large number of visual rays (R1,...,R6) in order to ascertain a brightness and/or color value for the associated visualization pixel.
