    摘要: The present embodiment relates to a renderer and an interactive method for image editing of medical 3D anatomical data. The method includes receiving a dataset with volumetric image data, which have been acquired from an image acquisition modality, and providing a signed distance field data structure of the received dataset. Further, editing operations are received from a user interface for editing at least a part of the provided signed distance field data structure. A visualization of the editing operations is calculated and displayed on a display.

    摘要: A three-dimensional object is provided within a light probe, at least one intensive light source of the light probe is detected and selected. Furthermore, a multiplicity of rays are simulated for a respective visualization pixel. For a respective ray entering into an object volume, i) a scattering position is determined, ii) a scattering direction is selected, with a decision being made depending on a first random process as to whether the ray is scattered in the direction of the intensive light source or in a scattering direction to be selected depending on a second random process, and iii) the ray is scattered in the selected scattering direction. Steps i) to iii) are repeated until the ray is absorbed in the object volume or emerges from the object volume and impinges on the light probe.

    摘要: The inner volume of an inhomogeneous three-dimensional object is visualized by a plurality of simulated visual rays. For a respective visual ray entering the object volume, i) a scatter position is determined along the visual ray, ii) a scatter direction is selected in dependence on a random process, and iii) the visual ray is scattered at the scatter position in the selected scatter direction. Steps i) to iii) are repeated until the visual ray is absorbed in the object volume or exits the object volume, wherein the exiting visual ray is incident on an illumination source and, in dependence on a brightness and/or color value of the illumination source, an illumination contribution of the visual ray to a respective visualization pixel is ascertained.
