摘要： The rendering pipeline is divided into multiple components or modules in a scene graph based visual programming environment. Different stages of the rendering pipeline, such as data conversion, transform function, shading, and rendering, are grouped into independent conceptual modules, and each module is implemented by separate nodes in a scene graph. The user may select different nodes belonging to different modules for inclusion into the scene graph to program the rendering pipeline. The visual program is implicitly compiled and run using an application programming interface for hardware acceleration.

摘要： A method for volume rendering a digitized image includes providing a pair of adjacent 2-dimensional images of texture data, identifying a plurality of polygons extending in slabs between said adjacent two dimensional textures, and finding the first and last visible voxel for the data rows and data columns of each said polygon. The minimum and maximum bounds of each data row and for each data column are determined, those data rows and data columns that do not contain any visible voxels are marked as invisible, and the polygons are rendered along a direction orthogonal to a dominant viewing direction, wherein rendering of texture data is restricted by the outer bounds of polygons that are trimmed to the minimum and maximum bounds of two neighboring data rows or data columns, and wherein those data rows and data columns marked as invisible are skipped.

摘要： Disclosed is a method and apparatus for computing the shading of a volume. A slice of the volume is rendered along a half-angle direction that is between a light direction and a view direction. A slice of the volume is then rendered along a light direction to assimilate shadow information of the slice in a shadow buffer. The shadow buffer is bled orthogonal to the light direction to shade the slice.

摘要： At least one embodiment of the present invention relates to a method and an apparatus for visualizing 3D image data from tomographic imaging modalities using a rendering technique in which every pixel is calculated by integrating or summing along respectively one ray through a volume surrounded by the 3D image data. In the method, a peeling function is additionally introduced into the integration or summation, by which, in the integration or summation, the 3D image data on the respective ray only contributes with its full data value to reducing the optical transparency beyond a prescribable value of an optical skin depth. The peeling function is selected such that, in a transition region before the prescribable value of the optical skin depth is reached, the 3D image data on the ray still contributes to reducing the optical transparency with a fraction of its full data value such that there is a smooth profile, generated by the peeling function, when an outer layer is peeled off. The method and the associated apparatus make it possible to avoid image artifacts such as pixel flickering during volume visualization.
