APPARATUS FOR, AND METHOD OF, RENDERING IMAGE DATA |
摘要 |
Image rendering apparatus for rendering an image from a set of image data representing a volume, the apparatus comprises a rendering unit configured to perform a sampling process that comprises determining values of opacity for a plurality of sample positions along a specified path through the volume; at least one of a) determining values of colour/grayscale for the plurality of sample positions along the specified path, b) determining gradient values for a plurality of gradient positions along the specified path; and determining whether there is a transition to or from a high opacity state, and if there is a transition to or from a high opacity state modifying at least pad of the sampling process, wherein the rendering unit is further configured to process the determined values of opacity, colour/grayscale and/or gradient to determine a pixel value for a pixel of the image. |

1. Image rendering apparatus for rendering an image from a set of image data representing a volume, the apparatus comprising:
a rendering unit configured to perform a sampling process that comprises:
determining values of opacity for a plurality of sample positions along a specified path through the volume;at least one of a) and b):
a) determining values of colour/grayscale for the plurality of sample positions along the specified path;b) determining gradient values for a plurality of gradient positions along the specified path; anddetermining whether there is a transition to or from a high opacity state, and if there is a transition to or from a high opacity state modifying at least part of the sampling process, wherein the rendering unit is further configured to process the determined values of opacity, colour/grayscale and/or gradient to determine a pixel value for a pixel of the image. |
