Progressive refinement for texture-based volume rendering |
摘要 |
A method for rendering a two-dimensional image comprising: (a) obtaining a first three-dimensional set of data for a relatively high quality image; (b) generating a second three-dimensional set of data for a relatively low quality image from the obtained three-dimensional set of data; (c) rendering a relatively low quality two-dimensional image from second three-dimensional set of data; (d) rendering a first portion of a relatively high quality two-dimensional image from a first portion of the first three-dimensional set of data; (e) blending the rendered low quality two-dimensional image with relatively high quality two-dimensional image; (f) rendering a second portion of a relatively high quality two-dimensional image from a different portion of the first three-dimensional set of data; and (g) blending the rendered low quality two-dimensional image from second three-dimensional set of data with relatively high quality two-dimensional image from the second portion of the first three-dimensional set of data. The process repeats until the entire image is rendered.
