论文摘要
我们试图用一组均匀间隔的谱带覆盖一个参数域，这些域根据密度字段进行数字和宽度。我们提出了一种隐式程序算法，该算法会生成从像素着色器的带状图案，并实时适应对控制字段的更改。每个频段是由整数识别的。这允许多种纹理效果，包括指定每个频段中的呈差外观。我们的技术还提供了尺度的渐进级别，从而避免了典型细分方法线数量的突然加倍。这是绘制带，绘制分裂和合并曲线以及绘制间隔的流线的一般方法。使用这些碱基成分，我们演示了各种纹理效应。
We seek to cover a parametric domain with a set of evenly spaced bands which number and widthvaries according to a density field. We propose an implicit procedural algorithm, that generates theband pattern from a pixel shader and adapts to changes to the control fields in real time. Each band isuniquely identified by an integer. This allows a wide range of texturing effects, including specifying adifferent appearance in each individual bands. Our technique also affords for progressive gradationsof scales, avoiding the abrupt doubling of the number of lines of typical subdivision approaches. Thisleads to a general approach for drawing bands, drawing splitting and merging curves, and drawingevenly spaced streamlines. Using these base ingredients, we demonstrate a wide variety of texturingeffects.
