摘要

介绍了两种新的逼近法线的方法，即通过推进立方体等表面来实现体积可视化。该方法比简单的中心差分梯度的标准方法使用高阶近似。新的近似方法对等值面渲染的影响也通过对已知最佳渲染的场景进行定量像素级比较来考虑。

Evaluation of high order approximating normals for Marching Cubes

Two new approaches for approximating normals for volume visualization by marching cubes isosurfacing are introduced. The approaches utilize higher order approximations than the standard approach of simple central differencing gradients. The impact of the new approximation approaches on isosurface renderings are also considered by quantitative pixel-level comparisons on scenes for which optimal renderings are known.
