我想重新创建一个覆盖在T1.mgz上的FreeSurfer pial / white表面的Web版本,类似于https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/PialEdits_freeview的第一个freeview图像。使用XTK我可以使用来自Othographic Projection in XTK的建议得到一些提示。我用来创建图像的代码(以及多次尝试的kruft)位于图像下方。
这是否可以使用XTK,还是应该切换到AMI.js(其路线图上有freesurfer曲面和MGZ文件格式但未实现)?
在任何一种情况下,都会赞赏指向如何实现这一点。
感谢。

您现在可以在AMI中执行此操作(感谢您的PR:https://fnndsc.github.io/ami/#viewers_quadview)
显示网格和平面之间的交集
后处理交叉点以显示轮廓。
有不同的技术可以显示网格/平面交点:
所有这些技术在计算上都很昂贵,需要3个渲染才能显示1个网格的轮廓,并且可能有更好的方法但不确定什么是最佳选择。
