3D对象-Polycount [英] 3D object - polycount

问题描述

您好！

我想在运行时获取3D模型的多边形数量. MehshGeometry3D类的TriangleIndices.Count是否表示多边形计数?我能正确理解吗?

如果是，那么Expression Blend 3似乎几乎是多边形数量的三倍-我导入的obj大约有30000多边形，转换为XAML的多边形现在已经接近90000(如果是TriangleIndices.计数可用于多边形计数).

在此先多谢！

问候

Hi there!

I want to get the number of polygons of my 3D model at runtime. Is TriangleIndices.Count of the MehshGeometry3D class representing the poly count? Do I understand that correctly?

If yes, then Expression Blend 3 seemed to nearly triple the amount of polys - my imported obj has around 30000 poly, converted to XAML it has nearly 90000 now (if TriangleIndices.Count can be used for poly count).

Thanks a lot in advance!

Greetings

推荐答案

TriangleIndices.Count将返回三角形索引的总数.          每个三角形均由3个索引值组成，因此三角形的计数将为三角形索引/3.

TriangleIndices.Count will return the total count of triangle indices.  Each triangle is made up of 3 index values, so the triangle count will be triangleindicies/3.
