专家解读海军陆战队“万人千车”最大跨区训练
百度 新车的悬挂用的是前麦弗逊+后多连杆式的独立悬挂，虽然从结构上看，它的类型还是以偏向舒适性为主，但实际的表现却给我啪啪打脸，因为我在此之前，没有开过一款像10代雅阁这样，拥有如此扎实底盘，优异路感的本田车型，说白了它能让我不自觉的想把车开快，去体验驾驶的乐趣。
The knowledge of the numbers, formulas, shapes and quantities. In the computer graphics, almost exclusively linear algebra is being used.

Algorithm for cleaning non manifold meshes?
Assume you have a triangle set such that there is a sub-simplicial complex of your mesh (a sub mesh) that is manifold.
Is there an algorithm that can compute the maximal manifold submesh of the input ...

Numerically telling if a point in an SDF is a saddle point?
I am wondering if I can use some of the numerical operators (gradient, laplacian, divergence, mean curvature...) and apply it to a point on the 0 iso surface of an SDF in order to tell whether it is a ...
