Open3D是一个开源库,支持快速开发处理3D数据的软件。Open3D后端是用C++实现的,经过高度优化并通过Python的前端接口公开。Open3D提供了三种数据结构:点云(point cloud)、网格(mesh)和RGB-D图像。对于每个表示,open3D都实现了一整套基本处理算法,如I/O、采样、可视化和数据转换。此外,还包括一些常用的算法,如法线估计...

ax = fig.add_subplot(111, projection='3d') Output: Here we are first creating a figure of size 4 inches X 4 inches. We then create a 3-D axis object by calling theadd_subplotmethod and specifying the value ‘3d’ to theprojectionparameter. ...
Houdini有三种内置语言:表达式、vex、python。 【**表达式】**Houdini的强大是建立在丰富的节点基础上的,通过节点的逻辑组合,可以幻化出千变万化的效果,而节点的参数控制可以完全由表达式进行设置,这是使用表达式的主要场合。利用表达式,我们还可以实现跨模块控制。
deform_random_grid(X, sigma=25, points=3, rotate=30, zoom=1.5)Note that the output shape remains the same. The mapping of the input to the output is rotated within the given output frame.Rotate and zoom can be combined with the crop argument. In that case, the scaling and rotation ...
