4. Session 4 Software Installation
The best way is to follow the tutorials at GitHub:
- Download and install PuMA: https://github.com/nasa/puma
- Documentation: https://puma-nasa.readthedocs.io
- Community chat: https://gitter.im/puma-nasa/community...
- Online tutorials: https://colab.research.google.com/git...
Session 5 PuMA Workshop 2021 - Image Processing in the PuMA GUI
"""shell
pumaGUI
"""
进入GUI界面
- 8 bit tiff 3D image is acceptable for GUI import using
import 3D Tiffor just drag and drop.
默认灰度范围为0-255.分割的图像只有0-1，需要点击Rescale Vis缩放渲染范围。
- 支持（双）阈值分割，3D Render用的是PyVista。
- 当前支持生成随机模型（v3）
-
可以将模型导出为watertight的stl模型

Software operation
视频第23分钟开始：
Session 8 PuMA Workshop 2021 - pumapy: Introduction and Setup
windows下pip 安装尝试不成功，最终还是使用了conda
conda activate puma
conda create -y --name puma -c conda-forge puma
然后在PyCharm中选择conda，环境选择puma。
使用pyvista在numpy和vtk数据类型转换是可能会报错，因为numpy已经废弃了numpy.bool类型，需要在PyVista中注释掉该行。
