【犀牛鸟实战issue】 macOS support with custom_rasterizer for CPU

[liangxg787]

【问题描述】目前代码环境配置都是在CUDA环境中，如何在macos中运行Hunyuan3D-2.1
【期望改进】在macos中运行Hunyuan3D-2.1
【完成方式】给出环境配置文档和代码

Summary of Changes

1. Added README_for_apple_silicon.md with setup instructions for Apple Silicon.

2. Added demo_for_apple_silicon.py as a usage example on Apple M-series chips.

3. Added device parameter to gradio_app.py for hardware flexibility.

4. Added compile_mesh_painter_for_apple_silicon.sh script for compiling on Apple Silicon.

5. Introduced new CPU-specific scripts for building custom_rasterizer:

   • grid_neighbor_cpu.cpp
   • rasterizer_cpu.cpp
   • rasterizer_cpu.h
   • setup.py

6. Added device parameter to textureGenPipeline.py.

7. Added new parameter face_count in simplify_mesh_utils.py, compatible with the latest trimesh version. Because the trimesh==4.4.7 could not work on MacOS.

8. Added requirements_for_apple_silicon.txt for environment setup on Apple Silicon.

Testing

• Platform: Apple Silicon (Apple M-series chip)

Notes

1. If you encounter a segmentation fault, it might be due to insufficient RAM on macOS.

2. Running the rasterizer in Hunyuan3DPaintPipeline on CPU is significantly slower. It is recommended to either:

   • Use an alternative rasterization method (to-do), or
   • Run Hunyuan3DPaintPipeline on a GPU for better performance.

Can you tell me what Python version you're running to build this because I can't find release which satisfies both scipy 1.14.1 and bpy 4.0

Python 3.10.18

Then something has changed requirements since you made this pull request. The following was captured from 3.10.18

ERROR: Ignored the following versions that require a different python version: 1.16.0 Requires-Python >=3.11; 1.16.0rc1 Requires-Python >=3.11; 1.16.0rc2 Requires-Python >=3.11; 1.16.1 Requires-Python >=3.11; 1.16.2 Requires-Python >=3.11; 1.6.2 Requires-Python >=3.7,<3.10; 1.6.3 Requires-Python >=3.7,<3.10; 1.7.0 Requires-Python >=3.7,<3.10; 1.7.1 Requires-Python >=3.7,<3.10; 2.3.0 Requires-Python >=3.11; 2.3.1 Requires-Python >=3.11; 2.3.2 Requires-Python >=3.11; 2.3.3 Requires-Python >=3.11; 2.3.4 Requires-Python >=3.11

There is no available overlap between the python versions required by scipy and bpy.

I think you can try to remove the version number and then install scipy and bpy.

[PeteHaughie]

After removing the pinned version numbers I was able to install with 3.11.13 as scipy wants a higher version than 13.10 now.

I did get a segmentation fault on an M2 with 32GB though which came as a surprise.
