After updating pyenv (such as through a brew upgrade), run pyenv rehash to reset the shim routes. Otherwise, you get errors like:

/Users/[USER]/.pyenv/shims/python2: line 21: /usr/local/Cellar/pyenv/1.2.4/libexec/pyenv: No such file or directory

• Import the PCX Unity Package.
• Drag a PLY point cloud into the project. The plugin will automatically convert it to a GameObject. This takes some time during which Unity will hang. The resulting GameObject will be in the same directory as the PLY.
• Add the GameObject to your scene.
• If the point cloud is a right-handed coordinate frame, negate the scale of the Z axis to flip it to Unity's left-handed system. This parameter is accessible through the Transform component on the GameObject.
• It may also be necessary to rotate 90 degrees around an axis depending on which axis is "up" in the point cloud coordinate frame.

• Install: brew install pcl
• Get install location: brew info pcl
• Copy pcl_viewer into the path: cp $(PCL_INSTALL_DIR)/pcl_viewer.app/Contents/MacOS/pcl_viewer /usr/local/bin
• Convert PLY to PCD: pcl_ply2pcd [INFILE] [OUTFILE]
• View the point cloud in pcl viewer with point picking: pcl_viewer -use-point-picking [PCD_FILE]
• To get the coordinates of a point, “SHIFT+CLICK” on a point. The coordinates are printed in the launching terminal.

# When you receive "warning: null character(s) ignore", there is a null byte hidden number in the source code. 
# This is likely the result of creating a file in Visual Studio which defaults to UTF-16LE and trying to read 
# it back as UTF8. 

# To check text encoding of the file, run the following and retrieve the `charset`
file -I [FILE]

# To convert the file to UTF8 (or any other encoding)
iconv -f [CURRENT_ENCODING] -t UTF8 [FILE] > temp
mv temp [FILE]
