Overview

Installation instructions for setting up a GCP VM with Tensorflow-gpu.

Select Compute Engine > VM Instances > Create Instance.
Specify Name, Region, and Zone. Note, the zone must support GPU instances.

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.

	# 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
