I added a new PointCloudGeneration scene and script using a similar pointcloud generation code to RawPointCloudBlender.

@petpetpeter How does that differ from the existing raw point cloud generation example? Do you create a mesh from the points? An example screenshot or similar would be great

The existing PointCloudGenerator script creates a list of vertices no the button callback
and appends the vertex according to the depth value.

When using Raw Depth, I found that it crashes on my devices (Pixel4a and Mi 9) and seem to be very slow on a better smartphone according to #29 (comment)

from PointCloudGenerator.cs

The newly updated RawPointCloudBlender script buffers the vertices before updating the vertex.
This work fine on the mentioned devices.

from RawPointCloudBlender.cs

So, it would be great if the PointCloudGeneration Example uses a similar method.

I'm testing and reviewing this one. Thank you for the patience.

Hey petpetpeter,

Sorry for the late reply, as I could not get any point clouds from your PR on Wednesday and I tried again on this Friday, both using Pixel 4, Unity 2019.4.22f1.

For both tests, I copied the 4 files without any modification, then added opened scenes as the only scene to build. The update button shows, but I cannot get any feedback. In contrast, my raw point cloud scene runs when set as the only scene to build.

Sorry that I don't have much time to debug, as I have some life events next week. Would you please double check your PR and make sure it runs?

Cheers,
Ruofei

@ruofeidu My bad. I didn't copy the meta files so the script is missing from the inspector.

Now, I test by replacing the whole PointCloud folder from PR with the original andriod-sdk branch in a new project.

In case it is more convenient for you,
You can copy the PointCloudWithRawDepth scene and RawPointCloudGenerator.cs and set the inspector like this:

In PointCloudWithRawDepth scene

Sorry for your inconvenient, Please take your time 👍

Thank you petpetpeter for the update! I'll test it early next week :) Have a great weekend!
