I came across this video on Vimeo the other day: https://vimeo.com/290181848
I was intrigued as to how this was achieved, and in my impulsive search for answers I came across photogrammetry and the point cloud that is generated from the process. I've concluded that this is how it was done.
I've since managed to produce my own point cloud scene through photogrammetry, and have been using Meshlab to visualise it.
The problem here is that I'm having trouble importing a coloured point cloud into Blender that also renders.
Importing a point cloud to Blender ignores colour (it shows as black), and doesn't show at all when rendering.
I've found an add-on that allows me to visualise a coloured point cloud (Add-on info can be found here), but it seems that I can only visualise the point cloud using this add-on. It doesn't show in the render. This isn't particularly helpful, as I can already do this using Meshlab.
I eventually found this blog post. It explains how to convert the PLY files to a modified PLY file that produces "splats" at each point.
Unfortunately, I'm not a programmer, nor do I have access to a windows computer in order the run the .exe file included in his Github repository.
At this point, it would appear that my only choice is to seek a windows-running PC to convert this file in order to achieve the desired effect.
A few questions:
- Do I appear to be on the right track?
- Do you feel that following the linked blog post will work?
- To your knowledge, is there a Mac-only way to do this?
- Is the process outlined in the linked blog post something that could be turned into a Blender add-on?
- Will there be a way to adjust the size of the points in the same way you can in Meshlab?
