Been doing a lot of stuff with point clouds lately, so I figured I'd show some workflows. :)
The stream will stay up as an archive for those can't make it!

Hey Mantissa, thank you so much for the amazing tutorials (plural!). I do have a question and I didn't understand something during the filming process: My final product is a rendered point cloud as a printed image from a position of a forest situation. I've seen some parts in your tutorial which have this mood. The explanation with the tree was fully understandable with the walk around, how does it work with the walktrough? Did you keep filming slowly up, left and right to get as much information as possible? Or did you just walk straight? Thanks for your feedback, it would be extremely helpful to me and an artistic project I am working on! Best Matthias

The resulting point cloud you get really depends on your camera path. If you circle around an object, you'll get a 360 view of it in your point cloud. If you walk a straight path, you'll just have the view from that path. I do that because I know I'm following a similar path with my CG camera so I can get away with it. You can have a look at a whole bunch of point clouds I've created here and use them for anything: archive.org/download/mantissa-pointclouds

@@MidgeSinnaeve Wow, thank you so much for your answer - I really appreciate it! I'll take a close look at this, I bought the Point Visualizer app and that's something. Unfortunately, certain settings are different like what you show here with Points from Mesh I can't see any rendering and vertices and exporting to Alembic in Blender doesn't work either/not progressing at all. I'm still looking for the right format, including the data size, in order to have fine points. I've been working with Metashape for a long time and need Blender as an intermediate step to transfer the Point Cloud to Cinema 4D and then make very large format prints, not animation. If you have another tip about this, I would be very happy and thanks again for your great tutorials and humor 🙂. (Ps: I work with a 3970 Threadripper, 128GB Ram and two RTX 5000)

it would be a lot of effort, but solid state lidar sensors have gone down in price a lot over the last years, for a university project i used a livox horizon (240k points/s), and i know its possible to calibrate it to a camera to capture color point clouds, probably too much trouble compared to the photogrammetry method, but since they can have a lot of range (ours had 260m) it would allow some crazy captures

I bought the PCV addon specifically to convert some meshes, but the color data doesnt come through from the texture. I guess Im missing some step but been stuck for a minute! Any ideas? does the mesh have to be a .ply or can we use anything?
@MidgeSinnaeve
@MidgeSinnaeve 6 ай бұрын
I'm using .ply formatted point clouds that I'm importing in to Blender. To get the color from a mesh you would either copy the UV's or convert them to Vertex Colors. With PCV, you should be able to use Mesh Surface to generate points on the surface. Have you had a look at the documentation? It's pretty good: jakubuhlik.com/docs/pcv/docs.html

Hi. Is there any way to animate the 3d mesh tho? and have an animated point cloud result?
@MidgeSinnaeve
@MidgeSinnaeve Жыл бұрын
Of course, You could animate it with shape keys, modifiers of geometry nodes, to name just a few options. You want to animate it before the geometry nodes modifier though, so you're just affecting tje underlying vertices of the mesh. I've used modifiers a lot to animate some of these.

Amazing tutorial, man! What lens do you use to film the forest scenes? I only own a 40mm prime, would it be appropriate or do I need a wider lens?
@MidgeSinnaeve
@MidgeSinnaeve Жыл бұрын
So that question kinda depends on your camera. On full frame, I think it might work, anything else I doubt it. My camera has a Super 35 / APS-C sensor and I've mostly been using a 14mm, so that would equal 21mm on Full Frame. I would honestly just give it a go and see what the results are. If you know someone that has a go pro or something similar, maybe try that as well?

@@MidgeSinnaeve I hear you. RC was still expensive up until recently when Epic got involved. I think the PPI model is probably also off-putting to a lot of users no matter how cheap it is. From what I can gather after reading all over the web, RC is apparently very quick at creating the point cloud and mesh but when it's buggy, then it's buggy as heck, and then artists like to fall back on other tools like Metashape, Meshroom, etc. Thanks again for sharing, and for your reply. Stay amazing!
