shg8 / 3dgs.cpp Goto Github PK

Thanks for this good project! I have to say that I have successfully run the project with my data on Release Mode:

But on Windows platform with (MSVC 2022 buildtool), the Debug mode will cause the linking issue:

which is quite strange. Any suggestion?
On the other hands, the profiler sames not meet the diagram size (I guess?), because the diagrams crowed on the right side:

(This data is of a black background, don't worry about the result displayed)

Any suggestion about that?

Anyway, this is just a little "bug" I have encountered, so I would like to share and report it.
Thanks for the contribution of such a great project :-). Best!

hi， thank you for your sharing code, i wonder can this project run in android platform such as Quest or mobilephone？

Could you add a trackbar control mode to this great viewer, just like meshlab~
The default mouse and keyboard control modes are a bit uncomfortable to use now :(

Hi, I have find some problem with Gaussian instantiation out of memory.

First time, I run a ply file ~2.1GB, and it worked well.
GPU memory usage went to ~8.5GB at first, then went to 9.4GB when the render result showed.

The next time, I run a ply file ~500MB, which is an edited version of the first file, by deleting some 'fog' points.
GPU memory usage also went to ~8.5GB at first, but then it came out Gaussian instantiation out of memory.

Why an edited small ply file causes out of memory?
The graphic card is Geforce RTX 2080 Ti 11GB.

Thanks.

I suggest to rename the executable file on windows as 'vviewer.exe'. So it can be run without changing anything. Vviewer sounds a nice name for a Vulkan viewer.

Hi there, I came across this project from reddit. I am trying to compile this project for macOS and also visionos to test on my vision pro.
I have install Vulkan SDK

(base) ➜  3DGS.cpp git:(main) ✗ ls /Users/xuhao/VulkanSDK/1.3.275.0
Applications        InstallationLog.txt MaintenanceTool.dat VERSIONS.txt        install_vulkan.py   macOS               tvOS                vulkan.7z
Helpers             Licenses            MaintenanceTool.ini components.xml      installerResources  network.xml         tvos.7z
INSTALL_BOM.json    MaintenanceTool.app README.txt          iOS                 ios.7z              setup-env.sh        uninstall.sh

However, when build this project with

cmake -DCMAKE_BUILD_TYPE=Release -DVULKAN_SDK="/Users/xuhao/VulkanSDK/1.3.275.0" -S ./ -B .\VulkanSplatting\build

or

cmake -DCMAKE_BUILD_TYPE=Release -DVULKAN_SDK="/Users/xuhao/VulkanSDK/1.3.275.0/macOS" -S ./ -B ./VulkanSplatting/build

It will come with

(base) ➜  3DGS.cpp git:(main) ✗ cmake -DCMAKE_BUILD_TYPE=Release -DVULKAN_SDK="/Users/xuhao/VulkanSDK/1.3.275.0/" -S ./ -B ./VulkanSplatting/build

Which path should I use?

Good afternoon! Thank you for the amazing 3DGS.cpp project. I have some background with WebGPU and basic TensorFlow but am generally still learning graphics programming and machine learning concepts.

I have an issue that may be related to my incorrect usage or settings, so my apologies ahead of time. However, the issue is pictured below:

I tried the nightly build as well 3 different builds at various stages in the commit history, but the latest seems most stable. Yet it is only giving a red screen.

I am able to open schoolbus.ply in another Python-based viewer. The file is binary (text header, binary body) as required.

I have a fresh installation of Vulkan and all the needed dependencies, and I am able to run Vulkan Cube, so it seems that Vulkan is working properly. If you'd like to examine schoolbus.ply, I could probably ask my client if that is okay!

Thank you for your time!

Hello, this is a really great job for me! But I'm having trouble reading the source code, can you explain it to me? I think sort.comp needs to be sorted according to depth, but I didn’t find the part that uses depth sorting. I only saw the code that groups the tiles together in one tile. Can you help me answer it? Thank you very much.

I built the viewer and tried to use it to load output of original 3DGS and got this error message:
