Rendering red screen
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!
Hi, thanks for raising the issue. Have you tried moving around in the scene? If the initial camera position happens be inside a large read Gaussian, this could happen. Were you able to open other ply files with the latest version? What about with previous commits? If this line remains commented, I can't think of what might have caused this. The ply file would be very helpful if it could be provided.
@shg8 I wound up being able to open a flowers model from the "official link" mentioned here: https://github.com/limacv/GaussianSplattingViewer/tree/main?tab=readme-ov-file#usage
I will look into getting the ply file(s) we have. Thanks!
I am getting the same issue on my Mac with the bicycle scene :

I got it working on the files in the point cloud folder. those were actually trained on the sfm data , I was previously trying with the input file . Here is the result :
