Jump into the world of 3D visualization with our comprehensive guide on Gaussian Splatting! This 30-minute tutorial is packed with invaluable insights on capturing and training 3D Gaussian Splats right from your PC. Discover how to seamlessly use SIBR viewers and NerfStudio to view your outputs, even if you're working with an older graphics card like the 1080ti. My unique workaround ensures you won't face any compatibility issues. This video is perfect for enthusiasts at any skill level - all you need is a dash of positivity! Whether you're a seasoned pro or just starting, join me in unlocking the potential of Gaussian Splatting on any setup.

🚨▶ Download Git - https://git-scm.com/
1️⃣▶ Check Your GPU's Compute Capability - https://developer.nvidia.com/cuda-gpus
🔗▶ Gaussian Splatting GitHub - https://github.com/graphdeco-inria/gaussian-splatting

======FIX YOUR SIBR VIEWERS=======
You need to change 2 files in SIBR_viewers folder to fix it

1. SIBR_viewers\extlibs\CudaRasterizer\CudaRasterizer\CMakeLists.txt

Change line: set_target_properties(CudaRasterizer PROPERTIES CUDA_ARCHITECTURES "70;75;86") To: set_target_properties(CudaRasterizer PROPERTIES CUDA_ARCHITECTURES "60;70;75;86")

2. SIBR_viewers\src\projects\gaussianviewer\renderer\GaussianView.cpp

Remove code on line 337*-339* (where the code is actually listed)

:
if (prop.major - 7)
{
SIBR_ERR -- "Sorry, need at least compute capability 7.0+!";
}
:

3. Rebuild the viewers as described in the Git
