Features

• Render Gaussian Splat .ply Files: Visualize complex point cloud data using Gaussian splatting.
• Selective Splat Removal: Easily remove splats that are not needed or are incorrectly placed.
• Real-time Editing: Utilize OpenGL for fast rendering and interactive manipulation.

Build Instructions

Requirements

• CMake 3.10 or higher
• OpenGL development libraries
