SLAM System Pipeline

Our method performs real-time SLAM by fusing synchronized inputs from a multi-camera rig into a unified 3D Gaussian map. It first selects keyframes and estimates depth and normal maps for each camera, then jointly optimizes poses and depths via multi-camera bundle adjustment and scale-consistent depth alignment. Refined keyframes are fused into a dense Gaussian map using differentiable rasterization, interleaved with densification and pruning. An optional offline stage further refines camera trajectories and map quality. The system supports RGB inputs, enabling accurate tracking and photorealistic reconstruction.

Analysis of Single-Camera and Multi-Camera System

This experiment on the Waymo Open Dataset (Real World) demonstrates the effectiveness of our Multi-Camera Gaussian Splatting SLAM system. We evaluate the 3D mapping performance using three individual cameras, Front, Front-Left, and Front-Right, and compare these single-camera reconstructions against the Multi-Camera SLAM results.

The comparison highlights that the Multi-Camera SLAM leverages complementary viewpoints, providing more complete and geometrically consistent 3D reconstructions. In contrast, single-camera setups are prone to occlusions and limited fields of view, resulting in incomplete or distorted geometry. Our approach effectively fuses information from all three perspectives, achieving superior scene coverage and depth accuracy.

To add to the history, there was an official mobile version of Tomb Raider: Underworld developed by around the time of the original console release. This version featured 3D graphics, puzzles, and exploration, but it was designed for older feature phones with WAP portals. It is no longer available for modern smartphones. tomb raider underworld android game link download

Modern Android flagships (and even mid-range phones) are powerful enough to emulate PlayStation 2 or Wii versions of the game.

If you have a strong internet connection, you can stream the modern trilogy via cloud gaming services like Xbox Cloud Gaming or NVIDIA GeForce NOW directly to your Android browser or app.

The Internet Archive hosts thousands of old mobile games for preservation purposes. Search for . Look for files labeled .apk and accompanying .zip folders containing cache data (OBB).

Analysis of Single-Camera and Multi-Camera SLAM (Tracking)

In this section, we benchmark tracking accuracy across eight driving sequences from the Waymo dataset (Real World). MCGS-SLAM achieves the lowest average ATE, significantly outperforming single-camera methods.
