Update

• Code for Diff-rasterization(w/pose --> 4✖️4 Transformation Matrix T)
• Code for RGBD-SLAM
• Code for Evaluation

Submodule

We have proposed a comprehensive mathematical theory on derivatives w.r.t. pose in 3D Gaussian splatting framework. Additionally, we have developed a specialized CUDA framework tailored for the SLAM task, decoupling the tracking and mapping components. For more details, please refer to the provided diff-gaussian-rasterization.
