Large language models have become a potential pathway toward achieving
artificial general intelligence. Recent works on multi-modal large language
models have demonstrated their effectiveness in handling visual modalities. In
this work, we extend the research of MLLMs to point clouds and present the
LAMM-Dataset and LAMM-Benchmark for 2D image and 3D point cloud understanding.
We also establish an extensible framework to facilitate the extension of MLLMs
to additional modalities. Our main contribution is three-fold: 1) We present
the LAMM-Dataset and LAMM-Benchmark, which cover almost all high-level vision
tasks for 2D and 3D vision. Extensive experiments validate the effectiveness of
our dataset and benchmark. 2) We demonstrate the detailed methods of
constructing instruction-tuning datasets and benchmarks for MLLMs, which will
enable future research on MLLMs to scale up and extend to other domains, tasks,
and modalities faster. 3) We provide a primary but potential MLLM training
framework optimized for modalities' extension. We also provide baseline models,
comprehensive experimental observations, and analysis to accelerate future
research. Codes and datasets are now available at
