How to visualize the large scale mesh map in real time? Are GPU and OpenGL used?

Looking forward to your response.

We don't use GPU in our ImMesh, which achieves real-time performance on just a CPU-only platform. For visualization, we use OpenGL for rendering.

Is GPU necessary or not? It depends on the scale of your maps. For non-large-scale mapping (e.g., total traveling length < 1 Km), the GPU is not necessary. On the contrary, rendering the map with a GPU indeed improves the rate of previewing.
