We are looking into the migration of a product from Google Earth to Cesium. Part of the product involves moving a ship’s model in real time.
I have set up a small trial to move the ship at the clock ticks. If I use the Cesium_Ground.gltf model from the sandbox, the animation is very smooth; the frame rate is 40-50 FPS (according to the Cesium inspector).
I have also converted an existing ship model from .dae to .gltf with the offline conversion tool, the model is almost 9MB (vs. about 1MB for Cesium_Ground.gltf).
If I use this model in the same trial, the rate drops to 4FPS and the animation is not very smooth (i.e. not good enough for our purpose).
Can this be caused by the larger model, or is there something wrong with the model itself? (Unfortunately I can’t publish the model here).
Or are there larger .gltf models available somewhere that I could try out.
Thanks, Willem van der Gugten
