We render a large number of Billboards via CZML wherein the Billboard image is provided via the texture atlas. From CZML we are able to specify scale, label, and position information (etc.).
Although I have read the tutorial on 3D models, investigated the Sandcastle examples, and run a simple test to include a 3D model into our scene, I’m not completely putting together how we would use these models instead of Billboards.
I would assume that the CZML we are using does not have to change except for the “billboard” attribute. In its place, do we specify “model” instead? If so, can we add 3D models to a texture atlas of sorts and specify the index via CZML? Furthermore, the 3D model examples I’ve seen appear to handle scaling by distance automatically. Is this true? Right now we are using a NearFarScalar to scale our Billboards.
Thanks for any hints or suggestions that might help put the pieces together.
