Thanks to the developers and the community. I enjoy programming as a hobby. I wrote an article about Panda3D in the famous programming magazine “Nikkei Software” in Japan.
Download the elevation data from the Geospatial Information Authority of Japan website in Japan. Panda3D places a cube at a location in the elevation data. The color of the cube was changed depending on the altitude. You can rotate the camera to look at it from a different angle, submerge the land into the sea, or float it.
Unfortunately, there is only Japanese explanation. I’m sorry I’m not good at English. I will continue to enjoy programming. Thank you
