panda3d how create planet with relief ?

thank you for your reply.

thin, I thought panda3d could make me a spherical plane natively :cry:
Iā€™m starting with panda3d and i have no idea how to do it :neutral_face:

For physic engine, i can use Bullet, thank you for your advice

Looking at the documentation of Bullet, for handle collision in a ShaderTerrainMesh i must use BulletHeightfieldShape.
i found example here :
