sphere with texture and heightmap ?

Code Snippets
1

Hello, with Panda3D can i create platene ?

If you are away from the world I would like a simple sphere with a texture
But if I am close I would add relief, using a heightmap I guess ?
can i apply heightmap relief in sphere surface ?

Yes you can create planets with panda!

The trick I use is I don’t use a sphere but a cube. I use a shader to morph the cube into a sphere. I then apply a height map to the sides of the “cube” for my terrain.

There are other ways to do it too.

if i use cube, physic and collision are cube not sphere ?

i see example here :

But i want to not use egg model for “simulate” sphere.

for shere i see this :
panda3d.org/manual/index.ph … _Texturing

but i have not code example :frowning:
i want to like this : youtube.com/watch?v=345lLB0hhe8

people to help me?

Here is a script to help you make any shape in panda.

Here is some example code (I’m doing this from memory so it might be wrong):

from procedural import IcoSphere
planet = Icosphere(radius=1, subdivisions=3)
planet.repartentTo(render)

thank you but your code not work for me.

I have a blank gray window

this is my code :

import direct.directbase.DirectStart
import procedural

model = procedural.IcoSphere(radius=1, subdivisions=3)
model.reparentTo(render)
base.run()

how to apply terrain to my sphere ?

from __future__ import print_function

import os
import sys
from panda3d.core import Vec3, load_prc_file_data, ShaderTerrainMesh
from direct.showbase.ShowBase import ShowBase


from panda3d.core import *

import threading
from threading import Thread
import procedural


class Application(ShowBase):
    def __init__(self):
        ShowBase.__init__(self)
        model = procedural.IcoSphere(radius=1, subdivisions=3)
        model.reparentTo(self.render)
        
        heightfield = loader.loadTexture("resources/heightfield.png")
        
        terrain_node = ShaderTerrainMesh()
        terrain_node.heightfield = heightfield
        terrain_node.target_triangle_width = 6.0
        terrain_node.generate()

        terrain_n = model.attach_new_node(terrain_node)
        
Application().run()

i have sphere and “terrain”, but the terrain appear next to shere and i have cube :cry:
