问题
When entering the geometry, for example a sphere mesh, it acts as if the geometry doesn't exist. The color and texture are visible on the outside. But once I zoom into the mesh, the properties are gone.
How can I make the color and texture of a sphere mesh be visible inside the mesh?
回答1:
mesh.material.side = THREE.DoubleSide;
Or
mesh.material.side = THREE.BackSide;
three.js r.62
