About showing grid lines

[ninewill]

Hello ~
I have any questions, how to make a square object display grid lines？

[Mugen87]

You can achieve this with THREE.WireframeGeometry.

Thank u, but I still can’t work after execution.

[Mugen87]

mesh = new THREE.Mesh(geometry, material, line);

This statement is not correct since the constructor of THREE.Mesh only takes two parameters.
Try it like so:

mesh = new THREE.Mesh(geometry, material);
mesh.add( line );

Thank you for your suggestion. The frame line was successfully displayed, but the main body color disappeared. I originally wanted the main color and white line frame.

Example:

Pleas use the exact code I have provided you. You should do:

mesh.add( line );
scene.add( mesh );

Right now, you are not adding the mesh to your scene.
