How can I solve z-fighting using Three.js

Question

I'm learing three.js and I faced a z-fighting problem.

There are two plane object, one is blue and the other is pink. And I set the positions using the flowing codes:

plane1.position.set(0,0,0.0001);
plane2.position.set(0,0,0);

Is there any solution in three.js to fix all the z-fighting problem in a big scene?

I ask this problem because I'm working on render a BIM(Building Information Model, which is .ifc format) on the web. And the model itself have so much faces which are so closed to each other. And it cause so much z-fighting problems as you can see:

Is three.js provide this kind of method to solve this problem so that I can handle this z-fighting problem just using a couple of code?

Answer 1

Three.js has given a general solution like this: var renderer = new THREE.WebGLRenderer({ logarithmicDepthBuffer: true }); The demo is provided also here: https://threejs.org/examples/webgl_camera_logarithmicdepthbuffer.html It changes the precision of depth buffer, Which generally could resolve the z-fighting problem in a distance.
