The plane equation is known to be ax+by+cz+d=0，How to render this plane

Questions
1

I get a plane equation， ax + by + cz + d = 0，a，b，c，d is known，How can I render this plane?

2

What have you tried so far?

I now know how to add a plane, but if the plane equation is tilted, I don’t know what to do.

ax + by + cz = d is the so called scalar notation. In order to use THREE.Plane, you need the following:

p · n = d which is called the vector notation. In this form, n = [a, b, c].

If you know n and d, it should be possible to create an instance of THREE.Plane and then use THREE.PlaneHelper in order to visualize it.

thank you very much

thanks, i see

If I want to create a plane through PlaneBufferGeometry and MeshBasicMaterial, what should I do.because I want to use Raycaster to get the focus with the plane to complete my needs

If I got you correctly, then you can use .ray property of THREE.Raycaster() and its .intersectPlane() method.
