Lighting uniformity concept in Three.js

My 3D model needs to be uniformly lit from all angles without any shadows. Currently, I am using a Spotlight, but its directional nature only lights up certain parts of the model at a time.

One solution I am considering is to place a spotlight at each corner of the bounding box, pointing towards the center. This would mean having 8 spotlights in total.

I'm not sure if this is the standard way to address this issue, and I'm concerned about potential limitations. Can you recommend a better approach?

Answer №1

There are multiple methods to achieve consistent lighting in three.js.

If you desire a spotlight or directional light, remember to incorporate some ambient light:

scene.add( new THREE.AmbientLight( 0x222222 ) );

Additionally, make sure to set material.ambient to match material.color to ensure the unilluminated areas of your model appear correctly. (Note that material.ambient is being deprecated in r.71).

Another option is to utilize a hemisphere light.

Alternatively, if shadows are not a concern, you can attach a point light to the camera:

scene.add( camera ); // necessary if the camera has child elements

camera.add( new THREE.PointLight( 0xffffff, 1 ) );

By doing so, the scene will be evenly illuminated, regardless of the viewing angle.
