Enhance the illumination within the three.js environment

Currently, I am working on rendering solid models in three.js, inspired by the way GitHub showcases STL files like the Octocat head. However, I am facing difficulties in setting up the lighting to achieve an optimal look. The current rendering has its limitations, as shown below:

One of the main issues is that the model looks good only from certain angles, resulting in poor contrast and planes appearing to be the same shade of grey when viewed from different perspectives.

The snippet of code I am using for lighting is:

light = new THREE.DirectionalLight(0xffffff, 1);
light.position.copy(camera.position);
scene.add(light);

Furthermore, the light follows the camera when it moves.

Do you have any suggestions on how to enhance the overall lighting and appearance of the model?

Answer №1

If you want to enhance the lighting on your rendered object, here are a few suggestions:

Experiment with different material types:

Each material reflects light uniquely. Instead of using a Basic material, consider using a Lambert material. You can define the material when creating your mesh. For example, define your material first:

var material4 = new THREE.MeshLambertMaterial({color: 0xffffff, vertexColors: THREE.FaceColors});

Then, apply the material to your object:

var objectMesh = new THREE.Mesh(objectGeom, material4);

For more information on the Lambert Material, refer to the documentation here.

Include additional light sources:

Most objects benefit from multiple light sources coming from different angles. You can add new lights using the following code:

lights[ 0 ] = new THREE.PointLight( 0xffffff, 1, 0 );
lights[ 0 ].position.set( 0, 200, 0 );
scene.add( lights[ 0 ] );

Note that lights[] is an array where you can add multiple lights.

Use directional light helpers:

During development, it can be helpful to use directional light helpers to visualize the light sources. For example:

directionalLightHelper[0] = new THREE.PointLightHelper(lights[0], 1);
scene.add( directionalLightHelper[0] );

Personally, I gravitate towards utilizing the Standard material.

standardMaterial = new THREE.MeshStandardMaterial( {
                    color: 0xffffff,
                    metalness: 0.5,
                    roughness: 0.5,
                } );

I also recommend activating gammaOutput for the renderer, as it significantly enhances the appearance of overbright areas:

        renderer.gammaInput = true;
        renderer.gammaOutput = true;

From a creative perspective, it is ideal for the light to emanate from the top left corner of the screen, slightly offset. Additionally, enabling shadows ensures that the object consistently casts a shadow towards the bottom right.
