After loading a model with THREE.OBJMTLLoader, I want to add a vertex and fragment shader to it.
var loader = new THREE.OBJMTLLoader();
loader.addEventListener('load', function(event) {
var mesh = event.content;
scene.add(mesh);
});
loader.load('model/machine.obj', 'model/machine.mtl');
What is the process for applying a vertex and fragment shader to the loaded model?
Building on Gero3's response, implementing the suggested code will ensure that all meshes within the content have the correct material applied:
let customMaterial = new THREE.ShaderMaterial({
uniforms: myShader.uniforms,
fragmentShader: myShader.fragmentShader,
vertexShader: myShader.vertexShader
});
let selectedObject = event.content;
selectedObject.traverse(function(child) {
if (child instanceof THREE.Mesh) {
child.material = customMaterial;
}
});
scene.add(selectedObject);
To incorporate both a vertex and fragment shader, you must utilize a shadermaterial.
var material = new THREE.ShaderMaterial( {
fragmentShader: shader.fragmentShader,
vertexShader: shader.vertexShader,
uniforms: shader.uniforms
} ),
