Upon loading the Wavefront obj file from this link, I noticed that the normals were not calculated correctly, resulting in incorrect shading of the model. The code used to load the *.obj model was based on a modified version of the original project's loader / obj example. In such cases, after applying transformations like scaling to the model, it is usually necessary to call functions like dirtyDisplayList, UpdateModel, or RecalculateNormals to sync the model with the changes made. In Three.js, common functions for this purpose are geometry.computeFaceNormals() and
geometry.computeVertexNormals( true )However, when I tried calling geometry.computeFaceNormals() and
geometry.computeVertexNormals( true )I am unsure what mistake I am making here. Any insights on this issue would be greatly appreciated.
var I_prof = new THREE.OBJLoader();
I_prof.load('obj/male02/new_I_Profile.obj', function(geometry){
geometry.scale.set(10, 10, 10);
geometry.rotation.x = 3.1415/2;
geometry.position.z = -0;
geometry.position.x = 0;
geometry.position.y =0;
//geometry.computeFaceNormals();
//geometry.computeVertexNormals( true );
scene.add(geometry);
} );
