Does aoMap function exclusively with THREE.BufferGeometry?

Can you provide guidance on setting up an aoMap for a standard THREE.Geometry object? Is there a demo available to reference?

 var uvCoordinates = geometry.attributes.uv.array; 

 geometry.addAttribute('uv2', new THREE.BufferAttribute(uvCoordinates, 2));

The code above is specifically designed for BufferGeometry.

Answer №1

To use an aoMap, you need to have a second set of UVs. If needed, you can easily create a duplicate of the first set.

For Geometry, follow these steps:

geometry.faceVertexUvs[ 1 ] = geometry.faceVertexUvs[ 0 ];

And for BufferGeometry, you can do this:

var uvs = geometry.attributes.uv.array;
geometry.addAttribute( 'uv2', new THREE.BufferAttribute( uvs, 2 ) );

... or simply:

geometry.attributes.uv2 = geometry.attributes.uv;
