var hit = scene.pick({ pickSurface: true, canvasPos: [23, 131] });

if (hit) { // Picked an Entity

 var entity = hit.entity;

 var primitive = hit.primitive; // Type of primitive that was picked, usually "triangles"
 var primIndex = hit.primIndex; // Position of triangle's first index in the picked Entity's Geometry's indices array
 var indices = hit.indices; // UInt32Array containing the triangle's vertex indices
 var localPos = hit.localPos; // Float32Array containing the picked Local-space position on the triangle
 var worldPos = hit.worldPos; // Float32Array containing the picked World-space position on the triangle
 var viewPos = hit.viewPos; // Float32Array containing the picked View-space position on the triangle
 var bary = hit.bary; // Float32Array containing the picked barycentric position within the triangle
 var normal = hit.normal; // Float32Array containing the interpolated normal vector at the picked position on the triangle
 var uv = hit.uv; // Float32Array containing the interpolated UV coordinates at the picked position on the triangle
