批量处理网格(BatchedMesh)
核心
Mesh 的特殊版本，支持多绘制批量渲染。如果您必须渲染大量具有相同材质但具有不同世界变换和几何形状的对象，请使用 BatchedMesh。使用 BatchedMesh 将帮助您减少绘制调用的数量，从而提高应用程序的整体渲染性能。
示例
javascript
const box = new THREE.BoxGeometry( 1, 1, 1 );
const sphere = new THREE.BoxGeometry( 1, 1, 1 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
// initialize and add geometries into the batched mesh
const batchedMesh = new BatchedMesh( 10, 5000, 10000, material );
const boxId = batchedMesh.addGeometry( box );
const sphereId = batchedMesh.addGeometry( sphere );
// position the geometries
batchedMesh.setMatrixAt( boxId, boxMatrix );
batchedMesh.setMatrixAt( sphereId, sphereMatrix );
scene.add( batchedMesh );const box = new THREE.BoxGeometry( 1, 1, 1 );
const sphere = new THREE.BoxGeometry( 1, 1, 1 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
// initialize and add geometries into the batched mesh
const batchedMesh = new BatchedMesh( 10, 5000, 10000, material );
const boxId = batchedMesh.addGeometry( box );
const sphereId = batchedMesh.addGeometry( sphere );
// position the geometries
batchedMesh.setMatrixAt( boxId, boxMatrix );
batchedMesh.setMatrixAt( sphereId, sphereMatrix );
scene.add( batchedMesh );
