Cesium相机进入地下问题，修改ScreenSpaceCameraController源码

想赚波分，所以拿出来分享了，真实有效，不坑人。替换scene下的ScreenSpaceCameraController代码，用cesium.js自己打开文件，找到这部分替换，另外上传不能修改，其中pickGlobe函数用下面替换 function pickGlobe(controller, mousePosition, result) { var scene = controller._scene; var globe = controller._globe; var camera = scene.camera; if (!defined(globe)) { return undefined; } var depthIntersection; if (scene.pickPositionSupported) { depthIntersection = scene.pickPositionWorldCoordinates(mousePosition, scratchDepthIntersec tion); } var ray = camera.getPickRay(mousePosition, pickGlobeScratchRay); var rayIntersection = globe.pick(ray, scene, scratchRayIntersection); var pickDistance = defined(depthIntersection) ? Cartesian3.distance(depthIntersection, camera.positionWC) : Number.POSITIVE_INFINITY; var rayDistance = defined(rayIntersection) ? Cartesian3.distance(rayIntersection, camera.positionWC) : Number.POSITIVE_INFINITY; if (pickDistance < rayDistance) { return Cartesian3.clone(depthIntersection, result); } return Cartesian3.clone(rayIntersection, result); }
