+iphone支持 EXT_DEPTH 的 orthoCamera下， paraboloid_point_shape形状的 点云绘制不出。导致无法pick出点云位置
 
+因为不支持的曾经加过这个：
+if(!Features.EXT_DEPTH.isSupported() && this.shape === PointShape.PARABOLOID){
+    this.shape = PointShape.SQUARE ;//强行替换
+}
 
 
+结果：在#if defined paraboloid_point_shape处添加一行：
+gl_FragDepthEXT = clamp(gl_FragDepthEXT, 0.0, 1.0);
+这句在解决ios16全景里经常有黑块是一样的处理方式。

+--------------------------------------------------------------
+另外将depthBasicMaterial和线的resolution改为了resolution2否则手机的遮挡错误。但是为何之前没事？且专门记录了应该使用resolution
