SView原生渲染入口脚本，在window.onload中调用，进行配置文件的读取，设置打开命令参数，调用打开命令进行文件打开

• 获取管理器并初始化配置路径

let configManager = sview0.getFrame().getConfigManager();
let commandsManager = sview0.getFrame().getCommandsManager();
initConfigPath();

• 读取配置文件

// 读取配置
configManager.load(sysConfigPath).then((ret) => {
   FunctionListener.configLoaded("system");
   let pmiServerUrl = M3D.Config.Parameters.getInstance().getStringParameter("pmiServerUrl");
   if (pmiServerUrl) {
       M3D.Shapes.ComText.option.pmiServer = pmiServerUrl;
   }
   configManager.load(docConfigPath).then((ret) => {
       FunctionListener.configLoaded("doc");
       //更新设置界面参数
       sview0.getViewer().getScene().getBackground().updateConfig();
       window.language = SView.UIManager.languageInfo = SView.FrameConfigure.getInstance().
                       getNumberParameter(M3D.Config.language) === 1 ? SView.UIManager.languageConstants.EN : SView.UIManager.languageConstants.CN;
       
       configManager.loadPropertiesConfigs(customPropertyPath,propertiesConfigPath).then((ret) => {
           //直接异步加载即可,后续如果有配置model名称的配置，则需要在加载完成后再执行打开逻辑
       });
       configManager.loadCommandConfigs(/*"File", "OpenSampleFile"*/).then((ret) => {
           FunctionListener.configLoaded("command");
       });
   });
});

• 获取打开命令

let openCommand = null;
if (ret) {
   openCommand = commandsManager.getCommand(SView.Commands.CommandNames.OPENSAMPLEFILE);
} else {
   //没有配置文件的情况
   let array = new Map();
   array.set("fullClassName", "SView.Commands.OpenCommand");
   openCommand = commandsManager.getCommand(SView.Commands.CommandNames.OPENSAMPLEFILE, array);
}

• 设置命令参数

if (svlxInfo.length === 1) {
   openCommand.fileInfo = svlxInfo[0];
} else {
   for (let fileInfo of svlxInfo) {
       if (fileInfo.directPara.get('downloadUrl')) {
           openCommand.addPath(fileInfo.directPara.get('downloadUrl'));
       }
   }
}

• 执行打开命令

commandsManager.execute(SView.Commands.CommandNames.OPENSAMPLEFILE);

• 直接进入模型比较时处理逻辑

    直接进入模型比较时不需要再单独执行打开命令，打开命令需要放在模型比较之后

//直接进入模型比较时调用
sview0.isCompare = true;
executeCommand("modelCompareButton");
//比较的模型地址
let path2 = basePath + "/models/Wankel Engine纹理材质贴图动画2（子件路径插值）.svlx";
filename2 = path2.slice(path2.lastIndexOf("/") + 1);
modelCompare(null, path2);
openState[0] = 0;
commandsManager.execute(SView.Commands.CommandNames.OPENSAMPLEFILE);
