Question

我是webGL的新手，我试图在firefox中使用three.js显示一个json模型。我只是得到一个空白的屏幕。显示的错误是＆＃34; NS_ERROR_DOM_BAD_URI：访问受限制的URI被拒绝＆＃34;在three.js。请告诉我们要包含哪些其他js sripts和修改。代码附后。模型是3d乙烷分子。我们希望它只是在屏幕上旋转。

    function animate() {

        render();
    }

    function render() {
        renderer.render(scene, camera);
    }

NS_ERROR_DOM_BAD_URI错误通常是因为出于安全原因无法访问给定文件。

据我所知，如果model.js与你的html文件在同一个文件夹中，它应该与firefox脱机工作。对于其他浏览器，只有代码在Web服务器上运行时才有效，而不是在本地计算机上运行。

使用three.js加载json模型
