Javascript 三点半不显示
我试图显示我的ply modifying three.js webgl_loader_ply示例,但它没有显示任何内容。当我用MeshLab打开帘布层时,我可以看到对象。我尝试过缩小、更改相机角度、禁用阴影灯,但都没有效果。还有什么建议吗 下面是已编辑的webgl_loader_ply.htmlJavascript 三点半不显示,javascript,three.js,Javascript,Three.js,我试图显示我的ply modifying three.js webgl_loader_ply示例,但它没有显示任何内容。当我用MeshLab打开帘布层时,我可以看到对象。我尝试过缩小、更改相机角度、禁用阴影灯,但都没有效果。还有什么建议吗 下面是已编辑的webgl_loader_ply.html <!DOCTYPE html> <html lang="en"> <head> <title>three.js webgl - P
