快速运行 - 我正在尝试构建一个包含 360 度图像的画廊，当点击一个画廊图像时，模态打开并在内部显示 360 度查看器，但我希望图像根据被点击的画廊图像动态变化.
THREE.WebGLRenderer: image is not power of two (1920x960). Resized to 2048x1024
blob:http://nolan.bfdevserver.com/7ca91892-2e3b-4fff-b672-ec250ef13498 new image blob
blob:http://nolan.bfdevserver.com/7788013c-9611-497a-bc12-66a06bb2244f old image blob
THREE.WebGLRenderer: image is not power of two (0x0). Resized to 0x0
THREE.WebGLRenderer: Texture is not power of two. Texture.minFilter should be set to THREE.NearestFilter or THREE.LinearFilter.
THREE.Texture
WebGL: INVALID_VALUE: texImage2D: no canvas
这是我在控制台中收到的错误。正如您在下面的代码中看到的:
material.minFilter = THREE.LinearFilter;
所以我不确定为什么会这样。

我已经关注这个几个小时了，所以任何帮助甚至只是类(class)指导都将不胜感激。提前致谢!
最佳答案
要修正二次方错误，需要修改这一行:
material.minFilter = THREE.LinearFilter;
到
material.map.minFilter = THREE.LinearFilter;
为了更新纹理，回到标准图像 url 与 blob url 并使用:
if(newestImage) {
material.map = new THREE.TextureLoader().load(newestImage);
}
关于javascript - Three.JS 错误 - 纹理不是二的幂/无法更改纹理，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56941798/
