"WebStencil formats can only be used for Textures if OpenGL 4.4 or ARB_texture_stencil8 is available. Reading from a stencil-only texture is treated as reading from a one-component unsigned integer texture. So you must use usampler* types when accessing them, just as for accessing the stencil component of depth/stencil textures. Required formats " - Opengl texture

WebOpenGL ES 1.1 added features such as mandatory support for multitexture, better multitexture support (including combiners and dot product texture operations), automatic mipmap generation, vertex buffer objects, state queries, user clip planes, and greater control over point rendering. WebOpenGL requires that textures all have a 4-byte alignment e.g. their size is always a multiple of 4 bytes. Normally this won't be a problem since most textures have a width …

Texture coordinates do not depend on resolution but can be any floating point value, thus OpenGL has to figure out which texture pixel (also known as a texel) to map the texture coordinate to. This becomes especially important if you have a very large object and a low resolution texture. Web关于旋转方向，因为opengl在屏幕空间使用右手系，而且摄像机z轴正方向指向屏幕外，所以根据右手法则，箱子逆时针旋转最后我们试试缩放我们还可以试试移动后缩放（注意，必须移动后缩放，不然移动会不准确）
