I think it's worth mentioning that, if you have a texture of type `LUMINANCE`, when you read its content in shader, the `shader value` will be `the value you supplied`/255....
As we use 片段 rather than 片断 when talking about computer graphics in Chinese.
Maybe you should make a short article about point sprites- drawing GL_POINTS, setting gl_PointSize and interpolating your texture with gl_PointCoord

In this commit, I'm only editing the fundamentals page but I imagine this is the most-read page within the project, so I'm hoping it makes the biggest impact. By and...
I think this is a more accurate Chinese translation: 片段 / 片断 -> 片元
Describes why after applying perspective the F clips earlier when moving towards the screen. Not sure if I described well enough? Maybe the math should go in a new line...
in m3.js, the inverse function: const m00 = m[0 * 4 + 0]; const m01 = m[0 * 4 + 1]; const m02 = m[0 * 4 + 2]; const...
