Measure light intensity

The thing is that I could only make it work on a friend’s computer where I could print values on the array (i.e. [ 123, 123, 123, 255 ]). In the rest of computers I couldn’t print more values, it always says [ 0, 0, 0, 255 ]

Javier that’s not going to tell me anything. OS/Browser name version?

Here is a demo that uses WebGL readPixels() to get pixel data under mouse:
Z_Model.html (101.4 KB)

To activate keyboard commands make the mouse is over the canvas and has focus.

• Press C key on keyboard to launch readPixels().
• Press E key Chrome 95+ to launch EyeDropper().
