re: WebGL point sprites, a tutorial VIEW POST


This was a great great tutorial. Thank you :)
I would like to understand why you create a buffer of 500 floats ?
Where is this buffer used in the program ?
And... please write some other WebGL tutorials.
(Sorry for my english.)


So the buffer is new Float32Array(1000);, it actually takes 1000 floats.

But since it's used to provide a vec2, an x,y vector, then it supports 500 sprites.

The "500" is just a random number. The demo will fail if you try to add more than 500 images. If you wanted to support any number of sprites, you'd have to create a new, larger array when the original ran out of space.

Also, thanks, I'm glad you enjoyed the article!


Understood. Thank you this explanation.
