I want to know the location of the camera-oriented source code of the billboard, but I can’t find it after looking for a long time. Can anyone explain it to me?
Can you be more specific what you’re looking for in regards to the “camera-oriented” billboard code? For example the
eyeOffset and other properties related to the camera are handled in
Thank you for your reply。I will try my best to explain my problem。
As marked in the picture above, “attribute vec2 direction”, I don’t know where it came from. And where is the calculation method of this direction. “compressedAttribute0” I saw this, but I don’t see write direction from billboardCollection.js file. Looking forward to your reply
I’m honestly not sure. I believe all the buffer writes are being performed in
I do see the comment
// Instancing requires one non-instanced attribute. above where the direction attribute is added, but I also don’t see the write.
