Following my previous topic an additional question remains : how can I create a buffer with the fragment normal? (using or not GeometryBufferRenderer)(please).
I would like to keep the normal shading on the mesh but I need the data like when I use the flat shading.
All my different attempts result in a black screen.
I think it shows me the normal of like a plan in front of the camera because when I display the positions, I have the screen split into 4 with each quarter of the screen of a color (green, yellow, black, red in order) .
Thanks in advance!
