Hello,
@Robert, Mahendra is ok :).
Btw, i gave GL_FLOAT as the type, i took Robert's suggestion and itseems
working, however, i'm getting values from 0-255 (converted?) and not the
actual float values stored.
this is what i'm exactly doing :
code:
(float&)image->data(0,0,0)[0] = 0.33
[1] = 0.56
[2] = .83
and printing them back casting to float. what am i doing wrong?
Thanks,
Best regards.
