I’m struggling to get the current matrix in order to invert its y-coordinates. I need to have my origin [0, 0] at the [Top, Left] of the iPad screen! Can anyone give a quick hint?
any ideas? maybe @Simeon?
Write a function
f(y)= HEIGHT - y end
and use f(y) in your code in place of y?
want to do that on matrix base, because i can popMatrix() and later pushMatrix()! this seems to me more flexible when i decide to mix up inverted view and normal codeas behaviour…
i have this already:
modelMatrix():scale(1, -1)
but how to make the changes see?
Why don’t you:
translate(0, HEIGHT)
scale(1, -1)
This should invert the screen
BEST! This solves it! Thank you very much
