Hi,
I downloaded and played with the opengl sample at
http://developer.android.com/training/graphics/opengl/draw.html
However, it uses the standard coordinate system for opengl, where 0,0
is at the center of the screen and -1,-1 at top-left and 1,1 at bottom-
right.
I want to use the screen's coordinate, where 0,0 is at top-left and
width,height is at bottom-right.
I already tried a dozen things, read about 30 articles, but since i'm
a newbie at opengl, i'm still stumped.
Can someone tell what it has to be done to change the coordinate so
that the given rectangle
static float squareCoords[] = { 10f, 10f, 0.0f, // top left
10f, 20f, 0.0f, // bottom left
20f, 20f, 0.0f, // bottom right
20f, 10f, 0.0f }; // top right
... is shown at screen?
thanks
guich
