[android-developers] GluProject not working… If the object haves Z=-1.0f and it is scaled to (0.01f,0.01f,0.0f) wich parameters i have to pass to GluProject?
until now, i worked with GluProject, perspective projection, and a
zoomable square centered on the screen with a lower left vertex
(-1,-1,0). I zoom the square adjusting the Z axis.
For example, i zoomed the square to Z=-5, and i call gluProject with
the openGL object parameters (-1,-1,0) to know the window pixels X,Y
position of that vertex of the square. It works fine.
But now, i changued my arquitecture, and now i'm not using Z to zoom,
i'm scaling to zoom. I have the square at Z=-1.0f, and initially it is
scaled to (0.01f,0.01f,0.0f), is a small square.
Wich X,Y,Z values i have to pass to gluProject? i'm passing -1,-1,0,
and gluProject is giving me erroneal x,y outPutCoords values,
(-101.774124,-226.27419)
