Hi,
Thank you for the answer. I have studied several times the doc for
Unfortunately clutter_stage_set_perspective() and cogl_perspective().
May be I wasn't able to understand it or it is just not enough
descriptive . But I spent some time with experimenting it. I think these
functions are not appropriate for the trick I need.
Let's see it a bit more close:
------------
void clutter_stage_set_perspective (ClutterStage *stage, gfloat fovy,
gfloat aspect, gfloat z_near, gfloat z_far);
Sets the stage perspective.
stage :
A ClutterStage
fovy :
the field of view angle, in degrees, in the y direction
aspect :
the aspect ratio that determines the field of view in the x direction.
The aspect ratio is the ratio of x (width) to y (height)
z_near :
the distance from the viewer to the near clipping plane (always
positive)
z_far :
the distance from the viewer to the far clipping plane (always positive)
------------
z_near, z_far and aspect is good as it is for me. fovy effectively
scales the viewport. This is not what I need.
cogl_perspective has the same parameter and thus it is also not what I
would need.
Thank you anyway,
Peter
