I would like to use projected map for displaying satellite images(tif) just like
commercially available or opensource 2D image displaying software/utilities.
Some testing also done with osgearth. It's fine to me. But want to know is there any difference
in terms of quality? I know well that osgearth is meant for high performance 3D visualization and I have been using as well. But kindly clarify me to use it for 2D applications.
On the projected map, I display only a small scene and tried to disable the visibility of background map.
Though, I get white background layer. SetNodeMask(0) to mapnode disables completely including my scene. How to disable the visibility of background(base layer)?
I built osgearth-2.10.1 on osg-3.4.2 and included GLCORE while building to support GL3.
At the end of build, with osgearth_version --caps, it shows "core profile = off".
On running earth file, the command prompt shows
"Non-GL3 compatibility version...".
I am not sure why GL3 was not included.???
And, my rendering has slowed as well. Had GL3 absence effect on performance?
Another observation is that while zooming in osgearth I get smoothed display.
I would like to have pixel wise discrimination in the way other display utilities doing
(depicted in the attachment). How can it be done?
created 2D-image display with fake profile with "eqc-wgs84". bounds was set to image scans and pixels.
The display is fine. But I get pixel length more than one at highest zoom-in level.
roughly 3.5 and above length. (i.e. width > 2 and height > 2). more than 2 image pixels into one display grid. The same depicted in the picture,
even tried with min_tile_range_factor=12 thru 30.
End of image in along and across provided readout equivalent to scans and pixels of the image.
how to get one display grid pixel to one pixel in image file?
