How Do I Stop Zooming Effect On Objects When View Is Being Resized

Question

4.00/5 (1 vote)

See more:

On resizing of window/view, the objects tends to zoom in and out. I want the objects to be shown without this effect. So when i shrink the window the object should not shrink and vice versa. I have tried resetting the device with backbuffer (having new window size) but it is not helping. Am i missing anything that needs to be done?
It would be of great if any one can suggest any solution.

There's (at least) two things you can do.

The first is to adjust the camera position to compensate for the change in size of the screen. If the camera position relative the observed object is unchanged when the window size is doubled, the apparent size of the object will also double, but if you move the camera back you can compensate for this. This approach has the downside of actually changing the point of view, which may or may not be what you want.

Another approach is to render to a virtual surface and then render that surface unscaled to the screen. This requires the view port used for the camera to be independent of the size of the window and might look weird if the size of the virtual surface is smaller than the size of the window.
