Is it possible to flatten a 3D scene into a 2D image?

    Hi,

    I created a 3D scene in unity3D where camera viewing direction coincides with my eye viewing screen direction, and two objects along the viewing direction at different distances. I would like to flatten the viewing scene and export it as a 2D image. Is it possible?

    Thanks
    P.S. I am using 2019.2.1f1 release on ubuntu18.04.

    You mean "render"?
    Or setting camera to be orthographic?

    Here is our in game map camera, its a isometric camera pointing down on the world

    Code (CSharp):
    1.  
    2. var rect = RealtimeMapImage.GetComponent<RectTransform>();
    3. mapCamera.aspect = rect.rect.width / rect.rect.height;
    4.  
    5. mapCamera.targetTexture = new RenderTexture(mapCamera.pixelWidth, mapCamera.pixelHeight, 24);
    6.  
    7. mapCamera.Render();
    8. RealtimeMapImage.texture = mapCamera.targetTexture;
    9.  
    Looks like this in game

    The 3D scene is orthographic. I would like to convert it to a 2D perspective image.
    Thank you

    Thank you for sharing the code segment. I will look into it.

    ...what?

    Give us an example of what you're trying to do, because you're really not making a lot of sense here.

    To me it sounds like you want to create impostor equivalent. Or relevant. Or simple 2d image of 3d scene, which can be output on ingame tv/screen. Either way, look at Andrew example and try it. Use different angles of the camera.

    The set of all possible 3D scenes for a movie is really smaller than the set of all 3D scenes dqfansurvey.

    If it's a background image then you could render it to a skybox. I think reflection probes do this automatically not sure how to convert their texture into a skybox.
