Electronic device and method for providing 3d image including graphic object

An electronic device comprising:

• a display;
• a memory;
• and
• at least one processor, comprising processing circuitry, operably connected to the display and the memory,
• wherein the memory stores instructions that are executable by the at least one processor individually and/or collectively, and when executed, cause the electronic device to:
• render a 2D image and/or a 3D image that includes a first image recognizable to a user's left eye and a second image including a right-eye image recognizable to a user's right eye, and output the same via the display;
• determine, in a case that the 3D image to be output via the display includes a first graphical object and a second graphical object placed to overlap at least partially with the first graphical object, z-axis direction positions indicating positions in a z-axis direction perpendicular to the display at which the first graphical object and the second graphical object are to be placed on the 3D image based on attributes of the first graphical object and the second graphical object;
• and
• render the 3D image, including the first graphical object and the second graphical object, wherein the first graphical object and the second graphical object are recognizable respectively at the determined z-axis direction positions.
