A viewing system of a vehicle, comprising: - a plurality of image capture units (110, 120, 130, 140) for recording an image of an environment of the vehicle in the form of image data; - a display device for displaying an output image; and - an arithmetic unit which is connected to the plurality of image capture units (110, 120, 130, 140) and to the display device, wherein the arithmetic unit is configured to - determine a virtual, three-dimensional space and a surface, the surface at least partially delimitting the virtual, three-dimensional space; - calculate a projection of the image data directly onto the surface; - calculate a virtual vehicle object as a computer-generated graphic from predetermined data (Obj) in the virtual, three-dimensional space; and - generate the output image by rendering a viewing volume (711, 721) which includes the virtual vehicle object, the viewing volume (711, 721) being delimited by the surface, the viewing volume (711, 721) being based on a viewing position (710, 720) and a viewing angle (712, 722) and a zoom factor in the virtual, three-dimensional space, wherein, to control the viewing volume (711, 721), the arithmetic unit is configured to - change the viewing position (710, 721) between a first coordinate in the virtual, three-dimensional space and a second coordinate in the virtual, three-dimensional space; and/or - change the viewing angle (712, 722) between a first direction in the virtual, three-dimensional space and a second direction in the virtual, three-dimensional space; and/or - change the zoom factor (714, 724) between a first zoom value and a second zoom value, wherein the arithmetic unit is configured to - determine a collision probability of a collision between a region of the vehicle and an object in the environment based on at least one ascertained distance (d 1) to the object in the environment of the vehicle, and wherein at least one predetermined viewing volume (711, 712) is associated with each region (101, 102, 103, 104, 105, 106) of the vehicle, the predetermined viewing volume (711, 712) having a part (501, 502, 503, 504, 505, 506) of the vehicle object associated with the region (101, 102, 103, 104, 105, 106) and a surface region of the surface adjacent to the associated part (501, 502, 503, 504, 505, 506), and characterized in that the arithmetic unit is configured to - control the predetermined viewing volume (711, 712) associated with the region (101, 102, 103, 104, 105, 106) based on an exceeding of a threshold by the collision probability in order to render the part (501, 502, 503, 504, 505, 506) of the vehicle object associated with the region (101, 102, 103, 104, 105, 106) and the surface region of the surface adjacent to the associated part (501, 502, 503, 504, 505, 506). - a plurality of image capture units (110, 120, 130, 140) for recording an image of an environment of the vehicle in the form of image data;
