Fov projection
WebJan 6, 2024 · The projection transformation converts vertices into the coordinate system used for the viewport. A viewport is also used to specify the range of depth values on a render-target surface into which a scene will be rendered (usually 0.0 to 1.0). ... The viewing frustum is defined by fov (field of view) and by the distances of the front and back ... Webhorizontal field of view = 2 atan (0.5 width / focallength) where "width" is the horizontal width of the sensor (projection plane). So for example, for a 35mm film (frame is 24mm x 36mm), and a 20mm (focal length) lens, the horizontal FOV would be almost 84 degrees (vertical FOV of 62 degrees). The above formula can similarly be used to ...
