  2. Scheimpflug principle - Wikipedia

    en.wikipedia.org/wiki/Scheimpflug_principle

    Thus at the hyperfocal distance, the DoF on a plane parallel to the image plane extends a distance of J on either side of the PoF. With some subjects, such as landscapes, the wedge-shaped DoF is a good fit to the scene, and satisfactory sharpness can often be achieved with a smaller lens f -number (larger aperture ) than would be required if ...

  3. Ceiling (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Ceiling_(aeronautics)

    The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it is the density altitude at which flying in a clean configuration , at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power, will produce a given rate of climb.

  4. SolidWorks - Wikipedia

    en.wikipedia.org/wiki/SolidWorks

    SolidWorks (stylized as SOLIDWORKS) is a brand within Dassault Systèmes that develops and markets software for solid modeling computer-aided design (CAD), computer-aided engineering (CAE), 3D CAD design, collaboration, analysis, and product data management. [2] The company introduced one of the first 3D CAD applications designed to run on a ...

  5. Parallel curve - Wikipedia

    en.wikipedia.org/wiki/Parallel_curve

    Distance parameter may be negative, too. In this case one gets a parallel surface on the opposite side of the surface (see similar diagram on the parallel curves of a circle). One easily checks: a parallel surface of a plane is a parallel plane in the common sense and the parallel surface of a sphere is a concentric sphere.

  6. Image plane - Wikipedia

    en.wikipedia.org/wiki/Image_plane

    If one makes the analogy of taking a photograph to rendering a 3D image, the surface of the film is the image plane. In this case, the viewing transformation is a projection that maps the world onto the image plane. A rectangular region of this plane, called the viewing window or viewport, maps to the monitor.

  7. Parallel projection - Wikipedia

    en.wikipedia.org/wiki/Parallel_projection

    In three-dimensional geometry, a parallel projection (or axonometric projection) is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other. It is a basic tool in descriptive geometry.

  8. Parallax mapping - Wikipedia

    en.wikipedia.org/wiki/Parallax_mapping

    This effect is commonly used for rendering windows in order to fake 3D interiors for example. Parallax mapping, as described by Kaneko et al., is a single step process that does not account for occlusion. Subsequent enhancements have been made to the algorithm incorporating iterative approaches to allow for occlusion and accurate silhouette ...

  9. Image rectification - Wikipedia

    en.wikipedia.org/wiki/Image_rectification

    If the images to be rectified are taken from camera pairs without geometric distortion, this calculation can easily be made with a linear transformation.X & Y rotation puts the images on the same plane, scaling makes the image frames be the same size and Z rotation & skew adjustments make the image pixel rows directly line up [citation needed].
