  2. Glide reflection - Wikipedia

    en.wikipedia.org/wiki/Glide_reflection

    When the glide plane is perpendicular to the screen, these planes can be represented either by dashed lines when the glide is parallel to the plane of the screen or dotted lines when the glide is perpendicular to the plane of the screen. Additionally, a centered lattice can cause a glide plane to exist in two directions at the same time.

  3. Stereographic projection - Wikipedia

    en.wikipedia.org/wiki/Stereographic_projection

    The plane z = 0 runs through the center of the sphere; the "equator" is the intersection of the sphere with this plane. For any point P on M , there is a unique line through N and P , and this line intersects the plane z = 0 in exactly one point P ′ , known as the stereographic projection of P onto the plane.

    en.wikipedia.org/wiki/Constraint_(computer-aided...

    The shaft and pulleys share a common centerline. The constraints of the key are set in relation to the keyseat. A constraint in computer-aided design (CAD) software is a limitation or restriction imposed by a designer or an engineer upon geometric properties [1]: 203 of an entity of a design model (i.e. sketch) that maintains its structure as the model is manipulated.

  5. OpenVSP - Wikipedia

    en.wikipedia.org/wiki/OpenVSP

    A workspace window and a "Geometry Browser" window open. The workspace is where the model is displayed while the Geometry Browser lists individual components in the workspace, such as fuselage and wings. These components can be selected, added or deleted, somewhat like a feature tree in CAD software such as Solidworks. When a component is ...

  6. Plücker coordinates - Wikipedia

    Then their respective planes are perpendicular to vectors a and b, and the direction of L must be perpendicular to both. Hence we may set d = a × b, which is nonzero because a, b are neither zero nor parallel (the planes being distinct and intersecting). If point x satisfies both plane equations, then it also satisfies the linear combination

  9. Rendering (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Rendering_(computer_graphics)

    The vector displays of the 1960s-1970s used deflection of an electron beam to draw line segments directly on the screen. Nowadays, vector graphics are rendered by rasterization algorithms that also support filled shapes. In principle, any 2D vector graphics renderer can be used to render 3D objects by first projecting them onto a 2D image plane.
