  2. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.

    Picture plane; Plans (drawings) Projection (linear algebra) ... The isometric transform from a point a x,y,z in 3D space to a point b x,y in 2D space looking into the ...

  4. Planar projection - Wikipedia

    en.wikipedia.org/wiki/Planar_projection

    Planar projections are the subset of 3D graphical projections constructed by linearly mapping points in three-dimensional space to points on a two-dimensional projection plane. The projected point on the plane is chosen such that it is collinear with the corresponding three-dimensional point and the centre of projection .

  5. Multiview orthographic projection - Wikipedia

    en.wikipedia.org/wiki/Multiview_orthographic...

    These six planes of projection intersect each other, forming a box around the object, the most uniform construction of which is a cube; traditionally, these six views are presented together by first projecting the 3D object onto the 2D faces of a cube, and then "unfolding" the faces of the cube such that all of them are contained within the ...

  6. Perspective (graphical) - Wikipedia

    en.wikipedia.org/wiki/Perspective_(graphical)

    Linear or point-projection perspective works by putting an imaginary flat plane that is close to an object under observation and directly facing an observer's eyes (i.e., the observer is on a normal, or perpendicular line to the plane). Then draw straight lines from every point in the object to the observer. The area on the plane where those ...

  7. Orthographic projection - Wikipedia

    en.wikipedia.org/wiki/Orthographic_projection

    Orthographic projection (also orthogonal projection and analemma) [a] is a means of representing three-dimensional objects in two dimensions.Orthographic projection is a form of parallel projection in which all the projection lines are orthogonal to the projection plane, [2] resulting in every plane of the scene appearing in affine transformation on the viewing surface.

  8. Parallel projection - Wikipedia

    en.wikipedia.org/wiki/Parallel_projection

    In an oblique projection (at right), the projection lines are at a skew angle to the image plane. Every parallel projection has the following properties: It is uniquely defined by its projection plane Π and the direction of the (parallel) projection lines. The direction must not be parallel to the projection plane. Any point of the space has a ...

  9. Descriptive geometry - Wikipedia

    en.wikipedia.org/wiki/Descriptive_geometry

    Given the X, Y and Z coordinates of P, R, S and U, projections 1 and 2 are drawn to scale on the X-Y and X-Z planes, respectively. To get a true view (length in the projection is equal to length in 3D space) of one of the lines: SU in this example, projection 3 is drawn with hinge line H 2,3 parallel to S 2 U 2.
