Descriptive geometry uses the image-creating technique of imaginary, parallel projectors emanating from an imaginary object and intersecting an imaginary plane of projection at right angles.

:" [ Primary geometry is ] the arrangement in space of lines of projection from a 3-D object to a plane of projection, and secondary geometry, the relationships between the points, lines and shapes of the drawn projection on a 2-D surface ."
3.
As opposed to direct volume rendering, which requires every sample value to be mapped to opacity and a color, " maximum intensity projection " picks out and projects only the voxels with maximum intensity that fall in the way of parallel rays traced from the viewpoint to the plane of projection.
4.
The centre of projection can be thought of as the location of the observer while the plane of projection is the surface on which the two dimensional projected image of the scene is recorded or from which it is viewed ( e . g ., photographic negative, photographic print, computer monitor ).
5.
An object is " considered to be in an inclined position resulting in foreshortening of all three axes ", and the image is a " representation on a single plane ( as a drawing surface ) of a three-dimensional object placed at an angle to the plane of projection . " Lines perpendicular to the plane become points, lines parallel to the plane have true length, and lines inclined to the plane are foreshortened.
6.
These 6 planes of projection intersect each other, forming a box around the object, the most uniform construction of which is a cube; traditionally, these 6 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 same plane ( namely, the plane of the medium on which all of the images will be presented together, such as a piece of paper, or a computer monitor, etc . ).
