[6] According to science author and Medium journalist Jan Krikke, axonometry, and the pictorial grammar that goes with it, has taken on a new significance with the introduction of visual computing and engineering drawing. It is also referred to as an orthographic projection. Another way to look at it is that in an orthographic projection, the projector lines intersect the plane being projected on at a perpendicular angle (thus, they are orthogonal, hence the projections name), whereas in an oblique projection, the projector lines form oblique angles (non-right angles) with the projection. the angle at which the object is viewed (the line of sight) in _____ projections, all three faces make different angles with the plane of projection. Side View: Prepare this view by gazing at the object from the right or left side. (In an orthographic projection, any point in the object is mapped onto the drawing by lowering a perpendicular from that point to the plane of the drawing.). In dimetric pictorials (for protocols see dimetric projection), the direction of viewing is such that two of the three axes of space appear equally foreshortened, of which the attendant scale and angles of presentation are determined according to the angle of viewing; the scale of the third direction (vertical) is . It depicts the objects length and breadth. Isometric projection The direction of seeing in isometric projection, the most prevalent kind of axonometric projection in engineering drawing, is such that the three axes of space seem equally foreshortened, with a common angle of 120 between them.

In all these cases, as with all axonometric and orthographic projections, such a camera would need a object-space telecentric lens, in order that projected lengths not change with distance from the camera. In isometric projection, all edges of the object along the direction of three isometric axes are foreshortened to 0.816 times their exact lengths. [7] However, video games utilizing isometric projectionespecially computer role-playing gameshave seen a resurgence in recent years within the indie gaming scene. However, in Multiview projection, these are referred to as primary views. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees. Cavalier: All lines perpendicular to the projection plane are projected with no change . In German literature, axonometry is based on Pohlke's theorem, such that the scope of axonometric projection could encompass every type of parallel projection, including not only orthographic projection (and multiview projection), but also oblique projection.
