	GameDev.net - Axonometric Projections - A Technical Overview
		In the projection, the y-axis usually remains the vertical axis, the z-axis is skewed and the x-axis may either be horizontal, as in the figure at the right, or be skewed as well.
		NEN 2536 describes an isometric projection that is symmetric with regards to the vertical axis; the angle between the x- and y-axes, and between the z- and y-axes, is 60 degrees.
		In the military projection, the angles of the x- and z-axes are at 45°, meaning that the angle between the x-axis and the z-axis is 90°.

	Reference.com/Encyclopedia/Graphical projection
		Orthographic projection is derived from the principles of descriptive geometry and may produce an image of a specified, imaginary object as viewed from any direction of space.
		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 determined separately.
		Perspective projection is usually categorized into one-point, two-point and three-point perspective, depending on the orientation of the projection plane towards the axes of the depicted object.

		Therefore, parallel projections are useful in applications requiring the relative proportions of an object to be maintained.
		To project the top view of the 3-D object, the y-coordinates are discarded and the x- and z-coordinates for each point are mapped to the viewplane.
		Trimetric projections have a potential disadvantage in that measurement of lines along the axes is difficult because of a difference in scaling factors.

	TRACEY - representation - Riley
		Dimetric projection is a special case of axonometric in which scales along two axes are equal, the third axis being different.
		Planometric oblique projection is a special case of oblique projection, often inaccurately called 'axonometric', where the plan face of the object is parallel to the plane of projection (and usually rotated through 45º) and projectors are inclined obliquely to the plane of projection.
		This family of projection conventions as defined by BS 1192 differs from orthographic and oblique projections because the projected lines from the object to the plane of projection are not parallel, but converge to a point, generally regarded as the position of an observer's eye.

	[No title]
		In both multiview projection, and axonometric projection, the observer is considered to be at infinity, and the visual rays are perpendicular to the plane of projection.
		Since the principal edges and surfaces of the object are inclined to the plane of projection, the lengths of the lines, the sizes of the angles, and the general proportions of the object vary with the infinite number of possible positions in which the object may be placed with respect to the plane of projection.
		Axonometric projections are classified as (a) isometric projection, (h) dimetric projection, and (c) trimetric projection, depending upon the number of scales of reduction required.

	Axonometric projections - a technical overview
		This paper also presents two dimetric projections that are suitable for (tiled) computer graphics.
		Due to the coarseness of digital coordinates and the requirement that the edges of (chequerboard) tiles should match precisely, without any pixel overlaps or gaps, the skewing angles and scaling factors that game designers use are an approximation of the visually optimal proportions.
		The article argues that the word "axonometry" should refer only to the particular projection used by oriental artists (the so-called "Chinese perspective") whereas the generic term is "orthographic projections".

	Rulers for making axonometric projection drawings - Patent 4166322
		An axonometric projection drawing can be made with the use of the ruler from a plan view and a front or side view drawn by orthographic projection and placed on a drawing board as arranged in the orthographic drawing.
		Indicated on the surface of the ruler is an axonometric projection drawing 1 of a cube.
		After an axonometric projection drawing has been schematically made by using the ruler in the foregoing manner, details are constructed with lines drawn in the directions of the main projection axes OX, OY, OZ of the axonometric projection drawing 1 on the ruler.

		A parallel projection is one in which coordinates of the points of an object are transfered to the viewplane along parallel projectors (e.g., lines.) The edges of an object that is projected in parallel have the projected edges preserved and geometrically similar.
		A perspective projection is one in which coordinates of the points of an object are transfered to the viewplane to projection coordinates along projectors (e.g., lines) that vanish to a center of projection (COP)(sometimes called a vanishing point).
		The trimetric projection is a generalization of the dimetric projection.

	CS 4465, 3/19/04
		We categorize projections as parallel or perspective depending on whether we specify a view direction (with a viewer "infinitely far away") or a fixed view position.
		In the parallel case, we call the projection orthographic if the projection plane is orthogonal to the view direction, and oblique otherwise.
		The general case in which no principal face is parallel to the projection plane is called an axonometric orthographic projection (which includes both the dimetric and isometric as special cases).

	Isometric projection Information
		It is a method for the visual representation of three-dimensional objects in two dimensions in which the angles between the projection of the x, y, and z axes are all the same, or 120°.
		A problem with isometric projection is that because the lines representing each dimension are parallel on the page, objects do not become larger or smaller as they extend closer to the viewer.
		It should therefore be noted that this variation of isometric projection is more accurately described as a form of dimetric projection, since only two of the three angles between the axes are equal (116.565°, 116.565°, 126.87°).

		It will first be understood that an isometric projection is a special class of axonometric projection that shows length along any of three axes as true length.
		For example, a dimetric projection will result if the projection plane is equally inclined to two of the principle axes.
		When the projection plane is unequally inclined to all three principal axes, a trimetric projection results.
