Isometric drawing is a form of 3D drawing, which is set out using 30-degree angles. It is a type of axonometric drawing so the same scale is used for every axis, resulting in a non-distorted image.

120 degrees

The isometric drawing is drawn using 100% true length measurements on the height, width, and depth axes. However, in isometric projections the height, width and depth are displayed at 82% of their true length. In isometric projections the object is first rotated about the Y axis by -45 degrees.

Isometric – all dimensions are the same scale. Dimetric – di=2; 2 axes/dimensions foreshortened. Trimetric – tri=3; 3 axes/dimensions foreshortened.

The three types of axonometric projection are isometric projection, dimetric projection, and trimetric projection, depending on the exact angle at which the view deviates from the orthogonal. Typically in axonometric drawing, as in other types of pictorials, one axis of space is shown as the vertical.

Definition: 1) Isometric 2) dimetric 3) trimetric Term: Isometric drawing Definition: A three-dimensional view of an object in which the object is tilted in relation to a picture plane (rather than parallel to the picture plan, as with an orthographic drawing).

Isometric (meaning “equal measure”) is a type of parallel (axonometric) projection, where the X and Z axes are inclined to the horizontal plane at the angle of 30⁰. The angle between axonometric axes equals 120⁰. An isometric sketch is sometimes referred to as an isometric view or isometric drawing.

Also: dimetric crystallography. relating or belonging to the crystal system characterized by three mutually perpendicular axes of which only two are equal. 2. of, relating to, or shaped like a quadrilateral.

What is the main advantage of Oblique projection over the isometric projection? Oblique Projection represents a simple technique of keeping the front face of an object parallel to the projection plane and still reveals three directions of space.

objects can look distorted if careful choice not made about position of projection plane (e.g., circles become ellipses) lack of foreshortening (not realistic looking)

An oblique sketch puts more focus on the face or front of an object while an isometric sketch puts more focus on the edge of an object. To achieve this, oblique sketches are usually drawn using a 45 degree angle to render the 3rd dimension while isometric sketches are drawn using a 30 degree angle.

Isometric Projection

• Used for: catalogue illustrations. patent office records. furniture design. structural design.
• Pros: don’t need multiple views. illustrates 3D nature of object. measurements can be made to scale along principal axes.
• Cons: lack of foreshortening creates distorted appearance. more useful for rectangular than curved shapes.

Isometric drawings are commonly used in technical drawing to show an item in 3D on a 2D page. Isometric drawings, sometimes called isometric projections, are a good way of showing measurements and how components fit together. Unlike perspective drawings, they don’t get smaller as the lines go into the distance.

1) Draw a horizontal line. 2) Mark one corner of square at the center of line ‘D’ in fig. 17 3) Draw two lines as shown in the fig at 30° to the horizontal line. 4) Select isometric scale as shown in the previous example.

An isometric projection results if the plane is oriented so that it makes equal angles (hence “isometric,” or “equal measure”) with the three principal planes of the object.

The reason to draw at 30 degree is because at 30 degree all the three axis vary in the same proportion. That is why the figure looks perfect. All the three planes( ie X, Y and Z) are equally inclined to each other at an angle of 120 degrees to each other(ie 360/3=120).

1 : of, relating to, or characterized by equality of measure especially : relating to or being a crystallographic system characterized by three equal axes at right angles.

Isometric video game graphics are graphics employed in video games and pixel art which angle the viewpoint to reveal facets of the environment that would not be visible from a top-down perspective or side view, thereby producing a three-dimensional effect.

Sometimes called “isometric”, incorrectly in case of these games. Diablo II is a rare exception – it is a 2D game (drawn of flat sprites) that has somewhat perspective projection (if enabled). Diablo 3 and Starcraft 2, though, use a true perspective projection, with objects being smaller the farther they are.

Unfortunately, isometric is not pure 2D. In that case, you’ll really want to use models anyway. Of course it will be easier in 2D. Keep in mind nobody forbids to use a 2D collision representation with a 3D isometric or somewhat-3D visualization.

Diablo 3 uses an isometric camera like its predecessors. The development team considered using a “more modern” camera for the action RPG but director Jay Wilson said he rejected the idea.

Brevik originally thought of the concept while in high school in the San Francisco Bay area. He lived at the base of Mt. Diablo, which was near him. He didn’t know any Spanish, but the mountain inspired the name.

Basically everything in the game is a pre-rendered 2D sprite, but the actual characters (Heros, Enemies, Bosses) are all 3D assets. The maps are all 2D sprites.

A 2D isometric drawing is a flat representation of a 3D isometric projection. Distances measured along an isometric axis are correct to scale, but because you are drawing in 2D, you cannot expect to extract other 3D distances and areas, display objects from different viewpoints, or remove hidden lines automatically.

Pokemon [at least the versions I’m familiar with] use isometric rendering.

Via Game Informer, a new batch of screens shows the magical RPG has had a makeover, switching from a style highly evocative of Stardew to a more distinct, detailed, isometric style that still retains that charm and pleasant color schemes.

Filters. (art, cartography) A type of visual perspective in which all dimensions parallel to the three principal spatial axes are shown in their true proportions.

Isometric Tilemap works with 2-dimensional sprites, and it relies on correct renderer sorting in order to create the illusion of a top-down isometric view. We need to make sure that the tiles that are further away from the viewer get painted first; and those that are closer painted on top of them.
