Orthographic Views

Orthographic view
Blender memiliki 2 cara dalam melihat scene 3D
1. Orthographic view
2. Perspective view

Untuk dapat menggunakan view ini secara effectif, rekan – rekan perlu memahaminya

An orthographic view (or projection) of a 3D scene is a 2D picture of it in which parallel lines appear parallel. An additional property of such views is that all edges perpendicular to the view direction appear in proportion, at exactly the same scale.
Usually such views are aligned with the scene's primary axes. Edges parallel to the view axis disappear; those parallel to the other primary axes appear horizontal or vertical. The commonly-used orthographic views are the front, side, and top views, though back and bottom views are possible.

Uniform scale makes orthographic views very useful when constructing 3D objects—not only in computer graphics, but also in manufacturing and architecture.

Here's one way to think about orthographic views:
Imagine photographing a small 3D object through a telescope from a very great distance. There would be no foreshortening. All features would be at essentially the same scale, regardless of whether they were on the near side of the object or its far side. Given two (or preferably three) such views, along different axes, you could get an accurate idea of the shape of the object—handy for "getting the feel" of objects in a virtual 3D world where you're unable to touch or handle anything!

Dan berikut ini adalah tampilan orthographic dari tangga yang sama

Coordinate Transformations

Viewnya dari depan, atas, dan sisi kiri. Garis putus - putus menggambarkan sebuah ujung yang mana dalam real life akan tersembunyi atau tertutupi oleh sesuatu, seperti dinding samping kiri dari tangga. (pikirkan masing - masing view sebagai gambar X-Ray)
