Orthographic projection - Wikipedia
An orthographic projection map is a map projection of cartography. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective (or azimuthal) projection, in which the sphere is projected onto a tangent plane or secant plane. The point of perspective for the orthographic projection is at infinite distance.

投影有正交投影（Orthographic Projection）和透视投影（Perspective Projection），以一个正方体线框举例，正交投影后平行线仍然是平行的，而透视投影则会产生近大远小的效果，且原来的平行线会交于一个点：. 回顾一下之前讲过的顶点变换过程，可以看到投影矩阵 ...
The Perspective and Orthographic Projection Matrix
The aim of the orthographic projection matrix is to remap all coordinates within a specific 3D space bounding box to the canonical viewing volume—a concept introduced in Chapter 2. Imagine this original box as a bounding box encompassing all objects within your scene.
The Perspective and Orthographic Projection Matrix
Unlike its perspective counterpart, the orthographic projection matrix offers a different view of three-dimensional scenes by projecting objects onto the viewing plane without the depth distortion inherent in perspective projection.
投影算法（一）：正交投影矩阵（Orthographic Projection Matrix…
投影矩阵主要分为两种： 正交投影、透视投影，这篇文章主要介绍的是正交投影矩阵的推导，下一篇再介绍透视投影. 原理. 构建正交投影矩阵相对于透视投影来说要简单很多，只需要将 视图空间（eye space） 的坐标线性的映射到 NDC（normalized device coordinates） 坐标中： (Xe,Ye,Ze)=> (Xn,Yn,Zn)\in [-1,1] 左图为视图空间坐标系，右图为NDC坐标系. 只需要把 (Xe,Ye,Ze) 每个轴缩放到充满NDC立方体，然后移动到原点即可. 推导. 最左边的矩阵就是我们 …
The Perspective and Orthographic Projection Matrix
Make sure you're comfortable with matrices, the process of transforming points between different spaces, understanding perspective projection (including the calculation of 3D point coordinates on a canvas), and the fundamentals of the rasterization algorithm.
Orthographic projection What’s the projection matrix in homogenous coordinates? Image World (x, y, z) →(x, y)
A projection is a transformation that maps from a high- dimensional space into a lower -dimensional space. We will look at some common projections…and then we will discuss projection within WebGL
Orthographic Projection The simplest form of projection, is to simply project all points along lines parallel to the z-axis. This form of projection is called orthographic or parallel. It is the common form of projection used by draftspeople for top, bottom, and side views. The advantage of parallel
8.2 - Orthographic Projections — LearnWebGL
2016年3月8日 · This lesson will describe how to create an orthographic projection and the mathematics behind its 4-by-4 transformation matrix. The createOrthographic() function ¶. The function createOrthographic() in the Learn_webgl_matrix.js module creates an orthographic projection transformation matrix.
