Computer GeneratedAngular Fisheye Projections Written by Paul Bourke May 2001 There are two main idealised fisheye projections common in computer graphics rendering, they are the hemispherical and angular fisheye. They are two from an infinite number…

Fisheye projections from spherical maps Written by Paul Bourke May 2003, software updated January 2016 See also: Mapping a equirectangular projection to perspective The source code implementing the projections below is only available on request for a…

Angular 2 templates have a special let syntax that allows you to define and pass a context when they’re being generated. We have template: <template #template let-description="description"> <h2>My {{description}} template</h2>…

简单实现 鱼眼模式(Fisheye)和普通的透视投影(Perspective projection),一个很大的区别就是鱼眼的投影算法是非线性的(non-linear),实际照相机的情况是在镜头外面包围一个半球体,将场景通过半球体投影到画布上.大致如下: M x \ \ ______ M'_x' `-. ,' |\ `. / | \ \ / | \ \ | | \ | __________|_____|____\_________|_________ M" O 1 M: world positi…
