fiongogo commented 10 years ago

1分形简介(分形是自然界的几何学) 1.1 分形理论的提出和分形理论的建立(与传统的欧式几何学的对应) 1.2 分形的几何特征(整体与部分的某种联系) 1.2.1自相似性(Cantor三分集,Koch曲线,Sierpinski集合) 1.2.2自仿射性 1.2.3精细结构 1.2.4分形几何与欧式几何的区别 1.3分形的测量 1.3.1标度 1.3.2分维 (D=lg(N)/lg(K) N为产生的图形,K为减少的倍数)(统计自相似的分形--盒维数) 1.4大自然中的分形(从严格的意义来说,分形是变化到无穷小的尺度才产生的,自然界的分形特征只存在在某些层次中) 1.5 分形是一种方法论(时间,空间,纵深,分形与混沌) 1.6 分形与计算机图形学 2分形图的递归算法 2.1Cantor三分集的递归算法 2.2Koch曲线递归算法---------------------------------有疑问(相对跟绝对的关系) 2.3Koch雪花算法 2.4Arboresent肺算法--理解x*cosa的意义

I think Mr. Doobs's GLSL sandbox site (gallery: http://glsl.heroku.com/) is worth mentioning, because it is a nice way to do quick experiments with fractals - rendered with full GPU-acceleration.

Here is a test with a 'Noir' Mandelbulb: http://t.co/PaBdK2DP Here is another test with a self-organizing system: http://t.co/VBgqXsDR

Another similar site is WebGL playground (gallery: http://webglplayground.net/gallery) - which allows for even more generic programs.

Here is a test with a Ducks fractal: http://webglplayground.net/saved/C8bszjTKKF

(I was reminded about these sites, because I just saw Visual posting some pictures using mrdoobs GLSL sandbox (http://www.fractalforums.com/images-showcase-%28rate-my-fractal%29/mrdoob%27s-glsl-sandbox/msg38709/#msg38709 :-))
