UPDATE – Cubic Lens Distortion Pixel Bender shader for AE (with scale & chromatic aberration

cubic lens distortion & chromatic aberration



If you haven’t seen my previous post yet, here is the Syntheyes’ Cubic Lens Distortion algorithm ported to Pixel Bender.


New Features

  1. Scale factor : works exactly as Syntheyes Scale Lens Workflow (v2)
  2. Chromatic Aberration : based on Martins Upitis‘s GLSL posted here (v2)
  3. Blue/Yellow Chromatic Aberration based on Dorian modification (V3)



Download

  1. Download ft-CubicDistortion.pbk here : http://aescripts.com/ft-cubic-lens-distortion/
  2. Place it in your “Support Files” folder (which is in your AE install folder)
  3. Launch AE
  4. Look for the effect called Cubic Distortion

Source Code

just download the file at http://aescripts.com/ft-cubic-lens-distortion and open it with your notepad application

GLSL Cubic Lens Distortion with chromatic aberration in Blender Game Engine

Introduction

I received a mail the other day from Martins Upitis, who asked me really nicely if he could use my Cubic Lens Distortion Shader code into one of his GLSL shader. He was asking me if he could copy & tweak it a little bit. That was really funny to me since Martins is probably the guy who made me wants to learn shader in the first place after seeing one of his first shader he posted on blenderArtist, and also because he didn’t figure I was the same person asking him thousand of noobs questions on that same forum :p .
Of course I was so proud that I said yes, and he made it look so coooolll !!!

Anyway I encourage you to go check out his post on BlenderArstists.org here : http://blenderartists.org/forum/showthread.php?t=175155&highlight=lens+distortion

His shader create vignetting, chromatic aberration, cubic distortion, depth of field, and a really smart animation texture based on 1bit alpha store in each RGBA channels (which gives a lot of frames – so smart)… it looks really great !

Blender File : http://www.pasteall.org/blend/1425 or mirror on this blog

controls:
buttons 1 and 2 enables post-process effects (vignetting, noise, edge-blur, and a new and awesome lens distortion filter, made by Francois Tarlier, and slightly modified by me).

Up/Down – shrink/grow the snowflake
mouse wheel up/down – chromatic dispersion amount

numpad:
7/4 – lens distortion coefficient
8/5 – cubic distortion amount
9/6 – image scaling amount
