Thanks for spotting the bugs that a spell checker and two read-throughs failed to pick up. :) Re: Can a Big Lens really turn your iPhone or iPad into a professional DSLR camera? 12 Years Ago by Fortinbra I have friends that hate it when I do this to them.

Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd Alright, I've coded the example at NeHe Productions (awesome site!) and I have got some wonderful results with the CG Vertex Buffer (Lesson 47). I familiarized myself with the code and I know how to make some basic transformations. ... Now how do I make it distort light instead of objects? Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd I think I might have to use Fragment Shading (Pixel Shading). I'm looking into this now. UPDATE: I went through your message once more, you already suggested to me to use "a pair of vertex and fragment shader". My bad. Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd I've just found this website whose source code uses only the glut library and was able to create effective distortions! [url]http://local.wasp.uwa.edu.au/~pbourke/miscellaneous/lenscorrection/[/url] I haven't examined the code yet, but this is still great news! Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd Alright! I've got what I wanted. I've hacked together some functions that will help to distort the screen with sine, square, and arcsine functions with minimal difficulty. This was an odd mixture of NeHe's lesson 36 (Radial Blur) and a link I mentioned earlier. Here's the header: [CODE]#ifndef DISTORTION_H_INCLUDED #define DISTORTION_H_INCLUDED … Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd To clear things up, I would be able to solve the 2 complications I listed once I knew how to render an orthographic view. As things turn out, I have done it! These are the updated functions: [CODE]void Transform(int i, int j, double *ix, double *iy) { double x, y, xnew, ynew; double r, theta, rnew, thetanew; x = i / (ScreenSizeX/2… Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd Hey everybody, Yup, I've done it. I've even compacted it so you can get the distortion effects with just one function call. This is the header (called Distortion.h): [CODE]#ifndef DISTORTION_H_INCLUDED #define DISTORTION_H_INCLUDED #define SIGN(x) (x < 0 ? (-1) : 1) #define PID2 1.5707963268 GLuint EndTexture; GLuint EmptyTexture() {… Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd Hey guys, I've spent a few days trying to find a solution by trial-and-error. I get close, but the distortion is not seamless. Let's assume the 'object' mentioned below is causing distortion. Let me try to explain some things I found out... This 3D Distortion method would be to get a texture from a 3D space, and render it at that exact same … Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd I now have some code that works perfectly on my application. This is some new code: [CODE]void wRenderToTexture(GLfloat CtX, GLfloat CtY, GLfloat Radius, int &StartX, int &StartY, int &Size, int &d) { int ScreenMod = (int)(ScreenSizeX * 0.909f); //727 int StX = (int)((CtX-Radius+1.0f)/2 *ScreenMod) +36; int StY = (int)((… Re: OpenGL Lens Distortion 13 Years Ago by Weird Nerd I now have some code that works perfectly on my application.

This value might change with the screen ratio, but I was unable to check that. The XAlign is affected by both Screen Size and Depth. These are my findings for my 800x600 resolution … Re: OpenGL Lens Distortion 5 Years Ago by WaszStary Hey there - I feel a bit bad resurrecting such an ancient thread but I must say that the above piece of code from Weird Nerd is amazingly done and appears to be the only solution I've been able to find on the web that "just works" right after inserting into any code and running it - without any need for headers. Great work indeed!!! I'…
