END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

It's stereo demo:

If your eyes are not so widely apart, try this version:

Which format I should use for this? I mean L-R, R-L or anaglyph? I used L-R schema but in this case I can't make distance between centers of images > 2.5"

A couple of images:

Hi,

I have also written some realtime rendering code; have a look at the other thread behind this link... (sorry to hijack your thread

 - ld

very cool, nice and serene. Good music to match.

The 3d isn't popping out as much. What field of view are you rendering? Looks large, given the spherical looking near plane clipping.

How do you render left & right? Simple side-step or asymmetric frustum?

I find 3d effects are best when rendering approximately the field of view of the display device. And trace rays for left & right eye through the pixels of the projection plane / screen. That results in slightly different directions for same pixels in left & right eye, hence the asymmetric.

Nice texturing / coloring. Care to share your approach?

I use this approach:
// vertex shader
void main(void)
{
   gl_Position = ftransform();
   gl_TexCoord[0] = gl_MultiTexCoord0;

   coord=gl_TexCoord[0].xy;
   coord.y-=(eye-0.5)*0.08;  // parallax far
   from.z+=(eye-0.5)*0.012 // parallax near
   vec3 Dir = normalize(Target-Eye);
   vec3 up = Up-dot(Dir,Up)*Dir;
   up = normalize(up);
   vec3 Right = normalize( cross(Dir,up));
   dir = (coord.x*Right + coord.y*up )+Dir;
}

// fragment shader
void main()
{
   gl_FragData[0].xyz= trace(from,dir);
}

Also a couple of pictures:





It is mandelbox, scale=1.5 c=0.1

     for (i=0;i<12;i++)
   {
      p.xyz=boxFold(p.xyz);
      p/=max(dot(p.xyz,p.xyz),0.5);
      p*=scale;
      p.xyz+=c;
      if(i==2)
         p.xyz+=p.zxy;
     }

I've made a true 3DBD (MVC format). It's here: http://www.sanbase.org
