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

hi, did you adjust all the 2d variations, needed for flame fractals to 3dimensional functions ?

the shadow is quite good ( smooth )

but the 3d ifs does not use any of the variations am i right?

respect

oh, i see, perhaps if i have time, i implement some transformations and send them to you

what methods have you implemented yet to render those point clouds ?

have you tried to render them the same way the 2d fractals are rendered?

That would be great!
I'd love to try anything you come up with.


I'm not sure what you're asking here?

Basicaly the volume is 2- 3D gradient fields, one for intensity, one for color. Intensity is used to calculate a normal vector which always points away from the higher intensity values, the color field is just used for color. Any 3D point within the volume will return a normal vector, opacity value, and color.

Since the size of the data arrays has to remain relativly small (256^3 is about the max my computer will handle) I'm performing a linear interpolation from the closest voxels to get precise values for any 3D point.



Yes...

If your asking about projecting the 3D data onto a 2D array of "buckets", then rendering the 2D array like Apo does. The itterator does that 3 times, one projection along each axis.

For the 3D raytracer, the 3D data is evaluated much the same way, providing intensity and color values for any point within the volume, intensity becomes opacity and is also used to set the IOR for refraction (if used).
