I've loaded this background image and clicked calculate 3D and its not visible. Here's a screenshot

Some nice images I must give UF trial  another try.

C is calculated like this:
Code: [Select]
vec2 c = 1.1*vec2( 0.5*cos(0.1*time) - 0.25*cos(0.2*time), 0.5*sin(0.1*time) - 0.25*sin(0.2*time));
Just check the shader I linked in a first post.

this is just me trying to sort it out, I may need this as reference later ;)

UTF-8 seems to be enabled properly for the server and in headers to the browser

are converted to these...

but this is only done in getLegacyPMAttachmentFilename() if we're looking up files attached with an old version that doesn't have a hash value associated with the filename

getPMAttachmentFilename() "encrypts" attached filenames using sha1(md5(filename)) hash value, that is used as attachment_id to reference the attachment, the name displayed below the image is retrieved from the database using that reference

try hovering over the icon in my post above, it will show you the URL with IDs, the icon should have the filename next to it as is was when uploaded

clicking the icon will show you the filename that is stored at that reference ( rm-test.png ) select save and the file will have that filename when downloaded to your computer

So the correct filename is there, with special chars, and the reference hash is there or it wouldn't download  ???

can you describe how c parameter is moving on the parameter plane?

That speckly stuff is bad DE (  the  distance estimation calculation aint too good).

As a general rule :  The more you hybridize the more likely the standard DE calc being used will not fit so well.

Reducing Raymarching step multiplier on Render Engine tab may help (but increases render time).  With some hybrids you need to find parameters and location that produces a good quality, and then explore around that region for an image. 

You can always Save your settings to clipboard and post them here or at the Mandelbulber facebook site, and I will advise you if i can:)

Yeah, I heard about the effects during meditation too, but I don't know what to make of it, really. I created a sierpinski merkaba myself for my shapeways shop (with free download): https://www.shapeways.com/product/SFZVCLE6N/sierpinski-merkaba-ii-16-cm. It's suppossed to have some pretty interesting energetic properties as well, but I don't really know cause I never printed it.

Your work is beautiful, keep it up!

Oh, I like that !   I made the brass merkaba and  3 Octahedra   from 1mm thick sheet , so they're hollow.
I saw the 3 -Octa in an Escher print and thought "y'know, it's not that much harder than the 2-tetrahedra" .
That was about 40 years ago. Nobody had pc's, and ...well, it was the Stone Age compared to now  (maybe
 the Brass Age ).  It's really amazing what can be done now  :thumbs:
