What is 8k ?
8k is 8000. Or more precisely: 8192.
It is the number of pixels in a very large image. Large today,
very large yesterday, tiny tomorrow. It's all relative and
depends on who you ask and when you ask.
This is big for a 32-bit program. What do I need?
Dogwaffle can load or create images at 8k resolution. It's not
trivial, but it can do it. You'll want to reduce the number of
minimal and maximal undos, You'll wat to let the undo images
go to disk rather than to memory. You'll want to select the
maximum allowed undo memory. And you'll want to be on a PC
with 8 or 16 GB of RAM or more, and fast RAM, 2400 MHz or
better. It works on slower systems too, we've used 1100 MHz,
During rendering the GPU may go and get busy for a while. If
it takes longer than 2 seconds, WIndows may erroneously think
that it's dead in its tracks, stuck in an endless loop. You
will want to adjust the delay value for TDR (Timeout Detection
and Recovery) in order to prevent Windows from resetting the
GPU and crashing Dogwaffle pre-emptively.
Learn more about TDR here: http://www.thebest3d.com/howler/help/notes-on-TDR-Timeout-Detection-and-Recovery.html
Note: If you increased the TDR in the past, and it (PuppyRay
GPU rendering of large images) used to work before but now
suddenly stopped working, perhaps you had a Windows update.
Please be aware that Windows updates may reset TDR settings in
the future. If suddenly a rendering doesn't work even tough it
used to work fine in the past, you may need to re-check the
TDR delay's value.
What creates 8k images?
You might use JSplacement to create great displacement maps,
heightmaps, bump maps. You might start from scratch directly
in Dogwaffle, create an image of 8192 pixel in width and
height. Then render various items into it, such as grids,
plasma noises etc... and eventually render it to 3D in Puppy
You can import such large mages with Default Targa(!) as the
mode from File > Save
, or through the options in File
> General File Converter
for other file formats.
