Howler development is on hold (we hope just temporarily)

 It's been a rough few weeks. There was some robbery/theft and there was a laptop that died, lost the motherboard. Replacement cost $900 or so. We don't have it.

Howler development is on hold, for now, hopefully not too much longer. We got a temporary replacement PC that will have to do, somehow. Thanks to a handful of caring artists-at-heart for helping. During the Olympics, it's nice to have friends that help carry the torch :-)

Also, if you feel inclined to support the mission, be it for the books (Silver Squirrel and more), or the software (Howler), here are two ways to support Dan:



You can contribute small donations in support here:

 -----------  Back to the top --------------

Labor-Day and Back-to-School (-home-school?) Promotion

  Use this discount code for 40% off the regular price on either of these:

                Discount code good through September 1540SCHOOL21

- PD Howler 2022
- PD Howler 2021

- PD Artist 2021

Of course you still can request and use an even better discount coupon for 50% off for upgrading from any prior version, including sidegrades from PD Artist and non-Dogwaffle tools, 3D tools too. Make Howler the companion tool. Contact Philip at for the discount code if you don't have one. Tell us which version you are using (or have used in the past).  Or also check Dan's direct website at to see if there's similar or even better discounted deals waiting for you there.

And of course, one of the best ways to support the projects is by tell friends and family about Dogwaffle, also teachers in various types and grade-levels of schooling, especially if they have a computer lab with Windows PCs. Thank you for placing an order on here or at Daz3D or Steam or other platform. It may not be the latest greatest version in all places but it still will make a great companion to your arsenal of digital tools.

New Dogwaffler of the Moment:  Mike Stone

This artist from the Chicago area has created cover art for music CDs for a few musicians and a bunch of other interesting artwork and has been featured on TV. Check his art gallery and learn more at

Start here:

Mike also does animations and loops, using a variety of tools.

Here is a video we recently created to show how to repair some bad details or frames in a video.

Geek Talk: Analytical Upscaling (aka Supersampling)

Analytical Upscaling or Supersampling is a tool that lets you upscale an image while maintaining the original 'sharpness' and adding new detail that appear crisper than if the image was simply resampled the traditional way.

It works without having to be on-online, i.e. we have implemented the code into Dogwaffle to run locally on your PC. If you have a PC with a nice high number of CPU cores, such as 8. 12. 16 or even (bless your heart) more, you will want to keep an eye the Task manager, showing each of the logical cores. You'll see them flare up to very busy ;-)  ---
It's multithreaded. But it's not on GPU, and it uses block matching.  In this case Dan chose to use a C++ class to ease the block matching burden instead of working on hardware.  It's already a complicated problem.

It performs this image re-calculation by using the existing details found in the current image to construct a newer, higher resolution image. Imagine the image sliced into small squares, in similar analogous way to what you may remember from the motion estimation side (motion prediction module - see motion prediction mania! ). Each square is looking for details on shapes and colors, information across neighboring squares up to a set distance which you can control. The farther the distance, the more it thinks and looks for best solution, so the longer it will take to finish.

You can turn the image into double-size in this manner (x2), or even x4 (really 16x the original number of pixels, as it's doing a 4x4 resizing). Be mindful of the dimensions of the current picture, you might run out of memory quickly. This is more intended for small images needed at larger size, sich as when you crop out a small subset of an original image.

In the future there might be some extra safety steps to avoid running out of memory and crashing. For now, be careful. :-)

This works pretty well because of the fractal nature of images: Some smaller details resemble larger details in the same image.

Just One More - 

Long ago we were big fans of Carrara. Remember? We still are, mind you, but the program, Carrara, hasn't gotten much attention in recent years, it seems like the focus at Daz3D is on DAZ Studio. 

Still, Carrara has a great history, an evolution, was touched by Kai (as in Kai's power tools) for the novel interface, shared by Bryce, Poser, and Canoma.... the latter of which was acquired by Adobe. Perhaps we are starting to see any of this in Adobe's newer 3D developments?

Either way, this all prompted me to review my aging and old Carrar page at

Yes we know, some of the links are old or broken, or in the words of our friend musician, old but not forgotten.

Check this section too: Atomic City

We recently updated that page to replace all quicktime or Flash videos with mp4 versions. Remember the html5 revolution? It seems to far away now. But the impact it has had on multimedia, exceptional.
