Puppy Ray is a ray tracing filter included in recent versions of Project Dogwaffle. It can run in the graphics processing unit (GPU) of a computer. I have recently acquired a new machine which allows me to better utilize the GPU. Here are my first two experiments running Puppy Ray in the GPU.

The first is a night scene. I have a particular liking for such images perhaps because I have spent so much time living in northern latitudes where winter nights are so long. I also like the bluish cast common to snowy scenes and the contrast between dark and light. And the lack of illumination can make successfully putting together a pleasing image can be a challenge.

Then one when the sun is up, fjords. Water planes processed in Puppy Ray are semi-transparent, allowing for more realistic rendering; i.e. you can see down into the water. The refraction index of the water as well as wave height and frequency can also be fine-tuned.

Here’s my latest experiment in combining the best features of Howler and DAZ Bryce. An arctic coastline, perhaps Greenland; with the familiar Flying Moose Aviation de Havilland Otter to indicate scale.

The mountains were rendered in Howler. I really like the degree of control one has in developing the texture, or image map, afforded by the use of an image editor such as Howler. Howler’s 3D Designer has two adjustable light sources which can be of different colors, typically orange and blue shades, resulting in very realistic lighting.

The seaside rocks and water surface were rendered in Bryce. I was not 100 percent successful in integrating the two images; a bit of tinkering will be required the next time to improve the results. This image is a study or sorts; I want to make a similar scene depicting the houses typical of coastal Greenland with a whale breaching in the foreground, and improved floating ice.

Another example of the amazing landscapes which you can make with Dogwaffle Howler. And an unknown something in the air over the mountains.

Another new toy! Twisted Brush Tree Studio from Pixarra. More thanks to Philip Staiger at thebest3d.com for telling me about it. With Tree Studio you can quickly create 2D trees of several deciduous and conifer species.

A few trees made in Tree Studio added to the recently-posted image of a de Havilland Otter flying over snow-covered mountains gives it an entirely different look and feel. With a bit of work you would have a very nice forest at feet of the mountains. Tree Studio allows you to adjust the colors of the leaves as I have done here so that the birch trees can be in their autumn colors.

For added realism a few of the png tree images generated by Tree Studio have been warped with another application.

Here is a screen shot of Tree Studio. The leaf color had been changed from the standard green to yellow. Tree Studios works with layers. A layer for the background, a layer for ground cover if, a layer for the trunk, a layer for the leaves. So that trees in the foreground will appear more realistic I suggest deleting the ground cover layer and adding another leaf layer behind the trunk as in this screen shot.

Further exploring Howler’s capabilities I rendered the very same landscape in Puppy Ray GPU as was shown in the last post, having been rendered in 3D Designer. Oh my! Taiga forest, I lived there.

Here’s a de Havilland DHC-3 Otter (which you have seen before), operated by mythical Flying Moose Aviation of Talkeetna, Alaska, flying over a snow-covered mountain range. While Dogwaffle began as a 2D, raster-based paint program, Howler can model landscapes with multiple ray tracing utilities. This image, of stunning, almost photo-realistic quality, was rendered up in the 3D Designer utility. 3D Designer also has the ability to insert localized cloud formations of several types into your image. In this example you can see the leading edge of an approaching snowstorm just beyond the mountains.

Dogwaffle has an amazing array features – 2D, 3D, particles. There is also a large and growing number of video tutorials to help you figure out how to use them. Look here for more examples in the future including landscapes rendered with the Puppy Ray ray tracing utility.

A New Toy

Like most artists working with digital media I use several software applications. Sometimes I may use as many as six or seven programs to produce a single finished image; especially if it involves 3D modeling – whatever works to get the job done. One program I have used for quite a few years now is Project Dogwaffle. I began with the freeware version and was very impressed; it was also a lot of fun. There have been many updates over the years and I upgrade every so often. A few days ago I upgraded to the latest version, known as Howler. No single application does everything, but Howler is a very sophisticated, though generally easy to use program. In addition to the standard painting functions that you would expect you can also make animations. Special settings for “painting” foliage are also included and some time ago the ability to generate 3D terrains was incorporated.

I have been tinkering with my new toy and thought I you might interested in the results. There will be more examples and explanations of how I use Dogwaffle in conjunction with other software posted here in the coming weeks. I am always experimenting and trying to push the envelope of what can be done. My friend Philip Staiger who helped develop various versions of Dogwaffle will also probably be posting some of it and additional material at his website, thebest3d.com. He has also made some very good video tutorials. My thanks to him for his recent assistance.

As I said 3D terrain modeling has been a feature for some time and, like the other capabilities, it gets better with every new version. The ability to work both 2D and 3D in the same software makes some things much quicker and easier.

Here is the first image I worked up in Howler. I probably should not have put my copyright mark on it as I, more or less, slavishly followed the steps outlined in a video tutorial by Dan Ritchie who developed Dogwaffle. I really like how Howler handles fog.

To generate a 3D terrain you need a black and white image where the lighter the shade the higher the elevation; I call this a bump map. Here is a bump map for mountainous terrain. A simple, black and white, overhead image – think topographic map where the lightest shades are the mountain tops and the dark shades are lowlands. These are very easy to make by rendering plasma clouds.

Here is a screenshot of the same bump map inside Howler’s 3D designer filter. Notice the terrain is a light neutral color. On the right you can see a panel with some of the many settings you can adjust.

The next step is to apply an image map, a texture, to the terrain. This is a simple image map made by again rendering plasma clouds, adjusting the color and adding a rock pattern to make it more interesting and realistic. As with rendering plasma clouds this is quick and easy to do. For the sake of brevity I left out a couple of steps required to add the snow.

The same image map applied to the terrain bump map in 3D designer.

By adjusting a multitude of settings – elevation amplitude, illumination, point of view, etc., etc., etc.,  anyone can make a nice scenic view.

Here is another doodle I made. Except for the Northern Lights, which I made with other software, everything in this image was done with the Howler version of Dogwaffle on the same manner as outlined above. You can also make some very nice Northern Lights in Dogwaffle.

One other thing you might find to be interesting.

Here’s a fractal image I made some time ago.

After running it though the same process as above – I was curious what would happen – this is the resulting image with the illumination set to make the relief more visible.

I definitely recommend Dogwaffle to anyone, from beginners in digital arts, to professionals with many years of experience.

When making images I may use something I draw/paint from scratch, objects and landscape modeled and rendered with 3D software, or photographs I have taken – sometimes I make use of all three in one image – whatever works. I do a lot of experimentation. In this doodle of stark, high mountains I am trying to “automate” the irregular presence of snow rendered in 3D; so that the snow line is not just that, a line. I haven’t perfected the process, but I think I am on the right track.

In this case I applied a terrain image map which I made in the PD Artist version of Project Dogwaffle (which, by the way, has a very useful 3D terrain modeling filter) to mountainous terrain in Daz Bryce. I duplicated the terrain with a snow material. Repeatedly applying a variety of random variations (noise) in the geometry of the two terrains gave the effect I was looking for. A bit of post-processing produced a rather nice result.

An out-of-the-ordinary, simple, blue and white fractal suggesting a melt water lake and a river, or stream, in a valley between glacier-covered mountains. This image is rather odd looking, but strangely appealing, a fortuitous randomly-generated fractal. I doctored it a bit to enhance the appearance of ice and snow.

You can find this image on many items at one of my Zazzle stores. Search for “glacial lake.”
