Kraellin,

Here's basically the process.

In a 3D modeling program (such as Maya, Cinema 4D, Blender3D, 3DSMax,... etc) we model the object we want using various methods.

Now once we're done modeling, we can go and apply texture it much like we paint that object we modeled. Programs such as Maya (and consequently the rest) have texturing capabilities. The ability to use what we call "shaders" becomes a key role here. Shaders can simulate various materials, anything fr om clay to glass can be simulated using these shaders.

Once we're done, and we have lit the scene, we render it. Now this is wh ere you have the question:

All the render engine does is that it takes the given model / texture / shader information and then using several bajillion algorithms it calculates how light will bounce (or reflect) on the objects of the scene. Render engines, in the end, are able to make the objects look as realistic as a photograph, but also can make unrealistic images too. For example a toonshader can make images look like drawings or otherwise.

That's the real basic idea behind the render engine and 3D art itself.

Wikipedia has a fairly detailed article on a "render engine." Please note that this article does not discuss toonshaders (or nonrealistic rendering)

ok, so all these things have been split up into specialty programs. things have changed a lot since the 8 bit days.

Well, not necessarily. Most 3D packages feature all modeling, texturing, and rendering components. Although because 3D is such a large field, we split it up into parts to make life easier. This is true especially for studios where you would be assigned just the modeling, texturing, render and compositing separately.

The point being that it makes it easier to focus on one thing than various things. And so it happens that render engines are separately. They basically specialize in just rendering and nothing more.

so, i know there are some standard file types and such, but how easy is it to go from one modeling program to another light program to another texture program and then incorporate all those different file types into another render machine if each of those programs is made by someone else?

Very easy. Although remember, MOST 3D packages include the main parts: Modeling, Texturing, lighting, and rendering. You really don't have to move from one program to another at all. Now if by any chance you WANT to utilize a different program to do the modeling, texturing, and otherwise, you can always create a workflow. You can always use standard file formats (for 3D there are: OBJ, DXF, FBX, and others.) So nothing's really a hassle. As much as you may be sharing images using the JPEG compression, as long as the rest of the programs CAN open the files I save as, I have no trouble going from one program to another.

Some exciting updates happening to one of filters here. Dabber 0.3 (http://filterforge.com/filters/8420.html) hasn't been updated in a while with the necessary features I wanted to add. Now it's Dabber 0.7.

It includes the same Dabber feel but better.

Dabber 0.7 Features
+ Detailed coloring. Unlike the last version where colors were dabbed heavily, this version features a slider that lets you add greater accuracy to the coloring based on the image.

+ Control over color bleeding. A new slider adds very simple control over how the color (paint) behaves. You can make the colors blend more or not.

+ Detailed line drawing. Unlike the last version, this version gives you further control of the drawing part. The drawings can be more detailed OR less detailed. The lines can also be colored.

+ Many aesthetic changes. The previous version looked better at preview resolution although when rendered at large resolutions, things got a bit weird. I fixed that with this version.

The image below was rendered with the new version.

So, I had two thoughts in my head. Photoygraphy 3.0 IS INTENSE. Sometimes too intense, I think. IT works stylistically, but if you want something more subtle and more like a photo, it's really not the filter you'd want.

Several months ago I began constructing a "Kodachrome Filter." The goal was to simulate the signature 1940s Kodachrome look using FilterForge. As its basis I used some of the components I created in Photoygraphy 2.0, which resulted in disaster. I switched to Photoygraphy 3.0's color correction method and it worked better. Ok, well I totally forgot about it and just today, I came back to editing it for a 2011 release.

I still wasn't satisfied with the look. In the end, I felt like I was wasting time trying to make a specified filter that did one thing. Instead, I began deconstructing the filter to get something a bit different.

So what now? Well, I'm a big fan of analog photography. While I was REALLY interested in high-resolution digital photography, I also enjoyed using crappy cameras. Yes, I love point and shoot cameras with the worst possible lenses. People usually recommend me go Lomography buuuut those are just too expensive. I already have a nice Canon 60D (digital) SLR camera and I take tons of photographs with that. I also use my point-and-shoot but those are film; and film takes a while to develop. So I told myself, why not just make a filter that makes images look kinda analog?

After a couple hours of playing around with nodes, I hit something that I totally wanted. It's basically Photoygraphy 3.0 stripped bear minimum. It's got only 5 basic features (so far) and it probably won't have more.

The results are actually great. They do look like photographs from the 70s, 80s, or 90s. Success! What's the name for this filter? I'm just calling it Oldify for now. But that sounds lame and boring. I'll change it around.

I'll be attaching several examples below. Oh boy I'm excited.

This filter is really fast. Compared to Photoygraphy 3.0 we're talking serious speeds. The preview for this image took just 4 seconds to render. I guess it depends on the processor, but it should be blazing fast for everybody else anyway. By the way, I have the 2.66 Ghz Intel Core i7. smile;)

I swear, some of these photos I'm processing begin to look as if they were really taken with a crappy point and shoot camera. Almost scary how convincing some of these results are.

The place you're seeing, by the way, is Tsukiji, the largest fish market in the world.

Maybe this filter should be called "Point and Shoot."

I don't know. These photographs are making feel nostalgic.

The other thing about this filter is that you'll never hit nasty results with the randomizer. Unless you feed it a bad image, the results will always look decent and to expectations.

Maybe I should call the filter "Disposable" or something. I'm really just pondering about the name.

This filter, I plan, to release it early 2011. Probably the first week of 2011. smile;)

That's some burning incense in the picture below.

It has a couple features currently, will be adding more.

You can control bulkiness, saturation, scale, and I had to tie variation to it. This generator is slightly broken still. Tons of fixes needed.

nice. still a bit too 'stone' looking to be glass, but one can certainly see where you're headed. hope you get it. would love to see a good stained glass filter using an imported image!

The refraction ripples on the stained glass are cool, I never would have thought of that. The real problem is that the tiles are too uniform in size and shape. If you could somehow get them to shape themselves like the actual image, that would be awesome.

And what's with the sperm cells?

Did some interior modeling.

It's meant to be a capture fr om my dream at some point when I was 19 or so. This dream was about me going to a beautiful art gallery / museum of of some kind. After parting with my group of friends, I walked down stairs to this place wh ere a nurse came up from the distance of this hallway to me and said, "Don't worry, he'll be fine." I don't know what that meant to this day. I don't have a brother, nor do I think it had anything to do with my family.

Rendered with Octane.

Used the following Filters
Emme - Rough Wood Planks
Crapadillia - Rough Plastering

Somehow the normal map was flipped when rendering, will need to fix that.... There also seems to be some normal problem with one of the cylindrical rooms.

Rendered with Octane again. I sat with this one for 30 minutes. The previous image was left to render for 1 hour and 9 minutes.

Octane basically works so that you can pause the render when you feel like it's reached a good point. I just ran out of patients so I paused the render. So there aren't as many "samples" as it would on the previous image.

very cool on that room. what is that 'bubbling' in the floor on the top one of the two? and the second one looks great until you click on it for the larger view and then it looks grainy. still, this stuff just keeps getting better and better. those renders 20 years ago would have taken days to do and not been that good.

I return! I was getting a bit busy for a while. I haven't updated much of my filters as I said I would sometime ago... but anyway.

Point and Shoot now has a small addition. It now has chromatic aberration just for the heck of it. Not that its needed, but it does make the image look just slightly... pretty.
