Ever wondered about those human figures you see in 3D modeled images?

Consumer priced 3D models of people still have a ways to go to reach photo-realism. Periodically, I like to try out the latest such model, to improve my skills with them and to check progress in the industry.

I’d like to get your opinions on where this typical 3D model, my work on her and my render need improvement. This version of my scene was touched up in Photoshop.

This is the popular Victoria 4.2 from DAZ 3D, as the ‘Vandra’ character:

DAZ 3D 'Victoria 4.2' - by jim coe

For those interested, some details:
What I used:
Victoria 4.2, Morphs++, the “Vandra” clothing and jewelry, posed and many morph target edits in DAZ|Studio 3, imported to Vue Infinite 7.5, all her materials (textures) edited in Vue, Vue ecosystem as background (1 tree variety, 1 bush variety, 1 underbrush collection), volumetric clouds, single tree (outside frame) to cast shadows on her face, Vue spectral atmosphere, 2 light sources (“sun” and 1 omni fill light), radiosity Global Illumination lighting solution, rendered in Vue. I also used David Burdick’s fine “SkinVue 7.4″ (a Vue add-on product) skin shader to improve her skin, lips, fingernails and eyes. I did some postwork in Photoshop to add hair detail, blur lip edges and such.

Most of my DAZ|Studio morph modifications were for the head shape, eyes, nose and mouth.

For those unfamiliar with this type of 3D modeling:
The base model (the latest Victoria version 4.2) can be heavily modified in the “DAZ|Studio” (my fav) or “Poser” software, using the many dozens of “morph targets” in the “Morphs++” DAZ software for DAZ|Studio.

That is, muscle groups, joints and body parts may be moved, re-sized, re-proportioned, etc. (in great detail) to create different poses, body styles (toned, fat, thin, glamour, etc.), expressions, gestures and such. For example, there are probably 20 morph targets for the nose alone – In addition to different pre-built make up, eye color, eye reflections, wigs and the like. Or you can do such details yourself.

SkinVue 7.4, in Vue, allowed me to also adjust skin imperfections, SSS (SubSurfaceScattering), Fresnel effect (differences in reflection at different angles), veins, texture, eyeball details and lighting, and more.

There are a number of problems with this model and render, which I’ll attempt to remedy in the next version – to improve my skills in this domain. How many can you spot?

Your opinions please on consumer priced virtual human state-of-the-art (or as close as I can get to it)?

avegrilw Sketchup   An easy first step into 3D

A real wall, not from Google SketchUp

Google “Sketchup” is available in a free or Pro version. It’s very easy to learn and ideal for making simple buildings and other rectilinear 3D models. It doesn’t work the same as other 3D sculpting programs, but nevertheless offers an easy entry point to the more serious 3D programs – without the steep learning curve.

And, the chances are that whatever 3D program you choose if you get serious about 3D models and 3D scenes can import your previously made Sketchup models (but that might require a few tricks). In such advanced programs you can add much more realistic materials and lighting to your Sketchup models and really spiff them up.

A 3D modeled scene

What if you wanted to try your hand at 3D Modeled Scenes?

Here is my workflow
[sculpt major 3D objects {or buy them online from 3D sculptors at DAZ.com, Renderosity.com or Cornucopia 3D}] —> [Import them into your 3D environment program. I use Vue 'Infinite'. Sculpt, texture and pose environment items. Light it all. Render to 2D, using a 'virtual camera' inside your 3D world]
—> [Do "postwork" in Photoshop {optional}] —> [Enlarge for poster use. Add titles/borders/copyright] —> [Compress to jpeg format] —> Upload to your favorite online 3D art portal – I use FineArtAmerica.com]

You might think of it as a combination of playing with dolls or models, like you may have done in your youth, and then photographing the results.

Getting started
If you’d like to get started in 3D scenes, you’ll first need a 3D “staging” “natural environments” program. That’s where you import your 3D models to, pose them, create or modify their textures and clothing, light them, create vegetation, atmospheres, water, terrains, etc. I recommend Vue Infinite (but it’s over $700). They do have less powerful versions to get you started for a lot less money – then you can work your way up to the top of the line “Infinite” version if you stay interested. There is even a free trial version. Vue is sold as a 3D modeling program, but its main strength is in the creation of the 3D environments – amazing photo-realistic environments with thousands of buildings or trees or rocks, robot armies in formations all the way to the horizon and other such Hollywood special effects type stuff (Vue can do animation, if you have the computer power and is used lately in major movies).

Silo 3D
Ultimately, you’ll want to sculpt your own 3D models to put into your scenes. For that I recommend a much less expensive 3D modeling program – Silo 3D. Note that 3D sculptors have very strong opinions on the best 3D modeling program and you’ll get people swearing by one or another and putting down all the rest.

But 3D modeling is a challenge and it can take a year or more to get good at it. So to start, most people who make 3D scenes buy their 3D models online (many 3D sculptors make a living selling their models online to non-modelers). You then import your models into a third (free) 3rd program – which is specialized at clothing and posing figures, setting facial expressions adding wigs and such (or texturing vehicles, etc.). I recommend the free ‘DAZ|Studio’ over the older ‘Poser’ (which has a dated and awful user interface).

Many people never do become 3D sculptors and just continue to buy their models – but it’s great if you can learn to do both. As you might imagine, being a good enough 3D sculptor to make photo-realistic human figures is no mean feat, so many (like me) make some 3D models themselves and buy others. Still, hundreds of people do learn to make photo-real human figures every year. Those of you who already paint or draw realistic figures and understand anatomy will benefit greatly from that.

Virtual photography
Once you have your environment to your liking, you have a virtual camera in there with which you select shots and render those out as your 2D artwork – a lot like photography. Unlike manual drawing, once you have made a 3D scene, you can take thousands of “photos’ in there from different points of view. In fact though – you usually have a point of view in mind before you start. And also unlike manual drawing or painting, you can always go back and change things or start a whole new version based on a previous project.

3D sculpting: Silo 3D: Save learning this for the last part of your 3D adventure – it’s quite challenging.

DAZ 3D (models for sale. Notice that each product, e.g. clothing tells you what “base model” it’s designed for, that is which human or animal figure you must buy first):
Most 3D models cost $2 to $30 – not too bad.
DAZ 3D

DAZ Studio (free) the program where you clothe and pose your models. many people stop here and render – but you’ll get much better results by exporting your DAZ models and importing them into Vue.

The 3D art portal (forums, community, store, galleries, etc) just for Vue, “Cornucopia”, and they sell models specifically for Vue.
