3D Circulatory System / Veins and Arteries

          The Human Cardiovascular System                      

We have developed a high resolution 3D human cardiovascular system, consisting of no less than 680 parts, with full nomenclature so as to make the single parts easy to identify - they can be found either in the optical interface or on the objects list.

This elaborate system includes all major and minor blood vessels as well as some peripherical ones, the veins and arteries of the head and the brain are included, too.

As the heart is pumping at the center of the circulatory system, you can order either this system with or without the heart - whatever suits you best. The file fits our anatomy sets (muscles, skeleton etc.) P1-P3 in size and is included as described here, in teh P1 full (Skeleton, Muscles, Organs)) Anatomy Set.

Available for direct download in formats 3dsMax, Maya, .fbx, Wavefront .obj , compatible with Softimage XSI, Cinema 4D, Lightwave, more - now even partially useful in several CAD applications.

- Most people know about the basics of the Circulatory System; that the Arteries transport freshly oxigenized blood which the heart draws from the lungs into the remotest parts of the Human Body and that the Veins transport the "exhauste", oxygen-drained "blue" blood backwards into the heart onwards into the lungs where it gets reoxigenized - so far, so good.

Surgeons know (I almost said "bloody well") that the Veins are NOT blue and the Arteries are only red on the inside - actually, the vessels, like the nerves and other bodily features, are sometimes very hard to tell apart at first glance and this is exactly why a good surgeoan is also a good anatomist - plus he must have the hands of a pianist and be professionally paranoid... "nicking an artery" is among their worst nightmares, for a reason. There are blood vessels, actually quite a couple of them, the "nicking" of which can lead to almost instant death, irreversibly. The Romans knew exactly where to use their Gladius (go for the neck or the groin), now this is what a surgeon will do his best to avoid but then a scalpel is very tiny - the Gladius was very broad AND sharp so as to sever as many blood vessels as possible in one go - oh I apologize, this is really not a history site. Still, it should be more known in our day of constant Police Action Movies, that it is rather hard to shoot someone in the upper leg and make usre he does not bleed out befrre an ambulance is even half way there. So, does everybody know where the Femoral Artery is ? ThatÝs good. Then of course there is the small complication that many human bodies are pretty much unlike each other, a fact any surgeon understands but (to our chagrin) many engineers have no patience for...

Back to Animation, one problem is always in existence with elaborate collections of *vessels*, which are after all similar to pipelines - though they interconnect a lot more and have an erratic way of curving behind bones, muscles and what not... the problem is the curvature itself mainly. In the Human Body Anatomy or rather itÝs 3D equivalent, this applies mostly to Blood Vessels and Nerves. They get very curvy and they get very peripheric and rather tiny, and one simply has to draw the line somewhere as the Animator will not be overly happy with a million polygons more for even nicer curves - as animations consist of at least 25 renders oer second, files that render a third more slowly will not be his favorites so we keep it on the scarce side with the curvature wherever possible - now that is one thing. It gets bad when we receive calls for even "slimmer" file sizes and have to reduce the 3d anatomy, this is where pipelines always suffer first and show up where the limits are... so we cannot go for gold in the peripherical parts of the blood vessels though we would really like to - at least in parts of the body. We cannot as a default but if you need such a file because your work is more of the scientific than the spectacular sort, then please tell us so and we shall see what we can do.
