Another challenge! Real or fake heart?
Some of you got stumped by the last challenge. This one isn’t any easier.
Is it a photograph, a 3D model, or digital art? Click “continue reading” at the bottom for the answer.
It’s actually a combination of using Photoshop and Maya (a 3D program). Done by Michael Bengtsson.
Here’s how he did it.
The tecnique is that I constructed the hole image in photoshop first. That is…In different layers i painted up specular/ static shadow and highligt and so on to make sure that it fitted all together before I even started up maya. This was done partly from using photographs and lots of cloning and then I also painted in some extra details.
When I was finished with the Image I projected it on to a simple plane in maya. The projects deadline didnt allow for good uv-mapping so working with projections was the obvious choice. After that I modeled the geometry…kind of like when you are doing imagebased rendering. For this particular project I knew that I was never going to se the other side of the heart, therfore it was sufichent with modeling from on side, so I could don 180 sweep around it atleast.
The heart now looked great in a stillframe… but not in animation…it was to static. To make it look good in animation I also whent in and constructed a displacement map/a bump map and a specularmap. The I used a selfconstructed hdri image to get the sharp reflections on the heart. An occlusionpass were also done to get the final touch during the animation sequence.
Wow! I managed to guess the other ones right, but this one stumped me. Love the website by the way.
That is an unbelievably gorgeous animation. Perhaps the best I’ve ever seen. Are you sure it’s not real?
To be fair, the artist does say that he used photos in producing the image (not that there’s anything wrong with that). I assume that’s partly why the detailed textures are so great.
Ben - I forgot to mention that he also used photographs in the post. So it turns out it’s a perfectly executed use of all three mediums.
I also forgot to say thank you for the link!
Outstanding! I agree with Ben’s comment, never the less, the work is remarkable. Kind of scary that technology has evolved to the point that it’s difficult to tell the difference between a photo of an actual organ and a CG image.
Marvelous. No words to describe his techniques. I am waiting for Michael?Ǭ¥s tutorial with screenshots! He PROMISSED in 08/08/06 to Starsoul!

almog - that’s awesome, will definitely have to post that, thanks!
Michael,
Beautiful texturing and lighting, but lousy motion on the animation. The heart actually twists quite a bit during its cycle, first counter-clockwise (looking up from the apex) during atrial systole, then clockwise during ventricular systole. Also, your model looks like it has pulmonary atresia (a narrowing of the RV outflow tract and PA).
If you are interested in contuing this kind of work, I have 13 years of experience in computer animations of the heart, I have my own company dedicated to that pursuit, and I have access to thousands of imaging studies and live video during open heart surgery. I have also used photographic sources for my 3D surface maps, though I have never achieved the specular richness that you have. Drop me a line sometime — david@blaufuss.org
David - Are you talking about the animation above? I don’t think that Michael did that, I think it was done by someone else using his heart photo. Thanks for pointing out the flaws though. I don’t think people realize the subtleties that make up a heart beat. Thanks for the info!
I have dissected a heart before
and this is not how it looks
I was able to tell it wasn’t real
quite easily
Good try though
(n_n)
(Just so you know it is far to shiny change that and it will look like a real heart)
omgg!!! that looks so REAL!!!
i must say..IMPRESSIVE!
wooooowwwww lololololoolololloololollo
sick dude lol its soo fake thought
wow very cool
S’capotte lol
thats not how u spell it George its
Je capotte
whv
