View Full Version : Need ACCURATE anatomical modeling

I could possibly use some help modeling in the future when I do some more work for biomedical clients. I've been working with major medical clients for a number of years now.

Below is a heart model I purchased and use. It is quite accurate. And the mesh is so clean and nice. I could possibly have need in the future of someone who could model anatomy like this from reference drawings (not front/top/right photographs).

I imagine it is difficult to find a person gifted enough to be able to do this level of organic, anatomically accurate modeling.

Where would I find someone of this ability?

What are some of the best commercial tutorials to learn to do this kind of clean, accurate modeling? I am excellent at surfacing and lighting and post production. But modeling is not my strength yet.

Also, if I can ask the experts here, what is the technique used to go from fewer polygons to denser polys without creating N-gons. I see it used in many places on this model. What steps and tool is used in Lightwave for this?

this may have been modelled from a point cloud or from cross sections produced from a CAT or MRI.

Not volunteering but you may want to find someone who uses this

In LightWave, you can use a few methods. There is no "Step Down" button but you can use Add Edges with merge and delete polys etc. It is just a process of constant refinement. It is harder to do exact models from box modeling. But you can block things out this way and then switch to a process of modeling by adding edges and so on.

A very viable method is to start with a scan or CAD file and then retopo it. That would work well for medical purposes. Also using a sculpt prgram and then repopoing that is another way to go.

Here are is an example of a model I retopoed over an extremely dense CAD file.

speismonqui,

Thanks! That's a great find!

There are some really gifted modelers on this forum. I'm pretty good, but I don't think gifted. I think the greater difficulty would really be who's been studying modeling AND anatomy, not cars and spaceships, PEW PEW!

That model looks like you bought it off TurboSquid, that is actually an good place to find pre made medical models. They also have a "custom order" option where they will have models made to your specs.

Of course if you can find someone here to do it all the better. Just understand that cost for pre-made will likely be a lot less than custom made.

You have to remember people now has more tools to model/sculpt thanks to programs like Zbrush and 3dcoat.

Agreed, although the modeller could also sell the model online and could possibly agree a slightly reduced cost based on that.
