ZBrush anatomy study

Recommended in HD 1080p to see all the details.

After learning the basics of human skeletal anatomy, I`ve went ahead and attempted to further my understanding inside ZBrush. Trying to recreate all the bones in complete 3 dimensional space puts your mind through the next level of understanding of these shapes.

         

My aim was NOT to use reference images as image planes, rather use the methods I have learned so far to keep proportion and also look at images outside of ZBrush. I`ve done it this way to put my mind through that frustration process of trying to understand these shapes and forms on a whole new level.
Well, it was frustrating at times all right. especially when some of the references from various sources showed  confusing differences. I had to dig deeper and read up on how things worked regarding the skeletal structure.

It was a good learning experience with ZBrush as well. I wanted practice to become more comfortable with the interface and scene management. All the separate little pieces meant different subtools. In the end I`ve ended up with about 30, which had to be managed logically in order to keep a grasp on the work.

From here its on to the muscle system, first on paper. We'll see how soon I`ll be able to dwell into that area as a combination of uni work + freelance work is stealing all my free time away from me... but where's a will, there's a way :) .

Continuing with anatomy

Whilst I am working on the skeleton, university has also re-commenced. My next posts will focus mainly of the current assignment we've received, but at the moment I am going to concentrate on finishing my studies and modeling on the human skeleton.

I`ve made significant progress inside ZBrush. I`ve decided not to upload work-in-progress stuff as I will be finishing very soon, so there is no point for spoilers :) .
One thing is for sure: going ahead and sculpting the shapes and forms in 3D perspective has skyrocketed my understanding of all the different elements of the body. There were a lot of things which I could not read from my drawings. For example I could draw the basic shape of the scapula, but there were a couple of things missing from my understanding as how it fits on the body, how the head of the humerus connects to it etc.

Sculpting the skull was one of the biggest challenges. I`ve decided to re-model it several times, because I made mistakes and wanted to learn from them by recreating the model with that new knowledge. Laying down the fundamental features of the skull first, defining the main landmarks as the first step and then starting to slowly build out the whole thing from there ended up being the most rewarding approach.

I`ve took this new understanding and tried redrawing the skull in a much more detailed way. Previously I could only draw a very simple skull, but since I have a better understanding of the general planes, the little nips and tucks of it allowed me to draw something like this.

I hope you will check back soon to take a look at my final skeleton.

Drawing anatomy

Tackling an issue which you had for ages makes you so eager to see what the h*ll you were so "afraid" of before... why didn`t you try it before. These kind of thoughts were swirling inside my head just before digging myself into drawing lessons.

The lessons I`ve chosen to watch have a very good system when it comes to explaining the absolute basics of human anatomy. It is also very technical at the beginning, meaning that I`ve used formulas for everything the skeletal system is composed off. I`ve heard people saying over and over again that you need to have a loose, free approach to drawing and draw what you feel and see, but when you start at, I`ve found that technical approaches for me are better. As you progress along, these formulas will become second nature and you will realize that you didn`t even have to measure and what not, because it all comes naturally now. I`ve started understanding the fundamental rules of the proportions. I started understanding the certain areas I can experiment with, but at the same time always obey 1-2 rules so that everything looks believable.

The lessons started out with teaching me the 8-head standard formula for the human body. It went on explaining the main areas of the body and how to determine key areas like top of the skull, bottom of chin, bottom of peck muscles, naval area, crotch, knee etc. even before you actually start drawing the figure. These helpful guidelines helped me always to maintain the correct proportions of the figure. At this stage I have only used simple shapes illustrating where the rib cage will be, the pelvis, skull, legs etc.


After this I`ve moved on to investigate different parts of the body. The first element was the skull. I didn`t care how hard it was going to be, I was sure with practice and commitment I will be able to learn to draw a correct skull, but it turned out easier than expected... at least a very basic version of a skull.
The help that these formulas provide when you are at the start is amazing.. at least for me. I spent quite a lot of time before looking at people's faces, human skulls on the internet etc. but I had no system whatsoever to help me always achieve the correct proportions, planes etc.


Drawing out the skull from the front, side, back and then going ahead attempting a perspective version was quite a challenge, but it did not take a lot of time until I`ve started getting decent drawings. Thing is when you understand these basics, even if you can`t produce amazing things on a sheet of paper, inside a 3D application there is so much room for experimenting. You understand the proportions so everything will be in place and then you can mess around with the small details here and there and continue learning in your 3D package. At least this has worked out pretty good for me (stay tuned for that :) ) .

Learning the important basics of each part of the skeletal system in the end payed off, because everything started to fit together. I knew where the spine would attach to the skull, how it curved down and finally ended in the sacrum. I understood where the pelvis takes up its roll and how the legs attach to it, so the figure can stand on its legs. Examining the scapula allowed be to get a better understanding of how the back deforms because of it and also how the shoulder is built up. I had some major proportional problems around the shoulder areas before in 3D, but that is starting to go away.
Right now I have finished exploring the skeletal system.

My current goal is to go ahead and model the whole thing inside ZBrush. Now, this is going to be one heck of a challenge as it's one thing to draw something and then another to sculpt it in full perspective. This is the next stage of furthering my understanding of the skeleton and the human body in general.

Finding good reference is going to be key, because I need to see each and every bone from pretty much all the angles possible. A lot of times even those small bumps and surface details make you understand how everything works and attaches to each other.
