How to Learn the Muscles of the Body for Artists - Part 3 - Locating the Pelvis From the Back
Diary of an Aspiring Board Game Artist - Part 6
If you joined in with last week's instalment and tried to draw the pelvis accurately from the front, you'll know how painful that process was. Well, let me reassure you and tell you that you've reached the crest of the hill and things get easier from here on in.
Let's just remind ourselves why we're doing this tortuous process. As an artist, learning anatomy is desirable. So we need to learn the muscles and where they start from and finish. To do this for the leg muscles we need to know where they connect to the pelvis. And for this to be helpful, we need to know exactly where the pelvis is.
What you've already learnt will stand you in good stead for this instalment. There are lots of similarities between the pelvis seen from the front and the back. Apologies for the rest of the post entirely consisting of pictures of a fella's backside. It's all I've been looking at all week, so some sympathy would be nice. Anyway, let's get started.
Draw the exact same grid as last week. The only difference is learning where the two starting marks go and the initial horizontal line. The rest is identical.
2. The top of the pelvis here is exactly the same as last week. Excellent.
3. This line is slightly different. Notice how it continues further on that last week's. Look carefully at where it crosses the guidelines and where it finishes.
4. These lines coming from the top of the pelvis are very similar, they just continue down to that 2nd gridline.
5. The gradient of these two lines gets a little steeper and finishes just past halfway down between the two gridlines.
6. Draw two curves that finish up pointing downwards.
7. This horizontal line is at the same level as the one from last time.
8. Now add two "cat ears" to the top of this line and erase the parts of the original horizontal line that are not needed.
9. Now draw two more curves that finish on the 4th gridline pointing vertically downwards.
10. The bottom line of this section is the same again as last time. Phew.
11. Add in these two little marks. They create junctions with three spokes.
12. This again is very similar to last week's. It's just that you can see every part. Notice the final tiny rectangle sits just below the 5th gridline.
13. From the tiny marks drawn in step 11, draw two curves. Notice where they intersect with the gridlines and where they finish.
14. Draw on the 8 circles.
15. Back to the sides of the pelvis. Draw short lines parallel to the slanted guidelines. They finish just above the 4th horizontal gridline.
16. Draw two more short lines that create a small triangle with the gridlines.
17. Draw a shallow curve approximately parallel to the diagonal guideline. Notice where they finish.
18. Make two tiny horizontal marks from the ends of the previous lines.
19. These two lines are the same as last week's.
20. This part is the same again as last time.
21. As are these lines.
22. Draw two short vertical lines on the central gridlines.
23. This part is the same as last time also. See, all of that hard work finally pays off.
24. Add in these four lines that come from the vertical lines in step 22. And that's it!
25. Let's check it against the skeleton.
Not too bad even I do say so myself. this took a lot less time to get right that the front of the pelvis. Which is nice.
Next time, we'll look at the side view. After that, we'll see the differences in the female pelvis. Bear in mind that the pelvis is by far the hardest part of the skeleton to visualise. This pelvic knowledge will help us immeasurably when it comes to locating the muscles. We'll be able to draw the origin points of the muscles on to the pelvis and by extension on to the skin.
Happy pelvis drawing and I'll see you next time.
