Drawing from a head bust

Without being able to see clear contours from this smooth object, I mis-proportion the first two drawings.

Practice drawing over a color background

Filed under: Real — liyiwei @ 11:06 am

This one spanned several days because I had difficulty preventing my facial hatches look like facial hairs and it was in front of the CHI and SIGGRAPH deadlines.
I plan to practice hatching from 3D sculptures (e.g., in museums) next.

The blue/cyan contours are initial layouts but they provide interesting visual effects so I leave them there.

A smiling face is a happy face

Filed under: Real — liyiwei @ 9:07 pm

When I started a drawing, I often have no idea if I will be able to finish it, and the intermediate process can look hopeless.
Just keep going and trust the eyes and the hands, and magic will happen.

There are nuances in the original (awesome) photo which I could not yet capture, so I plan to come back to this one later.

Which I started after removing a tooth and needed some activity to divert the discomfort.

Digital drawings by a kid

Filed under: Real — liyiwei @ 6:41 pm

My 6-year old niece got very interested in digital drawing after seeing me doing that.
The user interface seems intuitive enough for her to learn very quickly. She just found it weird to use the digital pen instead of her finger as an eraser.
I am observing her for informal user study (e.g. comparing physical and digital drawings for kids).

A general thought: if we want to nudge kids to do something, better to set up examples by ourselves instead of just verbal commanding.
For example, if you do not want your kids to watch TV, stop watching it yourself. And if you want them to study, sit down and read something yourself.

Quick sketches of speakers in grandpa’s centennial memorial

Filed under: Real — liyiwei @ 5:44 pm
Tags:

This is a good practice session for speed sketching. Each speaker has only a few minutes, and some finished before I could carefully observe them.

I drew the subjects into layers of the same tiff file. All hidden layers were destroyed after I accidentally rotated the file under the Windows (file) explorer, but fortunately not before I shared the layers to Instagram.

Practice drawing from a sculpture

Drawing is a very peaceful solo process, between me, the subject, and the canvas. I do not have to be concerned with anything else. Even single-authored SIGGRAPH papers need to go through peer reviews.

Time perception

I found drawing to be an excellent in-flight entertainment, especially long-haul flights that provide ample time. Aside from occasional turbulence that can shake my strokes (especially on glass tablet surfaces), drawing is pretty much immune to other distractions like engine noises and passenger commotions.
I had so much fun and focus that the plane landed before I realized.

These two drawings are from the same photo which I like a lot.
