Confessions of a researchaholic

Practice drawing a kitchen counter

I sat across the counter and panned + tiled my head around for sighting.
The fruits, with irregular shapes, tolerate more mistakes than the more regular cooking coils.
I was not sure how to draw the mesh bag containing several beets, so I lightly touched the grid structures first followed by heavier contours.

Practice drawing ellipses with a kitchen counter

Daichi commented that this one is orthographic but not perspective projection.
I have had difficulty with weak perspectives like this one, so it can help to place vanishing points far outside the canvas.
Tools like Adobe Sketch can help with placing vanishing points and lines, but I can also practice this without assisting tools, either digital or analog like rulers.

Commonalities between research and drawing

Both require sighting novel and interesting ideas or scenes. Without this important first step, the rest will fail even with perfect execution.

The author needs to be patient and persevering to complete a sufficiently challenging work without ever giving up.

Strong objectivity is required to help us see the reality without being blinded or obscured by our biases and wishes.

Drawing is one of the few activities, aside from SIGGAPH deadline, which can enter me into the zone.

Practice sighting scattered books and other objects on a low table

Filed under: Real — liyiwei @ 10:48 pm

I drew this low table top as it was without any clean up or modification; the inherent disorder and complexity took me more than an hour to complete this exercise.

I did not notice the streaks caused by the texts on the back page slipping through until photographing the canvas.

Drawing feet on a low table

Filed under: Real — liyiwei @ 6:19 pm
Tags:

The feet are the main focus of this drawing, looking better while taking me much less time to draw (at most 3 to 5 minutes among the roughly 1 hour session) than the cluttered desktop.

Clear sighting brings out clarity and reduces unnecessary manual works.

Practice drawing an unoccupied office floor

Filed under: Real — liyiwei @ 5:18 pm
Tags:

I picked this sharp corner, which looks fascinating, from the office floor that we just moved away from to practice extreme perspective. I panned my head around, so my drawing is more of a cylindrical perspective projection. This panning probably also caused my mistake of not putting the two vanishing points at the same horizontal line.

Practice sighting a room corner

I did not find mechanical sighting measurements very helpful or enjoyable, so instead I just place rough outlines on the canvas, see if they look right, and adjust.

Practice sighting a doorway

Filed under: Real — liyiwei @ 10:27 am

Drawing from a real scene is more challenging than drawing from a photograph, due to the need to carefully sight the relationships on a virtual 2D plane without wandering around in 3D.

The instruction book says 30 minutes but this one took me almost 2 hours because I had difficulty measuring the perspectives and proportions entirely by sight and eventually had to place down the horizontal vanishing point first.

After van Goth

I bought these sketch books before 2006, did not start to practice until 2015, stopped around 2016 to pursue my own path, and resumed reading today.

Copying from a master can be quite fun and help me appreciate their greatness.

Practice drawing a smiling child

Filed under: Real — liyiwei @ 4:29 pm

Slight deviations of proportions can dramatically change the facial identity. In this case, I drew the eyes slightly too large and too high above the nose. The kid looks even more exciting than I could capture. I can denser the hairs further but decided not to bother with extra manual labor.

Loose drawing

Filed under: Real — liyiwei @ 11:39 am
Tags:

Some people draw better when their brains are in a looser state; for me, it still requires great focus, no less than coding or writing research papers.

I was quite sleepy so I did this one freestyle without much structuring; the effect is completely unrealistic but yet kind of fun.
