Vector graphics by Bryan Kilgallin

Window frost — I live in the southern part of the globe. In this hemisphere, June falls during winter. For that month, my digital media group selected the theme "frost". On 6 June 2024, I completed this piece artwork. The reference photo was obtained online. I layered tones and shapes.

Vector graphics are mathematical. They are composed of geometric fundamentals. Geometric primitives are simple shapes. Basic ones are points and straight lines.
Advanced ones are:

rectangles;
ellipses;
arcs;
polygons;
Bézier curves; and
splines.

I use Inkscape. Its file format is Scalable Vector Graphics (SVG). That can do shapes, paths, text, and styles.
Styles apply to:

fill and stroke;
object; and
layer.

Commands:

define;
locate; and
set properties.

Basic commands:

select;
move;
scale; and
rotate.

Vector graphics can illustrate cleanly. A simple image has a small file size. That is efficient for storage and transfer. Vector graphics scale without losing quality. That is ideal for printing. Which may require high quality. One file makes a card or a banner.

Here are some of my vector artworks. I exhibited the above. The images are listed chronologically. The most recent is last.

Cafe interior — I was with Urban Sketchers Canberra. It visited the Canberra Museum & Gallery. In which I found a suitable location. My equipment needs both a power source and protection from glare. So I positioned myself in the closed cafe. In which I faced the bar. I finished the above piece on 13 September, 2024.

Graffiti on the theme of deadlines — My art club was preparing for an exhibition. And its digital media group set the theme 'Deadlines'. That focused on the psychological pressure. My above conceptual artwork captures that. I completed it on 20 September 2024.

World Naked Bike Ride participant — My art group's monthly theme was 'Exhibition/Exhibitionism'. For that, I created a nude portrait. Its subject was a volunteer assistant. The event was the 2009 World Naked Bike Ride. It aimed to highlight cyclists' vulnerability.
I finished the artwork on 6 November, 2024. By request, I censored it on 12^th December 2025.

On 12 January 2025, I participated in a field excursion. That was with Urban Sketchers Canberra. The locale was Canberra City. We visited a mall called Scott's Crossing.
On 15 March 2025, I finished my above artwork. The artistic style is a collage of objects.

Technical drawing of a USB dongle and ports — The diagram above explains connecting a mouse to a smart TV.
I completed this artwork on 5 April 2025.

My digital media group had for its May theme 'May...'. I interpreted that as 'maybe'. By 10 May 2025, I created the above artwork. It depicts Schrödinger's cat.

Traced and filtered fossil leaves — My digital media group set the theme 'lasting impressions'. That made me think of fossils. So I auto-traced my photo of fossil leaves. Those were of the late Permian period, 254 million years old. Then I added a sandy backdrop. That was to evoke the natural environment. Lastly I applied a filter-effect. This enhanced the visual impact. I finished the above artwork on 8^th June 2025.

Greyscale, RGB & CMYK gradients — I was impressed by a pastel artist's presentation.
So I emulated such hues, layering gradients. These are both radial and linear. The first, radial, gradient was greyscale. For the later, linear gradients, I used colour models. I applied a red, green, and blue (RGB) gradient vertically. Then I added a horizontal gradient. That's cyan, magenta, yellow and black (CMYK).
I finished the above artwork on 16^th June 2025.
