CANVAS PROJECT

September 22, 2020

CANVAS PROJECT

This was my first time using Dreamweaver to create an image out of code! I created this image by layering triangles, rectangles, circles, squares, and both quadratic and Bezier curves with varying levels of transparency and gradient.

I had a tough time with this project. I'm a perfectionist with a limited attention span; sitting for labor intensive, detail oriented projects like this one drives me up a wall, and not being able to produce the exact image in my head is extremely frustrating. There were many, many times during this process where I had to save my progress and walk away so I didn't just scrap the whole thing. Having never used any type of coding before, I am proud that I was able to produce this, but I am a little disappointed I couldn't exactly recreate my vision.

The image itself was inspired by two Cubist interpretations of Winnie the Pooh, one of my favorite characters as a child. One of my earliest childhood memories is sitting in my aunt's backyard and eating s'mores with my cousins, watching a Winnie the Pooh movie projected up on the whitewashed side of her house. When I was searching for inspiration at the beginning of the project, the image below instantly jumped out at me:

I thought it'd also be easier to complete because it is principally made out of simple shapes like triangles, squares, and circles. I was wrong; I had consistant trouble figuring out the layering, gradients, and positioning for everything. However, the background definitely gave me the most trouble out of it all, just trying to figure out how to fill a color. I eventually just went with a gradient because it was the only thing that really worked for me.

Overall, I'm happy with my finished work. Despite a lot of time, work, and frustration, I think I managed to produce a pretty good piece and learn a lot about Dreamweaver in the process.
