Inspired by the work of Andy Gilmore, specifically work for the new Africa Hitech album on Warp records, (available on Bleep), I was intrigued to be able to create a means of creating triangulated images in Flash.
The Flash version we created uses a square movie clip subdivided into 4 triangles. In the first iteration, the movie sets the colour of each triangle randomly from a list of predetermined colours. This creates a very random image. It might be more expressive to tend towards using the colour of the triangles around to determine the color, with a chance of using a random color.
In the second iteration, it uses a bitmap as the generator of the colors. It loads a bitmap image, and then overlays the grid of squares.
Then for each triangle within the square, it uses getPixel to get the colour value in the middle of each triangle. This creates an intriguing triangulated pixel aesthetic.
Try it here:
Further experiments allow us to change the size of the movie clip, creating greater or lesser detail, and creating alternative triangular forms within each square.
