Tweaks to transparency, blurred edges and density.

The above image shows the results of some code tweaking. I added random transparency to layers (inspired by Paul Reed) and decreased the range of blur. The result is a little more variety of colour and a greater likelihood of hard edge.

Above is a selection of some explorations of chevrons after Noland and Mehring. I had to add an additional parameter for the angle of the chevrons; for the final implementation I’ll need to make sure all the rendering methods use the same number of parameters. There is also the issue of weighting; the parameters for each layer (stripe) are all equal, but the rendering method (and background colour) have a disproportionate effect on the final composition. This means I may need (if using an MLP) to repeat the number of parameters that represent render method and background colour to increase their weight. Following is a detail of one of the chevrons… (more…)

In the Key of Blue II, Howard Mehring, 1965

Mehring certainly enforces my interest in the sine-wave method of generating compositional elements (due to his emphasis on rhythm, musicality and repetition). His inverted ‘T’ compositions (like the one above) emphasize a central axis of symmetry and his work with chevrons encourages me to investigate chevrons.

Softer Gradients and Moiré Patterns

I forgot that I had already written code to increase the amount of blur in a shader (written for my early grant applications years ago); I just had not tried to use very large blur amounts since I had not looked at that shader code! In the images above, the max blur is the whole width of the display (1920) so very soft and subtle gradients are possible. To emphasize this increased blur, I used only two layers on top of the background. The following image shows one of these subtle variations at full size. (more…)
