Kulture Savers

Blur Cluster

Developed from the pre-RiscPC Flame Cluster effect, Blur Cluster uses a mix of dot rotation and horizontal blurring for a relaxed and yet quite animated saver effect. The colour range is enhanced by blurring the separate RGB elements at different rates, and by altering the dot plot colours depending on their xyz coordinates. Effect is 100% ARM assembler.

Shade Cluster

A revision of the old flame cluster effect on which the processor intensive Blur Cluster effect is based. Shade Cluster uses a little 3D rotation routine and a tasty random generation routine to create a kind of squirming, growing virus that mutates around the screen. Or something like that.

You can alter the growth rate, the rotation speeds, the res, and optionally have trails.

Spray

One of the Paul Wheatleyal screen saver effects that I wrote on an ARM2 machine, years back. The effect has been constantly upgraded as I got my hands on new machines, and now runs in 1024x768 with a tasty 256 colour redefined palette. The effect has featured in a variety of Quantum and then Kulture demos in the past, and its very laid back and ambient look makes it ideal as a screen saver effect.

Star

Another blur effect, this time using sine driven sprites to create a swirly star kind of effect. Reasonably laid back and the title image and gradual fading in and out of the sprite plotting rounds it off nicely.

Haze

Very simple code but serious design is the explanation behind this effect's heavy use of BASIC. Probably the most laid back effect of the bunch, Haze steadily builds a picture on the screen by plotting rows of 45 degree shaded lines in 24bit colour. The effect runs for around ten minutes (depending on screen rez and processor speed) before screen clearing and starting again. An essential effect for users who find the more animated effects too distracting.

Substance

Based on the Star effect in technical terms, Substance uses exactly the same graphical effects - transparent sprite plotting and screen blurring (although this time it's a fixed RGB blur). The difference is a whole load of work put into the design of how these effects are used. Spinning shapes and the subtle combining colours are used to produce five different Substance types (as usual, all with pretentious names), including Visionary, Raw, Kinetic, Globular and Smooth.

"Yeah man, I can see the music coming out of the screen... and it's all kinda... multi coloured streams of light. Groovy."

Vortex

Vortex is a re-working of that old circles trick - plot a couple of sprites worth of circles over each other in some kind of warpingly transparent way, wibble them around a bit, and Paul's your uncle. This time, the circles idea has been combined with some blurring to give it a spacey look. The blur code was specially modified so that the blue element appears trailed and the red colour is hardly trailed at all. The code is almost identical to that used for the Substance effect. All the development time went into making the effect look good from a design point of view - work that's much more important than the actual technical coding.
