Edit: I’m having issues getting VirtualDub to produce a video of decent quality that isn’t 800mb+ - anyone able to recommend any codecs? DivX complains if I try using that.
Description: After some reading about Additive Blending in Robert Hodgin’s tutorials (link below), I decided this would be a nice project to ‘beautify’, given the flocking behaviour tends toward little ‘nodules’ (especially once you tweek the boid rules to form little local clusters).
I added the ability to suddenly ‘repel’ boids away from a goal, rather than toward it, simply to see whether they’d maintain flock consistency as they fled. They don’t, simply because the tendency toward the goal outweighs their group behaviour so much. I intend to fiddle with that a bit.
Kinda Boring Personal Notes: Anyhow, it turned out okay, I think. I used about 3 textures and am planning on experimenting with a helluva lot more. As I’m rather new to the 3D / Texture world, well… I guess we’ll see how it goes. I have a lot of free time at the moment, being unemployed, so I want to play with some of the OpenGL stuff.
I rather rigged one of the boid rules (specifically, the tendency toward creating localised mini-flocks) for this, just to be able to see exactly what additive blending did. It was pretty fun to play with them a bit more.
