Heat Signature gets pretty with "infinitely scaling vapor layers"

Andy Chalk Dec 24, 2015

Heat Signature, the space-borne stealth game-slash-carjacking sim being developed by Gunpointcreator and former PC Gamer editor Tom Francis, isn't really the sort of game that screams "luscious eye candy within." But the recent implementation of "infinitely scaling vapor layers" has it looking a lot prettier than you might expect.

The problem, as Francis explained on his blog, is that when the camera automatically zooms out to maintain a view on multiple on-screen objects, "the star layer tiles very obviously and soon the vapor layers stop showing and it’s all a big blur." The solution? Let the layer detect when it's using too many tiles, then create a new, larger-scale layer, fade it in, and destroy the old layer once it's fully faded out.

The process is probably more technical than that, but the important thing is that it looks good and Francis is happy. "It works! I love it," he wrote. "Feels like a real victory of code and art: we had this big scary problem, a gap in what we could do to a good standard, and we dodged around it for a while, and then [artist John Roberts'] perfectly tiling dust layer and my new autozoom system came together in a way that suggested a smarter approach, and it just solves it completely."

Francis released a "better" video of the infinitely scaling vapor layers here, but I prefer the one above: It's slower, it's got a little bit of a soundtrack going on, and it zooms both ways, which I think showcases the feature more effectively. And not only does the new system look great, it will also allow him to use the autozoom function more liberally. "Turns out that once those zoom levels look good, there are a few gameplay uses for them!" he added.

Heat Signature is still in alpha testing, which you can sign up to take part in at heatsig.com. The scheduled release date is, officially, "no idea."
