"Terminal Velocity", a better Linux terminal graphics demo

Last week i released a simple graphics demo for the Linux terminal (Fun with terminal color).

The low framerate and the mostly static graphics bothered me a bit. So, i , uhm did it yet again. Another demo, this time using Inline::CPP and massaged versions of tinyraytracer and tinyraycaster to provide some actual graphical content. As a matter of fact, Inline::CPP didn't work for my borrowed(*) code, and my understanding of CPP is a 20 years out of date. So i override the Inline::CPP RecDescent module to ignore my bugs. Hey, it's not production code, just a demo...

As in the last demo, your Terminal needs to support full RGB colors and have a size of at least 270x60 in size (characters, not pixels). SDL is sort-of-optional this time; the demo will run without sound if it can't load SDL. And as said above, you'll need to install Inline::CPP as well.

Here's the mercurial repository: https://cavac.at/public/mercurial/demos/terminalvelocity/

And the YouTube video: https://www.youtube.com/watch?v=MWcuI2SXA-A. OBS and YT compression did munge the quality a bit, though. Probably my fault for not understanding the OBS settings...

    Very neat! If Inline::CPP has bugs, please report them on GitHub. And looking at the code, it seems like this should "really" use (or could benefit greatly from using) Inline::Pdlpp?

    Missed the first time around but . . . Thatís pretty impressive.

    The cake is a lie.

      Thanks :-)

      I've since learned a bit more on how to use Inline::CPP and i've got a two week vacation coming up. There may be another, better demo coming, but i can't promise anything.

    Thank you cavac for the cool demonstration and music.

      Well, the music isn't mine (see YT comment section for details) and i only imported some existing graphical demos and adapted them to use my imagecat routines.

      Plus doing a lot of fiddling with the timing to make it work with the music. Ye olde SDL library didn't allow me to skip the parts properly i've already timed, so i resorted to using the stopwatch function of my wristwatch and the old pen&paper method of calculating the correct lengths for all the different parts. Talk about old school ;-)

    And I just finally watched the actual video: that is far beyond neat! Thank you for the shout-out, and especially for the nostalgia trip back to the late 80s with Amiga demos and suchlike.
