Any chance that RVGL will be ported to Raspberry Pi?

Thanks.

I thought somebody was about to do that since last January

Well yes, RVGL has been compiled successfully on ODROID before, so a generic ARM build for RPi, etc. is also possible. In fact, if I'm not mistaken, the ODROID build should already work on any armhf architecture.
Here's the rvgl-odroid release page: http://forum.odroid.com/viewtopic.php?f=91&t=20689
Direct link to where the package is hosted: rvgl-odroid (requires libgl-odroid)

Perhaps you can try it and let us know.

I have tried the latest ODROID build on my Raspberry Pi 3. Sadly, it doesn't work correctly. The in-game menu works without any issues, but the actual gameplay has graphical glitches that make the game unplayable. According to the game log, there is a lot of missing OpenGL extensions.

Are you also having a libGL error popup: Could not create GL context? That's what I have with my Pi right now. I installed both things (rvgl-odroid and libgl-odroid). The terminal says: LIBGL: Unable to create EGL display. http://pastebin.com/jbBDzrr9

I can't get the game to the frontend either way.
Any idea? I'd love to create a re-volt handheld and this is a good step in the right direction.

try asking in the odroid forums

It looks like you don't have a proper 3D acceleration enabled on your Pi. (Can be enabled in raspi-config under Advanced Options -> GL Driver.)

I will soon have a Pi to play Dreamcast online (DreamPi), really curious to see how rvgl runs on it, will report back.

The missing extensions are harmless as RVGL doesn't need/use any of those. From the screenshot you posted, it appears that the previous frame is not cleared before a new frame is rendered. Can you try a track that doesn't use a skybox, like Garden or Museum? Also post the re-volt.log file generated by the actual game - you can find it in the game's "profile" folder.

@r6te: in your case it could be as linuxguru said, so try following his advice:

Hi Huki!

I got the game working. It runs quite OK, lowest settings it runs on 20-60fps on 640x350 with several drops, mainly cars affecting them. I cannot get a lower resolution than 640x350 though - is 480x320 possible at all? I hope so!

This pastebin is the re-volt.log file after opening Toys in the Hood 1 and closing the game. The skybox seems to be the issue indeed. How to fix this? Thanks!

Perhaps you know some other ways to improve performance. I allocated 128mb memory to the Pi, turned on GL via raspi-config.

Thanks still! I'm planning to create a handheld with multiplayer possibilities, but I prefer improving the performance first before starting.

P.S: the ball bearing is bugged, doesn't seem to reflect at all and looks weird.

I've been able to get RVGL running on my Raspberry Pi2 using the provided advice from linuxguru and some additional help from r6te. I happen to have a capture card, so i went and shot some footage of the game running in 720x480.

Video 2

I'll be more than happy to provide more footage and/or logs if need be.

PS. Don't mind the audio, my capture card doesn't handle HDMI audio very well when capturing it directly through OBS.

EDIT: I've managed to use the fake KMS in order to get cropping to work, and have managed to run RVGL at 528x332 ( an arbitrary resolution).

Toy World 528x332 near 60fps lock

Very nice to see some working results.

RVGL doesn't limit the resolution, so I guess it depends on the card / configuration. But Odie seems to have achieved arbitrary resolutions already.

Thanks for confirming, I'll fix that in RVGL and ask the ODROID maintainer to update it, so you'll have to wait till then.

Not sure, have you tried disabling reflections?
