Ioquake3

Porting

Mali-400 port was done by Luc libv Verhaegen. Purpose of this port is only testing the OpenGL ES libraries, no playable experience is available yet.

Building

Remove X11 Mali-400 libraries if you installed them, install framebuffer ones! (make framebuffer in mali-libs) Current ioquake3 uses only framebuffer output, nothing else.

git clone https://github.com/libv/ioquake3
cd ioquake3
git checkout remotes/origin/mali_fb
nano Makefile.local # change DEFAULT_BASEDIR to directory where you have Quake 3 Arena game files
make ARCH=arm
cd build/release-linux-arm

Running

Run

./ioquake3.arm

in your build/release-linux-arm directory

You should get something like this:

Then enter this to run the demo benchmark:

timedemo 1
demo four

ioquake3 is not wired with any input system (game will not recognize any keyboard or mouse input), this lines will go stright to Quake 3 console that will run under the renderer output.

Benchmark results

Resolution	Frame rate	Misc.
1920x1080	4.5 fps	1260 frames 279.7 seconds 31.0/222.0/320.0/14.5 ms

TODO

Add input system (evdev?)
Add X11 support
