A 3d engine at very early stage and in working progress.
The program generates randomly some rooms with some moving cubes. The camera can move with mouse (head orientation) and arrow keys (camera direction).
Needs Git Lfs Extension, Cmake (>3.1 and <3.13), TBB, OpenGL3 (>3.3) and GLew / GLM / SOIL / Glfw libraries.
On ubuntu or Debian, apt-get make most of prerequisites install
# apt-get install cmake make g++ libx11-dev libgl1-mesa-dev libglu1-mesa-dev
# apt-get install libxrandr-dev libxext-dev libglfw3-dev libsoil-dev libglm-dev
# apt-get install libglew-dev opencl-headers libtbb-dev lsb-core libconfig++-dev
On OSX, we need XCode and install some libraries with brew (SOIL must be install manually)
$ brew install cmake glm glew glfw3 tbb libconfig git-lfs
And SOIL must be install manually
git clone https://github.com/childhood/libSOIL
cd libSOIL && make
sudo mkdir -p /opt/local/include/SOIL
sudo mkdir -p /opt/local/lib
sudo cp *.h /opt/local/include/SOIL/
sudo cp libSOIL.* /opt/local/lib/In build directory, generate MakeFiles and compile project
$ git lfs install && git lfs fetch && git lfs checkout
$ cd build && cmake ../

A default setting file is present at config/nextfloor.ini.default For local config change, we can duplicate this file
$ cp config/nextfloor.ini.default config/nextfloor.ini
$ vi config/nextfloor.ini
It's also possible to change mostly setting on the fly with program parameters (See below).
Use mouse for head orientation and arrow keys for camera move. And following keys are used
- 'esc': exit
Default run, without any parameter
bin/./nextfloor # Use settings as setted in config file (config/nextfloor.ini or config/nextfloor.ini.default).
Program accept options who can override config settings
./bin/./nextfloor can be used with following options who overrides config file
-d n Debug mode, 0: no debug, 1: test debug, 2: performance debug, 3: collision debug, 4: all debug
-e n Execution Time, 0: no limit
-g n Granularity on collision computes
-h Display help
-l 1|0 Enable/Disable display config
-p serial|tbb
serial: no parallellism
tbb: uses intel tbb library
-v 1|0 Enable/Disable vsync
-w n Workers (cpu core) count (disabled if -p serial), 0: no limit, all cpu cores
For example
./bin/./nextfloor -d 0 -p tbb -v 0 # no debug, tbb parallellism, vsync off
