TinyWorld

This is a work in progress which purpose is for me to learn C++.

Todo:

• make entities learn to look for food
• make entities move randomly and die after some time
• continus formated statistics
• terrain height
• controled camera
• normal mapping
• physically based shading
• gamma correction
• deferred shading
• robust shadow volume
• batched rendering
• ambiant, diffuse, specular lighting
• png textures
• obj, mtl parser
• vertex array object
• basic entity component system

Requirements

• GLFW 3.1.1 + (website)
• GLM 0.9.6 + (website)
• Ninja 1.6.0 + (website)
• Tup 0.1.2 + (website)

Basic usage

Type make and the application should configure, compile and run \o/.

Optionaly, you can run:

• make configure - generate the project
• make compile - compile the application
• make test - compile and run the tests
• make run - run the application
• make tidy - run cland tidy static analyzer
• make check - run cppcheck static analyzer

Setup

Mac OSX

brew update
brew tap homebrew/versions
brew install glfw3 glm ninja
pip install buildfox

Ubuntu

Prerequisits:

apt-get update
apt-get install curl unzip python-pip cmake

Libs:

apt-get install libc++-dev libglew-dev

Build system:

apt-get install ninja-build
pip install buildfox

GLM:

curl -LO http://downloads.sourceforge.net/project/ogl-math/glm-0.9.6.3/glm-0.9.6.3.zip
unzip -q glm-0.9.6.3.zip
sudo cp -r glm/glm /usr/include/
rm -rf glm glm-0.9.6.3.zip

GLFW3:

curl -LO https://github.com/glfw/glfw/releases/download/3.1.1/glfw-3.1.1.zip
unzip -q glfw-3.1.1.zip
cd glfw-3.1.1
cmake .
make
sudo make install
cd ..
rm glfw-3.1.1.zip

Static Analyzers

To install CPPCheck:

git clone git clone git://github.com/danmar/cppcheck.git
cd cppcheck
cmake .
make && make install

To install Clang Static Analyzer, llvm-cov, clang-tidy:

brew install lcov
brew install llvm --with-clang
export PATH="$PATH:/usr/local/opt/llvm/bin/"

or:

apt-get install llvm lcov

Generate irradiance map

You need to install rlk's envtools, util3d, and sht.

git clone git@github.com:rlk/util3d.git
git clone git@github.com:rlk/sht.git
git clone git@github.com:rlk/envtools.git
cd sht && make && cd ..
cd envtools && make && cd ..
sudo cp sht/shtrans /usr/lib/
sudo cp envtools/envremap /usr/lib/

You also need to install ImageMagick. If you'are on mac you can type brew install imagemagick.

Then simply place your cubemap's png images in the resource's environement folder (named front.png, back.png, left.png, right.png, top.png, bottom.png) and run ./scripts/cubemap2irrmap.sh -i lib/res/textures/environments/stormyday.
