This is a rendering engine project. It includes an editor to maipulate the scene (place object, lights, ... ) It is based on C++ and OpenGL.

Requirements for compilation:

• C++
• GL
• glfw3
• assimp
• SOIL (place in external)
• freetype
• tinyxml2 (place in external)

gl-loader-file generated with https://bitbucket.org/alfonse/glloadgen/wiki/Home

Some code parts inspired by openGl 4 shading cookbook due to the fact that the subjects where studied with it.

Basic workflow for using the engine: First initialize the engine with the width and height of the screen, the subsystems to be initialized and a indication if fullscreen is intendet. The render and the IO subsystem are initialized every time because these subsystems are required for minimal functionallity.

engine.initialize("game/engine_config.xml"); or e.g. engine.initialize(1240, 720, RENDER_SUBSYSTEM , true, false);

Then create a Scene object where the objects, lights, etc. can be created from. Also the scene contains a camera and a skybox can be set for it. The scene needs to be added to the engine so that it can be rendered and update functions can be applied.

Scene * scene = new Scene(); scene->load("island-scene.xml"); engine.setScene(scene, false);

After that the basic main loop could look like this:

while(engine.running()) {
// Do your update here engine.update(); engine.render(); }

or this

engine.run();

with a callback to a update(float time_delta) function registered before.

... void update(float d) { ... } ... engine.setUpdateFunction(&update); ...

In the end the engine should be shut down to clean everything up.

engine.shutDown();

Done:

• DeferredLighting
• Shadows (Point/Spot/Directional)
  • PCF (for all light types)
  • RandomSampling ( for Directional/Spot)
• FXAA
• SSAO
• Basic Scripting
• Simple Physics(falling)
• Picking
• Objects
  • Skybox
  • AnimatedObjects (Bone-Animation)
• SceneEditor
  • Add/Delete Lights
  • Add/Delete Objects
• Scene
  • Loading/Saveing
  • Object/Light- Management

Partially done ( improvements should be done) :

• GUI

  • EditText
  • Image
  • Button

• SceneEditor

  • Add Skybox

• HDR ( basic |should be improved later )

TODO:

Structural:

• screen space culling ( material flickering when activated )
• write doc

Graphical:

• water
• bloom effect ( basic|needs major improvement)
• terrain
• OIT

GUI:

• usability improvement

Customizability:

• setting specifactions (MULTI_SAMPLES,...)
