Awesome

Highlights

• Create, save and load scenes.
• Create GameObjects and modify their behaviours using Component system.
• Explore the scene using a Unity-like camera.
• Configure different engine properties: renderer, time management, ...

Installation

• Download the last release (or whatever release you want) from the Releases section.
• Extract Build.zip.
• Execute LittleOrionEngine.exe.

Usage

Please refer to our Wiki in order to learn how to use the engine.

Release History

• [1.0.1] Erradicating the bugs and polishing
  • Lots of bug fixes.
  • Tuned up controls in order to give best user experience.
  • Performance improvements when loading resources.
• [1.0.0] v1.0.0 release is here!
  • Mesh materials. It mesh has its own material, that stores different textures and light parameters.
  • New ComponentLight, that represents a light source for the scene. It's used along the mesh materials.
  • Mouse picking. Game objects can be selected clicking on them in scene window.
  • Gizmos. They are used to modify the transform of the selected object.
• [0.2.2] Binary files and scene serialization
  • Better resources management.
  • Assets are transformed to less space-consuming format.
  • New cache that avoids duplication of resources.
  • Serialization of a scene, that allows loading and saving scenes.
• [0.2.1] Speeding up the engine!
  • New module ModuleCamera. It contains camera frustums that can be attached to GameObjects.
  • Two new tabs, Scene and Game. The former contains the scene seen from the editor camera while the later contains the scene seen from the game camera.
  • Frustum culling. With this improvement meshes that are outside camera frustum are discarded in the render process.
  • Camera clear modes. Camera can be cleared into a skybox or a plain color.
  • Texture is rendered using a texture instead of OpenGL primitives.
  • Quadtree and OctTree. With this improvement we can speed up even more the render process by reducing the number of checks.
  • New module ModuleDebug. It contains usefull Debug functions.
• [0.2.0] And there were GameObjects
  • GameObjects come in. Each GameObject represents an entity that can be modified using components.
  • Components are objects that contain different entities parts, like meshes, materials, etc.
  • New hierarchy window that represents the scene GameObject hierarchy.
  • Revamped properties window. Here component parameters can be modified.
• [0.1.5] Final 0.1 version (this is the one teachers)!
  • Fixed various bugs.
  • Several refactors in order to follow good C++ practises.
  • Super cool README.
• [0.1.4] New LOG, preparations for final 0.1 alpha version!
  • Revamped log. It displays messages in a clearer and more readable way.
  • Debug messages are captured from Assimp and OpenGL.
  • Filter messages by soruce!
  • Model texture can be overwritten dragging and dropping a png file into the engine window.
• [0.1.3] wow UI, so much configuration options
  • New gorgeous GUI.
  • Lots of new configuration options for different modules (camera, render, ...).
  • Scene is rendered in a separate window.
  • Model properties are shown in a new window.
  • Camera speed and focus is calculated regarding the loaded model size.
• [0.1.2] Time starts to flow, impending new GUI shows in the horizon...
  • Added time module, that controls time flow. It implements two clocks, the real time clock and the game clock.
  • Time can be paused and stepped foward one frame. Also time scale can be changed.
  • FPS can be limited.
  • Started new implementation of GUI. Added some new info to camera config.
• [0.1.1] This is about model loading and a camera
  • Improved model loading. Is possible to load models dragging and dropping their .fbx files into the engine's window. Camera will be scaled accordingly to new model dimensions.
  • Improved camera controls. Pressing F will focus the camera on the loaded model. Also, pressing Alt will make the camera orbit around the current model.
  • Added bounding box. Pressing B will enable/disable the bounding box of the current model.
• [0.1.0] Here comes the base version!
  • It can load models from fbx files using a diffuse texture.
  • Camera can be controlled in Unity-like style.
  • Engine has basic UI with several config and debug options.
