RealEngine

Basic engine created for UPC's Master in Advanced Programming for AAA Videogames.

Features

• 3D Scene view with Unity-like controls
• Loading basic 3D models into the scene by dragging and dropping files
• Basic console log
• Basic configuration and properties panels

Additional features

• Basic templated pool data structure to allow for faster allocation/deallocation of resources
• Rendering to framebuffers to show the scene inside an ImGui window.

How to use

Loading models and textures

• Drag model files inside any engine window to load it and replace the current geometry
• You can also load a different texture file for the model in the same manner

Menu items

• File
  • Quit: Exit the engine
• View
  • Open/Close different panels from here
• Help
  • Documentation: Go to wiki page in github
  • Download latest: Go to releases page in github
  • Report a bug: Go to issues page in github
  • About: Open/Close about panel

Scene view navigation

Left click to focus on the scene window first.

• Right-click to enter flythrough mode
  • WASD + QE to move around
  • Mouse to look around
• Alt + Left-click to orbit around the camera focus
• Alt + Right-click to zoom with the mouse (moves the camera focus)
• Mouse wheel to zoom (moves the camera focus)
• Arrow keys to move around
• F key to focus around the geometry
• Shift to move faster (5x)

Movement and zoom speed depend on the distance to the focus point (zooming out makes moving and zooming faster).

Configuration panel

  • Application name and organization
  • FPS and MS graph
  • Change Framerate Limit
  • Activate/Deactivate Framerate Limit
  • Activate/Deactivate VSync
• Hardware
  • Information about library versions
  • Information about CPU, RAM and GPU
• Window
  • Change window mode
    • Windowed
    • Borderless
    • Fullscreen (Not working properly)
    • Desktop Fullscreen
  • Change brightness
  • Resize window
• Camera
  • Frustum vector information (read-only)
  • Change camera position
  • Change camera movement/rotation/zoom speed
  • Change the shift key speed multiplier
  • Change near/far planes
  • Change the vertical FOV
  • Change the background color
• Textures
  • Change min/mag filters (applies to all textures)
  • Change texture wrapping (applies to all textures)
  • Information about loaded textures (size and preview)
• Models

    • Meshes (vertices, triangles and material)
    • Materials (texture information)
    • Information about the calculated bounding sphere

Properties panel

Contains information about the currently loaded model

• Geometry (meshes and bounding sphere)
• Textures (size and preview)

Console panel

Prints all logged information and allows you to input commands.

There are no commands currently available.
