Cybermals-Engine

A lightweight high-performance game engine and application framework.

Features

CybObjects

• reference-counted objects
  • optional thread-safety
• linked lists
  • optional thread-safety
  • supports insert, remove, and get
  • supports arbitrary element size
• vector collections
  • optional thread-safety
  • supports insert, remove, and get
  • supports arbitrary element size
• queues
  • optional thread-safety
  • supports enqueue, dequeue, is_full, and is_empty
  • supports arbitrary element size

CybUI

• depends on CybObjects
• grid-based widgets
  • grid
  • label
  • button
    • supports both push and toggle modes
  • text box
    • supports both multi-line and read-only modes
    • supports variable-width fonts
    • supports caret placement via clicking
    • supports insertion and removal of both text and entire lines
    • does not currently support selection of blocks of text
    • does not currently support cut/copy/paste
  • list box
    • supports both single and multi-select modes
  • progress bar
    • supports max and current values
  • supports creation of custom widgets
• UI event subsystem
  • translates normal SDL2 events into UI events as needed (ex. SDL_MOUSEMOTION -> CYB_UI_MOUSEMOTION)
  • translated events indicate what widget received the event
• cached resource management
  • textures
  • fonts
• XML UI definition files
  • build simple to complex user interfaces with a single self-contained UI definition file
  • UI definitions can also be stored as strings within your app or loaded from any source supported by the SDL_RWops structure

CybMath

• 2D, 3D, and 4D vectors
  • supports addition, subtraction, multiplication, and division
• 4 x 4 matrices
  • supports identity, translation, rotation, scaling, and projection matrix generation
  • supports multiplication
• quaternions
  • supports creation of a quaternion from an axis and angle
  • supports quaternion multiplication
  • supports converting a quaternion to a 4 x 4 matrix
• axis-aligned bounding boxes
  • supports collision detection with points and other boxes
  • supports generation of a box from geometry data
  • supports generation of geometry data from a box
  • supports rotation
• sphere bounding volumes
  • supports collision detection with points and other spheres

CybRender

• manages one or more OpenGL contexts
• supports OpenGL 2.0+ and OpenGL ES 2.0+
• supports OpenGL ES 2.0 and 3.0 on Windows via ANGLE
• uses resource caching to prevent repeated loading of the same resource
• shaders
  • shader code for a single program is stored in a single self-contained file
  • supports vertex shaders
  • supports fragment shaders
  • supports geometry shaders
  • provides functions to easily attach matrices and textures as shader inputs
• meshes
  • uses vertex buffers
  • uses element buffers
  • uses vertex array objects
• cameras
  • supports relative and absolute movement
  • supports Euler angle rotation
• textures
  • supports PNG and JPEG image loading
  • multiple textures can be used with separate texture units
• lights
  • supports one or more light sources
  • supports the common light attribs: position, ambient, diffuse, and specular
• materials
  • supports the common material attribs: ambient, diffuse, specular, and shininess
• armatures
  • uses GPU skinning for optimum performance
• animations
  • supports location, rotation, and scale keys
• asset management
  • supports saving and loading of meshes, textures, materials, and armatures
  • assets can be stored in a single compact file with optional encryption

Supported Platforms

• Windows
• Linux
• Android
