Key Concepts and Terminology
Scenes
A scene is a self‑contained environment that contains a collection of objects, lights, cameras, and scripts. Scenes can be nested, enabling hierarchical composition of complex environments. Each scene has a unique identifier and may be loaded or unloaded at runtime, supporting level streaming and dynamic content generation.
Objects
Objects represent visual or interactive entities within a scene. An object can be a mesh, a light source, a camera, or a container for child objects. Each object has a transform that defines its position, rotation, and scale in world space. Objects also have properties such as material, physics attributes, and scripting hooks.
Materials
Materials describe how an object’s surface interacts with light. Digiex implements a node‑based material editor that supports PBR, texture maps, normal mapping, and custom shader nodes. Material properties are stored in a JSON format that can be exported and imported between scenes and projects.
Lighting
The engine supports multiple light types, including directional, point, spot, and area lights. Lighting calculations are performed in the rendering pipeline using a combination of forward shading for primary lights and deferred shading for secondary lighting. Global illumination can be approximated with screen‑space reflections and environment maps.
Physics
Physics simulation is handled by the integrated physics module, which exposes rigid and soft body dynamics, collision shapes, and constraint systems. Physics data is synchronized with the scene graph, ensuring that visual objects accurately reflect their simulated counterparts. The engine provides an API for querying collision events and applying forces.
User Interaction
User interaction is defined through a system of event listeners and input bindings. Scripts can register callbacks for events such as key presses, controller button actions, or gaze intersections. Interaction models can range from simple button presses to complex gesture recognition, with the ability to combine multiple modalities.
Data Flow
The runtime engine orchestrates a pipeline that processes input, updates scripts, advances physics, and renders frames. The engine operates on a fixed time step for physics updates and variable time steps for rendering, ensuring deterministic simulation while maintaining smooth visual output. Data synchronization across threads is managed through lock‑free queues to minimize latency.
