Imgui
Dieses Projekt ist eine Immediate-Mode-GUI-Bibliothek, die für die schnelle Entwicklung von Tools und Diagnose-Schnittstellen konzipiert ist. Durch die Generierung der UI-Geometrie in jedem Frame mittels prozeduralem Code entfällt die Notwendigkeit einer persistenten Zustandssynchronisation zwischen Anwendungsdaten und der Schnittstelle. Es ist primär für die Integration in bestehende Rendering-Pipelines gedacht, wo es rohe Vertex-Buffer und Draw-Befehle erzeugt, die agnostisch gegenüber der zugrunde liegenden Grafik-API sind.
Die Bibliothek zeichnet sich durch eine stark entkoppelte Architektur aus, die komplexe, andockbare und Multi-Viewport-Layouts unterstützt. Sie verwaltet Fensterpositionen, Tab-Dragging und Node-Splitting, wodurch Entwickler Schnittstellenelemente in unabhängige Betriebssystemfenster auslagern können. Um eine konsistente Interaktion in verschiedenen Umgebungen zu gewährleisten, bildet sie native Eingabeereignisse in ein einheitliches Format ab und bietet eine robuste identifier-basierte Bereichsverwaltung, um Elementzustände über Frames hinweg zu verfolgen.
Das Framework bietet eine breite Palette an Funktionen für den Aufbau anspruchsvoller Engine-Tools und Diagnose-Dienstprogramme. Es umfasst Unterstützung für fortgeschrittene visuelle Komponenten wie Node-Editoren, 2D- und 3D-Plotter sowie spezialisierte Inspektoren, neben der Infrastruktur für DPI-Skalierung und benutzerdefiniertes Shape-Rendering. Das System ist auf hohe Portabilität ausgelegt und bietet Konfigurationsoptionen zur Kompilierzeit, die es Entwicklern ermöglichen, Kerndatenstrukturen und mathematische Typen an spezifische Engine-Anforderungen anzupassen.
Das Repository bietet umfangreiche Beispiele für die Verbindung der Bibliothek mit wichtigen Grafik-Backends und Frameworks sowie Tools zur Generierung sprachspezifischer Bindings.
