Functional Focus: Native UI Development, Custom Graphics Rendering, and Application Tooling • High-Density 3D Rendering: Author custom shaders, instanced geometry buffers, and batching algorithms to render large numbers of objects at high frame rates in a single draw call. • Interactive Visualization: Build 3D interactive scenes with camera controls, running on rendering timers decoupled from the underlying simulation clock. • Backend Connectivity: Consume a backend API from the client — REST calls for request/response operations and an async client for long-lived, server-pushed updates — without blocking the UI event loop. • Client Security & Packaging: Integrate UI event loops with backend state, enforce dynamic role-based UI visibility, and build installer packages with runtime-configurable server endpoints. Requirements Mandatory: • C++ • Native GUI toolkit (e.g. Qt) with signal/slot or equivalent event model • OpenGL, shader programming (GLSL), instanced rendering, batching • Camera controls (e.g. arcball), scene graph management • REST client integration, async client for streaming/server-push updates • Role-based UI visibility, endpoint/config management • Installer/packaging tooling for the target OS(es) Optional: • Python (for a Python-based UI framework binding) • QML, cross-platform UI frameworks • Vulkan, GPU profiling tools • Geodetic/3D coordinate systems, large-scene LOD techniques • WebSockets, connection retry/reconnect strategies • Certificate pinning, secure credential storage • Auto-update mechanisms, code signing
