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
