Description
Technical Field

Background
The Head Up Display (HUD) technology refers to that light emitted by an image source is finally projected onto an imaging window (an imaging plate, a windshield, etc.) through a reflective optical design, so that a driver can directly see information such as speed per hour and navigation without lowering the head while observing the real environment outside the windshield, distraction caused by the fact that the driver looks at a dashboard or a central control screen at a low head in the driving process is avoided, driving safety coefficient is further improved, and better driving experience can be brought. When a driver drives a vehicle, the environment in which the driver is positioned is changed, so that the design of the interface displayed by the head-up display is required, i.e. the interface needs to have certain visibility in various environments as much as possible. Verification of this visibility often requires field observation by a real vehicle, which is inefficient and complex to operate.
The Unity3D is a multi-platform comprehensive game development tool developed by Unitytechnologies, which enables users to easily create interactive contents such as three-dimensional video games, building visualizations, real-time three-dimensional animations and the like, and is a comprehensive integrated professional game engine.

This technique can produce a high degree of visual realism compared to typical scanline rendering methods.
