Abstract: In response to the demand for simulation effects consistent with real hardware, a smooth transition method is proposed to enhance the imaging effects of the entire simulation system. By analyzing visual persistence effects and system imaging delays, a two-point third-order Hermite interpolation is used to handle smooth transition time and imaging color respectively. Through comparative experiments, the results demonstrate that this method can adaptively smooth the imaging of the entire simulation system, thereby having solved issues such as real-time dynamic imaging flicker and instability. The significance of this method lies in enhancing the imaging quality of the virtual 3D simulation experimental system for embedded microcontrollers, improving the visual effects of embedded microcontroller 3D simulation, and mitigating the impact of problems such as abrupt changes and artifacts. The significant application value of a virtual 3D simulation experimental system for embedded microcontrollers in the fields of education and design is presented.
