For low cost MCUs without hardware accelerators, all the rendering are done using the highly optimized software ported for target MCU. Hand help panels, limited consoles can be realized using this variant.
Modern MCUs such as the Renesas RH850, NXP iMx RT, Cypress Traveo have inbuilt GPUs that supports hardware based rendering to create 2.5D effects. Automotive Cluster, Industrial HMIs can be built with such platforms.
Sparklet runtime leverages OpenGL to render 3D graphics on higher end processors typically running Linux OS. This enables advanced effects and high performance to implement Digital Twinning, AR/VR terminals etc.
