Abstract: By introducing a true 3D display model, volumetric display technique based on visual voxel was explained. To solve the low-resolution problem of true 3D LED displayer, multi-machine synchronization projection method was proposed. With serial section images of true 3D display, the codec algorithm for true 3D display was studied and geometric correction model based on ray tracing method was built. The experiment proves that this method can build a practical and high-resolution true 3D displayer and can display the object exactly.

Key words: true 3D, visual voxel, ray tracing, geometric correction
