By introducing a true 3D display model, volumetric display technique based on visual voxel is explained. To deal with the problem of massive data generation in a 3D model, acquisition of film source based on virtual structured light is proposed. Spatial data generation of the model is implemented. Simulation results provide a support to the theory for parameter design of largescale true 3D volumetric display. Experimental results show that the described method can provide colorful, high resolution film sources for true 3D volumetric display.
