In order to achieve a clear and steady swept-volume display, the method of swept-volume display based on cylindrical space projection was presented. One projector generated the image volume in π×70 mm×70 mm×150 mm space. Experimentally, the resolution of images was 800 pixel×600 pixel×360 pixel, which resulted in almost 345 million voxels. In order to achieve space voxels with uniform brightness, curved reflectors were also designed. In addition, the match conditions between triangles and the scanning planes in the volume space were classified and a swept-volume graphics engine based on embedded platform was designed. The image rendering the hardware foundation for three-dimensional (3D) dynamic images generation was achieved. Demonstrated in the experiments, light source utilization of the second-generation system based on curved mirror is about three times brighter than the first-generation 3D minitor based on flat mirror, and this system is able to display color, clear and well-proportioned 3D images in brighter room light.
