Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two-dimensional displays are used for three-dimensional imaging via binocular disparity, then depth perception is achieved, but vergence-accommodation conflict occurs and eye fatigue increases
Solution Approach 1:
The patent transitions from two-dimensional display to three-dimensional volumetric display by adding the depth dimension. Instead of simulating 3D on a 2D surface, the system creates actual volumetric images in three-dimensional space using multiple projected planes, allowing the viewer's eyes to naturally focus at different depths without the vergence-accommodation conflict experienced in 2D displays.
2Measurement precision
If multiview-type displays are used to recreate multiple views, then three-dimensional imaging is achieved, but light intensity is reduced and imaging resolution is lower
Solution Approach 1:
The patent combines multiple image planes into a single volumetric display volume. By projecting multiple planes (e.g., 9 planes) that intersect in three-dimensional space, the system merges the light from all planes into a unified volumetric image, thereby maintaining high light intensity while achieving true three-dimensional imaging with high resolution.
3Measurement precision
If volumetric-type displays use projection equipment to create three-dimensional images, then three-dimensional visualization is achieved, but image resolution is poor and full-colour representation is difficult
Solution Approach 1:
The patent segments the three-dimensional image into multiple two-dimensional planes that are then projected onto different planes within the display volume. Each plane can be rendered at high resolution independently, and their intersection creates a high-resolution volumetric image. This segmentation approach allows full-color representation and high image resolution to be achieved simultaneously in the volumetric display.
4Productivity
If sequences of three-dimensional images are displayed in real-time, then dynamic imaging is achieved, but computational complexity increases and data processing becomes intensive
Solution Approach 1:
The patent performs preliminary actions by pre-processing and segmenting the three-dimensional image data into multiple planes before projection. The system prepares the data structure in advance, organizing it into renderable planes that can be efficiently projected in sequence. This preliminary organization reduces real-time computational complexity while maintaining high frame rates for dynamic three-dimensional imaging.

AI summary
Displaying a sequence of three-dimensional images includes generating a data stream including a plurality of image planes associated with each image of the sequence of three-dimensional images, generating a bit-plane stream associated with the data stream, the bit-plane stream including a plurality of bit-planes associated with each image of the sequence of three-dimensional images, buffering the bit-plane stream asynchronously to provide a first plurality of bit-planes associated with a first three-dimensional image, and projecting a first plurality of image planes associated with the first three-dimensional image to display the first three-dimensional image, based upon the first plurality of bit-planes, the first plurality of image planes being projected until a second plurality of bit-planes associated with a second three-dimensional image is provided.
