Philips provides autostereoscopic three-dimensional display systems that will bring the next leap in visual experience, adding true depth to video systems. We identified three challenges specifically for 3D image processing: 1) bandwidth and complexity of 3D images, 2) conversion of 2D to 3D content, and 3) object-based image/depth processing. We discuss these challenges and our solutions via several examples. In conclusion, the solutions have enabled the market introduction of several professional 3D products, and progress is made rapidly towards consumer 3DTV.

We propose to use quadratic Bezier triangles as additional drawing primitives: quadratic Bezier triangles require much less model data for faithful representation of curved surfaces than planar triangles. Therefore, they require less storage and/or transmission capacity. Furthermore, they allow automatic level-of-detail. Finally, they result in considerable savings in model-view transformations and lighting calculations. We present two algorithms for rendering these triangles, each of which can be easily incorporated in hardware render systems currently used for planar triangles.
