1. To get optimal resolution distributions, the writer proposed a method for generating a projection to match a desired resolution function, which allows for customized projections with smooth, continuous and optimal resolution functions.
2. The method can drastically improve compression ratios for any given quality compared to commonly used projections.
3. The writer believes that the ERP format has singularities, the cubic projection sacrifices adjacency and increases resolution, as for the pyramid format, the resolution away from the forward viewing direction is undesirable. (all have inherently disadvantages)
4. Using a resolution function similar to that of the human eye, the writer’s method derives a nearly optimal projection. As a result, their projection’s resolution function peaks in the forward viewing direction, with resolution smoothly decreasing in all directions.
5. To compare with other projections, the writer calculates the total resolution and total uniformity of the method. And uses 3 weighting functions, 1>impulse function in the forward direction, 2>foveate resolution function when looking forward, 3> empirical viewing patterns.
6. Conclusion: producing content with increased resolution and decreased distortion in important areas.
