Hey,
I’m trying to use Splash for mapping a small dome on a budget, using just two short throw projectors. Works well, even on Windows, managed to get two separate outputs work.
With two projectors and and only 2v frequency of the dome there are unavoidable artifacts where the images meet/overlap. I smoothed some of them with warping but in this situation the 8x8 maximum on warping resolution is limiting.
Is there a way of adjusting the warp to allow higher than 8x8?
Hello @w1d3, and welcome to this forum!
I’m glad that you got Splash running on Windows, thanks for the information. If you see issues which seem specific to Windows, or any other issue, do not hesitate to mention it 
Regarding warping, I did not have any use case for more that 8x8. But I should be able to allow for higher values. What would be a good range in your own experience?
I feel like I would need at least 4 times the resolution (32x32) to achieve considerably better results. But that seems like it would be a hell to move so many points.
So another approach that I have seen in other softwares is to use a multi-layer warp map. For example 8x8 warp layer for coarse warping, and then another layer with higher resolution (16x16) that would be applied on top of the first one to allow for fine warping, only for areas that need it… and possibly another layer for even finer adjustments. In that case you need to move only subset of the control points, which would be manageable. Does it make sense?
