Hi friends,
I’m developing an application that uses the warp function. I achieve deformation by defining and connecting control points.
This is not difficult to achieve when using straight lines to connect control points. But if I need to connect the control points with a curve, how do I do that?
Aa curve is simulated with lots of straight lines, does this mean that this requires adding lots of points and then using NvAPI_GPU_SetScanoutWarping(dispIds[dispIndex].displayId, &warpingData, &maxNumVertices, &sticky); ?
Interpolation is done automatically. Just give the coordinates of the point in un-warped and warped space and you will see, that the warping is nice and without “edges”. Remember that you need to specify vertices.
