MPSImageTent(3) MetalPerformanceShaders.framework MPSImageTent(3)NAMEMPSImageTentSYNOPSIS#import <MPSImageConvolution.h> Inherits MPSImageBox. Additional Inherited Members Detailed Description The box filter, while fast, may yield square-ish looking blur effects. However, multiple passes of the box filter tend to smooth out with each additional pass. For example, two 3-wide box blurs produces the same effective convolution as a 5-wide tent blur: 1 1 1 1 1 1 + 1 1 1 ================= 1 2 3 2 1 Addition passes tend to approximate a gaussian line shape. The MPSImageTent convolves an image with a tent filter. These form a tent shape with incrementally increasing sides, for example: 1 2 3 2 1 1 2 1 2 4 2 1 2 1 Like the box filter, this arrangement allows for much faster algorithms, espcially for for larger blur radii but with a more pleasing appearance. The tent blur is a separable filter. The implementation is aware of this and will act accordingly to give best performance for multi- dimensional blurs.
