Sharpens a height field using different convolution kernels.
Use this if you think your terrain looks too soft or too round, and you want more detail without actually adding new features.
Select a kernel here that looks good to you. Each kernel has a distinct look, and its own advantages. Some will get quirky when pushed too far.
The following are available:
- Frank's Sharpen Kernel, variable
This is a modified Sharpen kernel that can be stretched to almost any radius. With small radii it can bring out the details nicely (especially if you increase the Emphasize attribute), with larger radii it gets quite weird.
- Sharpen 3x3
The classic 3x3 sharpen kernel. Crisp details.
- Unsharp Masking 5x5
A subtle 5x5 Unsharp Masking kernel. Looks less obvious than the 3x3 Sharpen.
- Unsharp Masking, variable
An Unsharp Masking kernel with variable size. The slowest of the available kernels.
The radius of the sharpen kernel. Larger values will sharpen the larger features more, and result in a more coarse look. This attribute is only available for the ‘variable’ kernels.
Increase this to emphasize the results of ‘Frank's Sharpen Kernel’.
