Why i made my own? No real reason. It is fast and has very few options.
I was mostly trying to learn
playing with something called laplacian blend.
it is a really nice way of blending two textures where high and low frequencies in the image are blended at different mip levels so that things blend into oneanother in a really pleasing way.
as you can see there is none of the ghosting that an ordinary soft masks gives you.
it does a really nice job of blending heightfields. you can see that there is no loss of high frequency data and yet there is no discontinuity in height.
try it yourself!
