erosion sim ideas
« on: November 18, 2012, 06:37:17 PM »
first open the grayscale png elevation map, then read all the pixels and put the greyscale values into an array
def erosion(c):
    lower the value of c
    look around at all the pixels around c to see if any are lower (in all 8 directions)
    set the pixel with the lowest elevation to c
    if none are lower set c to a pixel
run erosion(c) x times.
write this all into the png file.

any suggestions for improvement would be nice

OH, oh, after i get past the basic step i can use one of the three rgb channels to generate the hardness of a material!.

OH, and the steeper the slope the more the erosion should be.

@atomic
my idea was for the input to be a png file, grayscale values denoting height, and the output to be a modified png file, grayscale values denoting the height. i don't know what you need the erosion simulation thing for so not sure if what i had in mine is what you had in mind?

yes it is except the input and output is so much better.

Okay maybe not but it's decent. I just want to simulate rivers (a small section of it not like 500 km long more like 500 m long). Cause rivers are cool. Also other erosions are nice too.
