Re: [PlayerStage-Gazebo] Creating my own terrain

[Nate K. <nat...@gm...>]

Hi Carlos,

The grid.ppm is just a texture image.The terrain.png is the grayscale
images that specifies the shape of the landscape. Each pixel is
interpreted as a height value, where white pixels are at the maximum
height and black at the minimum.
