A default get_seamless_noise() implementation is provided for libraries that do not provide seamless noise. This function requests a larger image from get_image(), reverses the quadrants of the image, then uses the strips of extra width to blend over the seams. Inheriting noise classes can optionally override this function to provide a more optimal algorithm. </description> <tutorials> </tutorials> <methods> <method name="get_image" qualifiers="const"> <return type="Image" /> <argument index="0" name="width" type="int" /> <argument index="1" name="height" type="int" /> <argument index="2" name="invert" type="bool" default="false" /> <argument index="3" name="in_3d_space" type="bool" default="false" /> <description> Returns a 2D [Image] noise image. </description> </method> <method name="get_noise_1d" qualifiers="const"> <return type="float" /> <argument index="0" name="x" type="float" /> <description> Returns the 1D noise value at the given (x) coordinate. </description> </method> <method name="get_noise_2d" qualifiers="const"> <return type="float" /> <argument index="0" name="x" type="float" /> <argument index="1" name="y" type="float" /> <description> Returns the 2D noise value at the given position. </description> </method> <method name="get_noise_2dv" qualifiers="const"> <return type="float" /> <argument index="0" name="v" type="Vector2" /> <description> Returns the 2D noise value at the given position. </description> </method> <method name="get_noise_3d" qualifiers="const"> <return type="float" /> <argument index="0" name="x" type="float" /> <argument index="1" name="y" type="float" /> <argument index="2" name="z" type="float" /> <description> Returns the 3D noise value at the given position. </description> </method> <method name="get_noise_3dv" qualifiers="const"> <return type="float" /> <argument index="0" name="v" type="Vector3" /> <description> Returns the 3D noise value at the given position. </description> </method> <method name="get_seamless_image" qualifiers="const"> <return type="Image" /> <argument index="0" name="width" type="int" /> <argument index="1" name="height" type="int" /> <argument index="2" name="invert" type="bool" default="false" /> <argument index="3" name="in_3d_space" type="bool" default="false" /> <argument index="4" name="skirt" type="float" default="0.1" /> <description> Returns a seamless 2D [Image] noise image. </description> </method> </methods> </class>
