| NoiseMapBuilder | Abstract base class for a noise-map builder A builder class builds a noise map by filling it with coherent-noise values generated from the surface of a three-dimensional mathematical object. Each builder class defines a specific three-dimensional surface, such as a cylinder, sphere, or plane. A builder class describes these input values using a coordinate system applicable for the mathematical object (e.g., a latitude/longitude coordinate system for the spherical noise-map builder.) It then "flattens" these coordinates onto a plane so that it can write the coherent-noise values into a two-dimensional noise map. Building the Noise Map To build the noise map, perform the following steps: - Pass the bounding coordinates to the SetBounds() method. - Pass the noise map size, in points, to the SetDestSize() method. - Pass a NoiseMap object to the SetDestNoiseMap() method. - Pass a noise module (derived from Noise.Module) to the SetSourceModule() method. - Call the Build() method. You may also pass a callback function to the SetCallback() method. The Build() method calls this callback function each time it fills a row of the noise map with coherent-noise values. This callback function has a single integer parameter that contains a count of the rows that have been completed. It returns void. Note that SetBounds() is not defined in the abstract base class; it is only defined in the derived classes. This is because each model uses a different coordinate system. |
| NoiseMapBuilderCylinder | Builds a cylindrical noise map. This class builds a noise map by filling it with coherent-noise values generated from the surface of a cylinder. This class describes these input values using an (angle, height) coordinate system. After generating the coherent-noise value from the input value, it then "flattens" these coordinates onto a plane so that it can write the values into a two-dimensional noise map. The cylinder model has a radius of 1.0 unit and has infinite height. The cylinder is oriented along the y axis. Its center is at the origin. The x coordinate in the noise map represents the angle around the cylinder's y axis. The y coordinate in the noise map represents the height above the x-z plane. The application must provide the lower and upper angle bounds of the noise map, in degrees, and the lower and upper height bounds of the noise map, in units. |
| NoiseMapBuilderPlane | Builds a planar noise map. This class builds a noise map by filling it with coherent-noise values generated from the surface of a plane. This class describes these input values using (x, z) coordinates. Their y coordinates are always 0.0. The application must provide the lower and upper x coordinate bounds of the noise map, in units, and the lower and upper z coordinate bounds of the noise map, in units. To make a tileable noise map with no seams at the edges, use the Seamless property. |
| NoiseMapBuilderSphere | Builds a spherical noise map. This class builds a noise map by filling it with coherent-noise values generated from the surface of a sphere. This class describes these input values using a (latitude, longitude) coordinate system. After generating the coherent-noise value from the input value, it then "flattens" these coordinates onto a plane so that it can write the values into a two-dimensional noise map. The sphere model has a radius of 1.0 unit. Its center is at the origin. The x coordinate in the noise map represents the longitude. The y coordinate in the noise map represents the latitude. The application must provide the southern, northern, western, and eastern bounds of the noise map, in degrees. |
