Documentation

creates mpolys for various types of terrain. The most useful methods are generateRock() and createRocksFromDistribution().

enum terrainMode

List of modes for terrain generation.

• FROM_EVALUTOR - Evaluator will make explicit calls to terrainGenerator methods to create terrain
• FLAT - generate a flat terrain when init() is called
• SINUSOID - generate a sinusoidal terrain when init() is called
• RANDOM - generate a random terrain when init() is called

enum rockDistribution

List of predefined distributions based on Mars data.

• COVERAGE_10: 10% coverage of ground by discrete rocks
• COVERAGE_20: 20% coverage of ground by discrete rocks
• COVERAGE_30: 30% coverage of ground by discrete rocks
• COVERAGE_40: 40% coverage of ground by discrete rocks
