Detailed Description

sonus::Integrator

Class for integration / migration of level data into single modules. Contains only static methods. The raw data of a level based on a SVG must be transformed so every module can work with the level because the modules have different number workspaces. If a module changes level data it needs to retransform those values. Besides that the class has some other utility functions

Member Function Documentation

static void sonus::Integrator::getTransformAndScaleFactor	(	Level2D *	level,
		Vector2D *	destinationOrigin,
		double	maxValue,
		Vector2D *	transformationVector,
		double *	scaleFactor
	)			[inline, static]

Calculates a transformation vector and scale factor to transform level data into module workspace and scaling. It is assumed that the module workspace is cubic. For example your level has its origin at (0, 0) and a max value of 50. So the level workspace goes from (-50, -50) to (50, 50). Assuming your module has its origin at (10, 10) and also a max value at 50. So its workspace goes from (-40, -40) to (60, 60). So the transformation vector will be (10, 10) and the scale factor will be 1.

Parameters:

	level	the level (data)
	destinationOrigin	the origin coordinates of the module workspace
	maxValue	the max value of the workspace
	transformationVector	the output transformation vector
	scaleFactor	the output scale factor
