QMatrix4x4 Math::calculateModelViewProj	(	const QMatrix4x4 &	model,
		const QMatrix4x4 &	view,
		const QMatrix4x4 &	projection
	)			[static]

Calculate a Model-View-Projection matrix.

This type of matrix is used to transform vertices into screen space prior to rendering.

Parameters:

model

The object-space matrix. (Object's transformation) Parameters: view  The view matrix. (Camera's transformation) Parameters: projection  The projection matrix.

Definition at line 38 of file math.cpp.

void Math::qImageToGL	(	const QImage &	image,
		uchar *	out
	)			[static]

Convert a QImage to an array of unsigned chars.

This method will convert a 32 bits ARGB QImage to an RGBA array of unsigned chars.

Note that this method is mostly a workaround for stuff lacking from Qt.

Parameters:

image

The image to convert. Parameters: out  An array of unsigned chars to which the data needs to be copied.

Definition at line 44 of file math.cpp.

void Math::qmatrixToGLMatrix	(	const QMatrix4x4 &	matrix,
		float *	out
	)			[static]

Convert a QMatrix4x4 to a float array.

This will convert a QMatrix4x4 to an array of 16 floats which can be used by OpenGL's matrix functions, most notably glUniformMatrix4fv.

Note that this method is mostly a workaround for stuff lacking from Qt.

Parameters:

matrix

The QMatrix to convert. Parameters: out  An array of 16 floats into which the converted matrix will be copied.
