CreateGlgMatrixData()

GlgMatrixData CreateGlgMatrixData	(	GlgXformType	type,
		Float64Array	array
	)

Constructor.

Creates a matrix data object that can be used as a parameter of the SetMatrixData method.

The static method is invoked on the GLG Toolkit handle obtained via a 'new GlgToolkit()' call at the application start-up.

Parameters

type	A type of the matrix (one of constants defined in the GlgXformType enum).
array	An array of 16 (4x4) matrix coefficients.

Returns

A new GlgMatrixData object.

ReleaseToCache()

static void ReleaseToCache ( GlgMatrixData  obj )

static

Returns the object to the internal cache for reuse.

The object should not be accessed after it is released to the cache.

The static method is invoked on the GLG Toolkit handle obtained via a 'new GlgToolkit()' call at the application start-up.

Parameters

obj	The object to release.
