getDisplayTransformation()

const visBase::Transformation* visBase::TextureRectangle::getDisplayTransformation ( ) const

All positions going from the outside world to the vis should be transformed with this transform. This enables us to have different coord-systems outside OI, e.g. we can use UTM coords outside the vis without loosing precision in the vis.

Reimplemented from visBase::DataObject.

isDisplayFrozen()

const

As long as texture rectangle is frozen, the display of (lengthy) changes to its geometry and/or texture is postponed. Avoids showing half-finished updates.

setDisplayTransformation()

overridevirtual

All positions going from the outside world to the vis should be transformed with this transform. This enables us to have different coord-systems outside OI, e.g. we can use UTM coords outside the vis without loosing precision in the vis.

Reimplemented from visBase::DataObject.

setRotation()

void visBase::TextureRectangle::setRotation	(	const Coord3 &	spanvec0,
		const Coord3 &	spanvec1
	)

Aligns rectangle to both spanning vectors.

setRotationAndWidth()

void visBase::TextureRectangle::setRotationAndWidth	(	const Coord3 &	spanvec0,
		const Coord3 &	spanvec1
	)

Aligns rectangle to both spanning vectors, and calls setWidth(.) using their lengths.

setTextureGrowth()

void visBase::TextureRectangle::setTextureGrowth

(

Size increase/decrease of the texture envelope (in pixel units). Its default size is one pixel shorter than the image envelope (half-a-pixel at every border).

setTextureShift()

void visBase::TextureRectangle::setTextureShift

(

const Coord &

)

Shift of the texture envelope center (in pixel units) with regard to the center of the plane geometry.

setWidth()

void visBase::TextureRectangle::setWidth

One dim must be set zero.
