Detailed Description

A handle to scale the selected object uniformly in 3 dimensions.

This class represents a central scaling handle that can be used to scale an object uniformly in all 3 dimensions. The user can drag horizontally, increasing the uniform scaling by dragging to the right, and decreasing by dragging to the left of the origin.

The mesh used for the manipulator is a central cube.

Member Function Documentation

void GLScaleUniformHandle::applyXformToLocation	(	const std::string &	locationPath,
		const IMATH_NAMESPACE::M44d &	xform,
		bool	isFinal
	)		[protected, virtual]

Applies the given scale transform to the given location.

Implements Foundry::Katana::ViewerUtils::GLTransformManipulatorHandle.

void GLScaleUniformHandle::drag	(	const Vec3d &	initialPointOnPlane,
		const Vec3d &	previousPointOnPlane,
		const Vec3d &	currentPointOnPlane,
		const Vec2i &	initialMousePosition,
		const Vec2i &	previousMousePosition,
		const Vec2i &	currentMousePosition,
		bool	isFinal
	)		[protected, virtual]

Detects the amount of scale and applies it to all the manipulated locations.

Reimplemented from Foundry::Katana::ViewerUtils::GLTransformManipulatorHandle.

void GLScaleUniformHandle::draw

(

)

[virtual]

Draws the handle.

Reimplemented from Foundry::Katana::ViewerUtils::GLTransformManipulatorHandle.

virtual std::string GLScaleUniformHandle::getComponentName

(

)

[inline, protected, virtual]

The transform component: xform.interactive.scale

Implements Foundry::Katana::ViewerUtils::GLTransformManipulatorHandle.

bool GLScaleUniformHandle::getDraggingPlane	(	Vec3d &	origin,
		Vec3d &	normal
	)		[protected, virtual]

Gets the dragging plane's origin and normal. The origin is always the same as the in whole manipulator and the the normal is given by the camera direction (inverted).

Reimplemented from Foundry::Katana::ViewerUtils::GLManipulatorHandle.

void GLScaleUniformHandle::pickerDraw

(

int64_t

pickerId

)

[virtual]

Draws the manipulator with a specific selection picker ID. Typically this ID is converted to a color value, and the handle is then drawn with flat shading, so it can be identified in a look-up table.

Reimplemented from Foundry::Katana::ViewerUtils::GLTransformManipulatorHandle.
