Op * TransformGeo::default_input ( int input ) const

virtual

Return a null geo for input0 and NULL for any other.

Reimplemented from DD::Image::GeoOp.

References DD::Image::GeoOp::default_input().

bool TransformGeo::test_input	(	int	input,
		Op *	op
	)		const

virtual

Only GeoOp allowed on zero, only AxisOp allowed on 1

Reimplemented from DD::Image::GeoOp.

void TransformGeo::_validate ( bool for_real )

protectedvirtual

Validate our parent axis first, if any, then apply our local transform to that.

Reimplemented from DD::Image::GeoOp.

References DD::Image::Op::_validate(), concat_input_, concat_matrix_, DD::Image::LookAt::lookAt(), lookat_input(), matrix_, DD::Image::LookAt::my_local, DD::Image::Op::parent(), DD::Image::GeoOp::update_geometry_hashes(), and DD::Image::Op::validate().

void TransformGeo::get_geometry_hash ( )

protectedvirtual

Hash the matrix so that any change causes the points to be invalid.

Reimplemented from DD::Image::GeoOp.

References DD::Image::Matrix4::append(), DD::Image::GeoOp::geo_hash, DD::Image::GeoOp::get_geometry_hash(), lookat_input(), DD::Image::LookAt::lookat_matrix_, and matrix_.

void TransformGeo::geometry_engine	(	Scene &	scene,
		GeometryList &	out
	)

protectedvirtual

Apply the concat matrix to all the GeoInfos.

Reimplemented from DD::Image::GeoOp.

References concat_input_, concat_matrix_, DD::Image::GeoOp::get_geometry(), and DD::Image::GeometryList::size().

void TransformGeo::build_handles ( ViewerContext * ctx )

protectedvirtual

The default GeoOp::build_handles will build a Scene object and draw it. This is not needed by TransformGeo, as it can just change the OpenGL transform and then ask the input to draw. Also the Axis knobs do not draw right unless it sets the transform for any parent transform.

Reimplemented from DD::Image::GeoOp.
