Detailed Description

Subclass of GeoOp that does not take another GeoOp as input. This alters the control panel knobs and tooltips slightly to avoid references to the input geometry.

Constructor & Destructor Documentation

SourceGeo::SourceGeo

(

Node *

node

)

Constructs a single texture input.

References DD::Image::GeoOp::display3d_, DD::Image::Op::inputs(), and DD::Image::GeoOp::render_mode_.

Member Function Documentation

Iop * SourceGeo::input_iop

(

)

const

Returns the Iop connected to the texture input.

References DD::Image::Op::input0().

void SourceGeo::knobs

(

Knob_Callback

f

)

[virtual]

Calls the GeoOp baseclass with source_geo=true so that the display knobs are correct for a Source object.

Reimplemented from DD::Image::GeoOp.

References DD::Image::Divider(), and DD::Image::Knob::HIDDEN.

void SourceGeo::build_input_handles

(

ViewerContext *

ctx

)

Constructs the transform to apply before the iop input is followed.

Reimplemented from DD::Image::Op.

void SourceGeo::init_geoinfo_parms	(	Scene &	scene,
		GeometryList &	out
	)			[virtual]

Assign all the base parameters for each GeoInfo in the output GeometryList.

void SourceGeo::build_matrix_handles	(	ViewerContext *	ctx,
		Matrix4	localMatrix
	)			[protected]

build_handles with the context model matrix multiplied by the local matrix so nodes up the tree are displayed correctly

void SourceGeo::get_geometry_hash

(

)

[protected, virtual]

Hash up knobs that affect the geo's material.

void SourceGeo::geometry_engine	(	Scene &	scene,
		GeometryList &	out
	)			[protected, virtual]

SourceGeo subclass implementation calls geometry_engine() on each GeoInfo in the local cache list.
