int RenderModeAttrib::compare_to_impl ( const RenderAttrib * other ) const [protected, virtual]

Intended to be overridden by derived RenderModeAttrib types to return a unique number indicating whether this RenderModeAttrib is equivalent to the other one.

This should return 0 if the two RenderModeAttrib objects are equivalent, a number less than zero if this one should be sorted before the other one, and a number greater than zero otherwise.

This will only be called with two RenderModeAttrib objects whose get_type() functions return the same.

Reimplemented from RenderAttrib.

Definition at line 121 of file renderModeAttrib.cxx.

void RenderModeAttrib::fillin	(	DatagramIterator &	scan,
		BamReader *	manager
	)		`[protected, virtual]`

This internal function is called by make_from_bam to read in all of the relevant data from the BamFile for the new RenderModeAttrib.

Reimplemented from RenderAttrib.

int RenderModeAttrib::get_geom_rendering ( int geom_rendering ) const [inline]

Returns the union of the Geom::GeomRendering bits that will be required once this RenderModeAttrib is applied to a geom which includes the indicated geom_rendering bits.

Referenced by RenderState::get_geom_rendering().

size_t RenderModeAttrib::get_hash_impl ( ) const [protected, virtual]

Intended to be overridden by derived RenderAttrib types to return a unique hash for these particular properties.

RenderAttribs that compare the same with compare_to_impl(), above, should return the same hash; RenderAttribs that compare differently should return a different hash.

Reimplemented from RenderAttrib.

RenderModeAttrib::Mode RenderModeAttrib::get_mode ( ) const [inline]

Returns the render mode.

Definition at line 37 of file renderModeAttrib.I.

Referenced by NodePath::get_render_mode().

bool RenderModeAttrib::get_perspective ( ) const [inline]

Returns the perspective flag.

When this is true, the point thickness represented by get_thickness() is actually a width in 3-d units, and the points should scale according to perspective. When it is false, the default, the point thickness is actually a width in pixels, and points are a uniform size regardless of distance from the camera.

Definition at line 67 of file renderModeAttrib.I.

Referenced by NodePath::get_render_mode_perspective().

PN_stdfloat RenderModeAttrib::get_thickness ( ) const [inline]

Returns the line width or point thickness.

This is only relevant when rendering points or lines, such as when the mode is M_wireframe or M_point (or when rendering actual points or lines primitives in M_polygon mode).

TypedWritable * RenderModeAttrib::make_from_bam ( const FactoryParams & params ) [static, protected]

This function is called by the BamReader's factory when a new object of type RenderModeAttrib is encountered in the Bam file.

It should create the RenderModeAttrib and extract its information from the file.

void RenderModeAttrib::register_with_read_factory ( ) [static]

Tells the BamReader how to create objects of type RenderModeAttrib.

void RenderModeAttrib::write_datagram	(	BamWriter *	manager,
		Datagram &	dg
	)		`[virtual]`

Writes the contents of this object to the datagram for shipping out to a Bam file.
