[static]

Reimplemented from RenderAttrib.

int getGeomRendering

(

int

geom_rendering

)

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.

Mode getMode

(

)

Returns the render mode.

bool getPerspective

(

)

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.

float getThickness

(

)

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).

static RenderAttrib const make	(	Mode	mode,
		float	thickness
	)		[static]

Constructs a new RenderModeAttrib object that specifies whether to draw polygons in the normal, filled mode, or wireframe mode, or in some other yet-to-be-defined mode.

The thickness parameter specifies the thickness to be used for wireframe lines, as well as for ordinary linestrip lines; it also specifies the diameter of points. (Thick lines are presently only supported in OpenGL; but thick points are supported on either platform.)

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

static RenderAttrib const make	(	Mode	mode,
		float	thickness,
		bool	perspective
	)		[static]

Constructs a new RenderModeAttrib object that specifies whether to draw polygons in the normal, filled mode, or wireframe mode, or in some other yet-to-be-defined mode.

The thickness parameter specifies the thickness to be used for wireframe lines, as well as for ordinary linestrip lines; it also specifies the diameter of points. (Thick lines are presently only supported in OpenGL; but thick points are supported on either platform.)

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