enum Mode

enumerator M_unchanged = 0

enumerator M_filled = 1

Normal, filled polygons.

enumerator M_wireframe = 2

Wireframe polygons, possibly with thickness.

enumerator M_point = 3

Points at vertices only, possibly with thickness andor perspective sizing.

enumerator M_filled_flat = 4

Filled polygons, without any particular emphasis on perspective correctness (a particularly useful designation for software rendering sprites).

enumerator M_filled_wireframe = 5

Filled polygons with wireframe rendered in front. The wireframe is given a solid color.

static RenderModeAttrib.get_class_slot()

static RenderModeAttrib.get_class_type()

RenderModeAttrib.get_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.

RenderModeAttrib.get_mode()

Returns the render mode.

RenderModeAttrib.get_perspective()

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.

RenderModeAttrib.get_thickness()

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).

RenderModeAttrib.get_wireframe_color()

Returns the color that is used in M_filled_wireframe mode to distinguish the wireframe from the rest of the geometry.

static RenderModeAttrib.make()

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.

In M_filled_wireframe mode, you should also specify the wireframe_color, indicating the flat color to assign to the overlayed wireframe.

static RenderModeAttrib.make_default()

Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.
