Reimplemented from RenderAttrib.
unsigned short int getModeQuality | ( | ) |
Returns the specified antialias mode, with the type bits masked out.
This therefore indicates only the requested quality settings: one of M_faster, M_better, M_dont_care, or zero (unspecified).
unsigned short int getModeType | ( | ) |
Returns the specified antialias mode, with the quality bits masked out.
This therefore indicates only the requested type of antialiasing: M_none, M_auto, or some specific combination.
static RenderAttrib const make | ( | unsigned short int | mode | ) | [static] |
Constructs a new AntialiasAttrib object.
The mode should be either M_none, M_auto, or a union of any or all of M_point, M_line, M_polygon, and M_multisample. Also, in addition to the above choices, it may include either of M_better of M_faster to specify a performance/quality tradeoff hint.
If M_none is specified, no antialiasing is performed.
If M_multisample is specified, it means to use the special framebuffer multisample bits for antialiasing, if it is available. If so, the M_point, M_line, and M_polygon modes are ignored. This advanced antialiasing mode is only available on certain graphics hardware. If it is not available, the M_multisample bit is ignored (and the other modes may be used instead, if specified).
M_point, M_line, and/or M_polygon specify per-primitive smoothing. When enabled, M_point and M_line may force transparency on. M_polygon requires a frame buffer that includes an alpha channel, and it works best if the primitives are sorted front-to-back.
If M_auto is specified, M_multisample is selected if it is available, otherwise M_polygon is selected, unless drawing lines or points, in which case M_line or M_point is selected (these two generally produce better results than M_multisample)
static RenderAttrib const makeDefault | ( | ) | [static] |
Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.
