Inherits: Object
Namespace for the library's enums. Never instantiated -- it holds constants and nothing else.
Enumerations
enum ThicknessSpace
- SPACE_METERS = 0
- Thickness in world units; shrinks on screen with distance.
- SPACE_PIXELS = 1
- Thickness in screen pixels; constant on-screen size.
- SPACE_VIEWPORT = 2
- A fraction of the viewport: 100 span its shorter side, so 1 is one percent of it and about 11 pixels at 1080p. The same idea as CSS
vmin. Radii and sizes here are whole-ish numbers; strokes come out below 1, and a stroke that should stay a fixed pixel width wantsSPACE_PIXELSinstead.
enum LineEndCap
- CAP_NONE = 0
- Cut off exactly at each endpoint.
- CAP_SQUARE = 1
- Extend by half the thickness at each endpoint.
- CAP_ROUND = 2
- Extend by half the thickness, rounded.
enum LineGeometry
- LINE_BILLBOARD = 1
- A flat quad that turns to face the camera.
- LINE_VOLUMETRIC = 2
- Real tube geometry, with volume.
enum ColorMode
- COLOR_SINGLE = 0
- One flat color.
- COLOR_RADIAL = 1
- Interpolate
colortocolor_endfrom the center outwards. - COLOR_ANGULAR = 2
- Interpolate
colortocolor_endaround the sweep.
enum PolylineJoin
- JOIN_SIMPLE = 0
- Corners at plain half-width; the outside of a corner pinches inward.
- JOIN_MITER = 1
- Corners extended to where the edges meet, clamped on sharp turns.
- JOIN_ROUND = 2
- As simple, with a disc laid over each joint.
- JOIN_BEVEL = 3
- The outside of a corner cut off square.
enum BlendMode
- BLEND_OPAQUE = 0
- Writes depth and sorts against other geometry; hard edges, no fade.
- BLEND_TRANSPARENT = 1
- Standard alpha compositing. The default.
- BLEND_ADDITIVE = 2
- Brightens what is behind. Good for glows.
- BLEND_MULTIPLY = 3
- Darkens what is behind. Good for tints.
- BLEND_SUBTRACT = 4
- Subtracts this color from the background.
- BLEND_TRANSPARENT_DEPTH = 5
- Transparent, but writing depth so shapes occlude by position.
enum DashSpace
- DASH_METERS = 0
- Dash size and spacing are lengths in the shape's own units.
- DASH_RELATIVE = 1
- Dash size and spacing are multiples of the wall thickness.
- DASH_FIXED_COUNT = 2
- Dash size is a repeat count; spacing is the empty fraction of a period.
enum DashSnap
- SNAP_OFF = 0
- Use the dash period as given.
- SNAP_TILING = 1
- Round to a whole number of periods so the pattern tiles seamlessly.
- SNAP_END_TO_END = 2
- Round so a dash lands at each end of the shape.
enum DashType
- DASH_BASIC = 0
- Square dash ends.
- DASH_ANGLED = 1
- Dash ends sheared into a parallelogram. The shear is 0 by default, which looks exactly like
DASH_BASIC; setdash_modifieronGeomDraw, ormodifieronGeomDash. - DASH_ROUNDED = 2
- Rounded dash ends.
enum DiscType
- DISC_DISC = 0
- Filled circle.
- DISC_PIE = 1
- Filled circular sector, bounded by the start and end angle.
- DISC_RING = 2
- Hollow ring.
radiusis to the middle of the wall, not the outer edge. - DISC_ARC = 3
- A section of a ring, bounded by the start and end angle.
