Class: GraphicsGeometry

PIXI.GraphicsGeometry

The Graphics class contains methods used to draw primitive shapes such as lines, circles and rectangles to the display, and to color and fill them.

GraphicsGeometry is designed to not be continually updating the geometry since it's expensive to re-tesselate using earcut. Consider using PIXI.Mesh for this use-case, it's much faster.

Members

PIXI.GraphicsGeometry.BATCHABLE_SIZE number static

The maximum number of points to consider an object "batchable", able to be batched by the renderer's batch system.

Default Value:
  • 100

_bounds PIXI.Bounds protected

Cached bounds.

_buffer PIXI.Buffer protected inherited

Buffer used for position, color, texture IDs

_indexBuffer PIXI.Buffer protected inherited

Index buffer data

batchDirty number protected

Batches need to regenerated if the geometry is updated.

Used to detect if we cleared the graphicsData.

Default Value:
  • 0

closePointEps number

Minimal distance between points that are considered different. Affects line tesselation.
