TopologyAdapter

ClassChartGuruChartGuru

public class TopologyAdapter : IChartDrawSink

Decorator over an ChartGuru.IChartDrawSink that only natively accepts ChartGuru.DrawTopology.Triangles and synthesizes the other topologies by buffering the incoming vertex stream per batch and converting on ChartGuru.TopologyAdapter.End.

• `ChartGuru.DrawTopology.Quads` → two triangles per 4-vertex group (0,1,2) + (0,2,3).
• `ChartGuru.DrawTopology.Lines` → `ChartGuru.LineTessellator.TessellateLines(System.Collections.Generic.IReadOnlyList%7bUnityEngine.Vector2%7d%2cSystem.Single%2cSystem.Collections.Generic.List%7bUnityEngine.Vector2%7d)` with the configured `ChartGuru.TopologyAdapter.LineWidth`.
• `ChartGuru.DrawTopology.LineStrip` → `ChartGuru.LineTessellator.TessellatePolyline(System.Collections.Generic.IReadOnlyList%7bUnityEngine.Vector2%7d%2cSystem.Single%2cSystem.Boolean%2cSystem.Collections.Generic.List%7bUnityEngine.Vector2%7d)`.

The adapter buffers color per vertex so per-vertex gradients survive the topology conversion. Colors are replayed into the underlying sink between vertices.

Properties

LineWidth

public float LineWidth { get; set; }

Stroke width used when flattening ChartGuru.DrawTopology.Lines/ChartGuru.DrawTopology.LineStrip.

Returns

System.Single — No return description is available.

Constructors

TopologyAdapter(IChartDrawSink)

public TopologyAdapter(IChartDrawSink inner)

No description is available for this member.

Parameters

Name	Type	Description
inner	ChartGuru.IChartDrawSink

Methods

Begin(DrawTopology, DrawMaterial)

public void Begin(DrawTopology topology, DrawMaterial material = DrawMaterial.Standard)

Begins a primitive batch with the given topology and material bucket. Must be balanced with ChartGuru.IChartDrawSink.End before another ChartGuru.IChartDrawSink.Begin(ChartGuru.DrawTopology%2cChartGuru.DrawMaterial).

Parameters

Name	Type	Description
topology	ChartGuru.DrawTopology
material	ChartGuru.DrawMaterial

Color(Color)

public void Color(Color c)

Sets the current vertex color. Applies to all subsequently emitted vertices until overridden.

Parameters

Name	Type	Description
c	UnityEngine.Color

Vertex(float, float)

public void Vertex(float x, float y)

Emits a vertex at the specified chart-space pixel coordinate (Y up, bottom-left origin).

Parameters

Name	Type	Description
x	System.Single
y	System.Single

End()

public void End()

Closes the current primitive batch started by ChartGuru.IChartDrawSink.Begin(ChartGuru.DrawTopology%2cChartGuru.DrawMaterial).

SetScissor(Rect?)

public void SetScissor(Rect? clipRectPixels)

Sets an axis-aligned scissor rectangle in pixel coordinates, or clears it when null. Intended for morph and inset panels; the GL sink translates this to an SRP scissor, the UI Toolkit sink to a clipping descendant or manual CPU-side clipping.

Parameters

Name	Type	Description
clipRectPixels	System.Nullable{UnityEngine.Rect}

PushTransform(Matrix4x4)

public void PushTransform(Matrix4x4 m)

Pushes a transform onto the sink’s matrix stack. Subsequent ChartGuru.IChartDrawSink.Vertex(System.Single%2cSystem.Single) calls are effectively multiplied by the top-of-stack matrix. Matches GL.PushMatrix + GL.MultMatrix(m).

Parameters

Name	Type	Description
m	UnityEngine.Matrix4x4

PopTransform()

public void PopTransform()

Pops the top matrix from the sink’s transform stack. Matches GL.PopMatrix.
