Class LineBuffer

Namespace: ValveResourceFormat.Renderer
Assembly: Renderer.dll

Vertex array/buffer pair for drawing a colored line list with the default shader.

public class LineBuffer

Inheritance

object ← LineBuffer

Constructors

LineBuffer(RendererContext, string, string)

Creates the GL objects and binds the shader's layout.

public LineBuffer(RendererContext rendererContext, string label, string shaderName = "default")

Parameters

rendererContext RendererContext

Renderer context for loading the shader.

label string

Debug label of the GL objects.

shaderName string

Shader the lines are drawn with, taking a position and color per vertex.

Properties

Shader

The default shader the vertex layout is bound to.

public Shader Shader { get; }

Property Value

Shader

VertexCount

Number of vertices currently uploaded.

public int VertexCount { get; }

Property Value

int

Methods

Clear()

Drops the uploaded vertices.

public void Clear()

Delete()

Deletes the GL objects.

public void Delete()

Draw(uint)

Draws the lines, with the object id as instancing base for picking.

public void Draw(uint objectId = 0)

Parameters

objectId uint

Object id used as instancing base for picking.

Draw(int, int, uint, PrimitiveType)

Draws a range of the uploaded vertices, with the object id as instancing base for picking.

public void Draw(int first, int count, uint objectId = 0, PrimitiveType primitive = PrimitiveType.Lines)

Parameters

first int

Index of the first vertex to draw.

count int

Number of vertices to draw, two per segment or three per triangle.

objectId uint

Object id used as instancing base for picking.

primitive PrimitiveType

What the vertices make up.

Upload(List<SimpleVertex>)

Uploads the line vertices, two per segment.

public void Upload(List<SimpleVertex> vertices)

Parameters

vertices List<SimpleVertex>

Upload(ReadOnlySpan<SimpleVertex>)

Uploads the line vertices, two per segment.

public void Upload(ReadOnlySpan<SimpleVertex> vertices)

Parameters

vertices ReadOnlySpan<SimpleVertex>
