Class CellBufferRenderer

Manages the GPU-side rendering pipeline for a text mode cell grid. Maintains a UnityEngine.GraphicsBuffer containing Cell data and renders the grid using instanced quad rendering via RenderMeshIndirect(in RenderParams, Mesh, GraphicsBuffer, int, int). Supports partial buffer updates to minimize GPU transfer costs.

Syntax

public class CellBufferRenderer : IDisposable

Properties

IsInitialized

Gets whether the renderer is initialized and ready to draw.

Declaration

public bool IsInitialized { get; }

Property Value

Type	Description
bool

Material

Gets the material used for rendering. Allows external configuration of shader properties.

Declaration

public Material Material { get; }

Property Value

Type	Description
Material

Methods

Dispose()

Releases all GPU resources.

Declaration

public void Dispose()

Initialize(int, int, Texture2D)

Initializes the renderer with the specified grid dimensions and font atlas.

Declaration

public void Initialize(int rows, int columns, Texture2D atlasTexture)

Parameters

Type	Name	Description
int	rows	Number of grid rows.
int	columns	Number of grid columns.
Texture2D	atlasTexture	The SDF font atlas texture.

Render(Vector2, Vector3, float, float, int)

Renders the cell grid at the specified world position.

Declaration

public void Render(Vector2 cellSize, Vector3 origin, float blinkTimer, float textBlinkTimer, int layer = 0)

Parameters

Type	Name	Description
Vector2	cellSize	Size of each cell in world units (x=width, y=height).
Vector3	origin	World-space origin of the grid (top-left corner).
float	blinkTimer	Current cursor blink timer value (0-1).
float	textBlinkTimer	Current text blink timer value (0-1).
int	layer	Rendering layer.

Resize(int, int)

Updates the grid dimensions. Recreates the GPU buffers.

Declaration

public void Resize(int rows, int columns)

Parameters

Type	Name	Description
int	rows	New number of rows.
int	columns	New number of columns.

UploadFull(Cell[])

Uploads the full cell array to the GPU buffer.

Declaration

public void UploadFull(Cell[] cells)

Parameters

Type	Name	Description
Cell[]	cells	The cell array to upload.

UploadPartial(Cell[], int, int)

Uploads a partial range of the cell array to the GPU buffer. Only the dirty range is transferred, reducing GPU bandwidth usage.

Declaration

public void UploadPartial(Cell[] cells, int startIndex, int count)

Parameters

Type	Name	Description
Cell[]	cells	The full cell array.
int	startIndex	Start index of the dirty range.
int	count	Number of cells in the dirty range.
