Class SpatialNodeSet

Namespace: ValveResourceFormat.Renderer
Assembly: Renderer.dll

Spatial set for the scene nodes that move. Flat rather than hierarchical: relocating a node is six float stores and culling is a linear pass over bounds laid out for SIMD.

public class SpatialNodeSet : ISpatialSet

Inheritance

object ← SpatialNodeSet

Implements

ISpatialSet

Properties

Count

Gets the number of nodes in the set.

public int Count { get; }

Property Value

int

DebugRenderer

Gets or sets the debug visualization renderer for this set.

public SpatialNodeSetDebugRenderer? DebugRenderer { get; set; }

Property Value

SpatialNodeSetDebugRenderer?

Dirty

Gets or sets whether the set needs rebuilding from the scene's node list.

public bool Dirty { get; set; }

Property Value

bool

Methods

Clear()

Removes every node from the set.

public void Clear()

GetBounds()

Returns the bounds covering every node in the set, or an empty box when it has none.

public AABB GetBounds()

Returns

AABB

GetNodes()

Returns the nodes currently in the set, for debug visualization.

public ReadOnlySpan<SceneNode> GetNodes()

Returns

ReadOnlySpan<SceneNode>

Insert(SceneNode)

Adds a node to the set and records its current bounds.

public void Insert(SceneNode node)

Parameters

node SceneNode

Query(Frustum, List<SceneNode>)

Appends every node whose bounds intersect the frustum, testing a vector of nodes at a time.

public void Query(Frustum frustum, List<SceneNode> results)

Parameters

frustum Frustum

results List<SceneNode>

Query(in AABB, List<SceneNode>)

Appends every node whose bounds intersect the given box.

public void Query(in AABB bounds, List<SceneNode> results)

Parameters

bounds AABB

results List<SceneNode>

Update(SceneNode)

Refreshes a node's stored bounds. Nodes that are not in the set, because their layer is off or the set has been rebuilt since, are ignored.

public void Update(SceneNode node)

Parameters

node SceneNode
