Class HammerOverlayBuilder

Namespace: ValveResourceFormat.IO
Assembly: ValveResourceFormat.dll

Rebuilds a from its projected map geometry, this code attempts to figure out the source mesh the overlay was projected from.

public static class HammerOverlayBuilder

Inheritance

object ← HammerOverlayBuilder

Fields

MeshHeight

How far above the surface the reconstructed overlay mesh should sit.

public const float MeshHeight = 16

Field Value

float

ProjectionMargin

How much further than its receiving surfaces an overlay projects, and how much wider than their angle to the projection it accepts faces, this gives some leeway to account for imprecision.

public const float ProjectionMargin = 8

Field Value

float

Methods

FromProjectedGeometry(ReadOnlySpan<Vector3>, ReadOnlySpan<Vector2>, ReadOnlySpan<int>, string, Func<string, Vector2?>?)

Rebuilds the overlays a compiled overlay mesh came from, the geometry is welded and split into connected pieces first using .

public static List<CMapStaticOverlay> FromProjectedGeometry(ReadOnlySpan<Vector3> positions, ReadOnlySpan<Vector2> texCoords, ReadOnlySpan<int> triangles, string material, Func<string, Vector2?>? textureSizeProvider = null)

Parameters

positions ReadOnlySpan<Vector3>

texCoords ReadOnlySpan<Vector2>

triangles ReadOnlySpan<int>

material string

textureSizeProvider Func<string, Vector2?>?

Returns

List<CMapStaticOverlay>

FromProjectedMesh(PolygonMesh, string, Func<string, Vector2?>?)

Rebuilds an overlay from a .

public static CMapStaticOverlay? FromProjectedMesh(PolygonMesh projected, string material, Func<string, Vector2?>? textureSizeProvider = null)

Parameters

projected PolygonMesh

material string

textureSizeProvider Func<string, Vector2?>?

Returns

CMapStaticOverlay?

FromProjectedMesh(ReadOnlySpan<Vector3>, ReadOnlySpan<Vector2>, ReadOnlySpan<int>, string, Func<string, Vector2?>?)

Rebuilds an overlay from its projected triangles, this should only be fed singular connected mesh islands.

public static CMapStaticOverlay? FromProjectedMesh(ReadOnlySpan<Vector3> positions, ReadOnlySpan<Vector2> texCoords, ReadOnlySpan<int> triangles, string material, Func<string, Vector2?>? textureSizeProvider = null)

Parameters

positions ReadOnlySpan<Vector3>

texCoords ReadOnlySpan<Vector2>

triangles ReadOnlySpan<int>

material string

textureSizeProvider Func<string, Vector2?>?

Returns

CMapStaticOverlay?

RemoveStackedDuplicates(ReadOnlySpan<Vector3>, ReadOnlySpan<Vector2>, ReadOnlySpan<int>)

Flags projected triangles that duplicate the same decal region on a surface stacked behind another. The compiler clips a decal against every surface its projection reaches, so a surface hidden behind another carries a second copy that would come back as duplicated faces stacked on the rebuilt overlay. Returns one flag per triangle, set when the triangle is such a duplicate and should be left out.

public static bool[] RemoveStackedDuplicates(ReadOnlySpan<Vector3> positions, ReadOnlySpan<Vector2> texCoords, ReadOnlySpan<int> triangles)

Parameters

positions ReadOnlySpan<Vector3>

texCoords ReadOnlySpan<Vector2>

triangles ReadOnlySpan<int>

Returns

bool[]
