Struct SkyTransform

Namespace: ValveResourceFormat.Renderer.World
Assembly: Renderer.dll

Maps between world space and the sky space of a 3D sky.

public readonly record struct SkyTransform : IEquatable<SkyTransform>

Implements

IEquatable<SkyTransform>

Remarks

The sky geometry is never scaled; the sky_camera scale only moves the camera, so

world units are one sky unit.

Constructors

SkyTransform(Vector3, Vector3, float)

Initializes a new instance of the struct.

public SkyTransform(Vector3 reference, Vector3 origin, float scale)

Parameters

reference Vector3

origin Vector3

scale float

Properties

FogSpace

Gets the conversion of fog authored in world units into sky space.

public FogSpace FogSpace { get; }

Property Value

FogSpace

Origin

Gets the sky_camera position in sky space.

public Vector3 Origin { get; }

Property Value

Vector3

Reference

Gets the skybox_reference position in world space, which lines up with .

public Vector3 Reference { get; }

Property Value

Vector3

Scale

Gets how many world units one sky unit stands for. Always positive.

public float Scale { get; }

Property Value

float

SkyToWorld

Gets the transform from sky space to world space.

public Matrix4x4 SkyToWorld { get; }

Property Value

Matrix4x4

Methods

ConfigureCamera(Camera, Camera)

Sets camera up to view the sky from the sky space position matching from.

public void ConfigureCamera(Camera camera, Camera from)

Parameters

camera Camera

from Camera

Remarks

Clip planes are divided by the scale too, so sky depth matches a sky scaled up to world size.

FromEntities(Vector3, SkyCamera?)

Creates the transform from entity positions only, so neither entity rotates the view. Without a sky_camera the sky is seen from its origin at 1:1.

public static SkyTransform FromEntities(Vector3 reference, SkyCamera? skyCamera)

Parameters

reference Vector3

skyCamera SkyCamera?

Returns

SkyTransform

ToSky(Vector3)

Maps a world position to sky space.

public Vector3 ToSky(Vector3 worldPosition)

Parameters

worldPosition Vector3

Returns

Vector3

ToWorld(Vector3)

Maps a sky space position to world space.

public Vector3 ToWorld(Vector3 skyPosition)

Parameters

skyPosition Vector3

Returns

Vector3
