Render effect parameters for ITerrainEffect.

The following low-level render effect parameter slots are always defined:

Flag​Emulating

public constant FlagEmulating → (1:int32)

Specifies that a non Direct3D 9 graphics context is emulating the TerrainFeatureLevel.DX9 feature level (for example OpenGL).

When this flag is used, use of texture arrays will be enabled and the count of materials per pass will be 4.

Pass​Color

public constant PassColor → (0:int32)

Render effect pass: vertex color shading.

Pass​Decal

public constant PassDecal → (1:int32)

Render effect pass: terrain decal overlay.

Pass​Highlight

public constant PassHighlight → (2:int32)

Render effect pass: simple highlighting with alpha blending.

Pass​Material

public constant PassMaterial → (3:int32)

Render effect pass: material based terrain texturing.

Render effect pass: shadow map.

Pass​Texture​Atlas

public constant PassTextureAtlas → (6:int32)

Render effect pass: unique texturing with texture pyramids via TextureAtlas.

Pass​Texture​Dome

public constant PassTextureDome → (7:int32)

Render effect pass: unique texturing of background dome via TextureAtlas.

Pass​Wireframe

public constant PassWireframe → (8:int32)

Render effect pass: terrain wireframe overlay.

Public / Constructors

Terrain​Parameters

public constructor TerrainParameters → (1)

featureLevel in : TerrainFeatureLevel

Creates a new instance of TerrainParameters.

Public / Methods

Compute​Vertex​Blend

public method ComputeVertexBlend → (2)

viewport in : Viewport

[not-null]
The viewport.

mesh in : IMeshDynamic

[not-null]

Create​Effect

[OwnerReturn]
public static method CreateEffect → (3)

context in : IGraphicsContext

[not-null]
The graphics context to use.

featureLevelMin opt : TerrainFeatureLevel = TerrainFeatureLevel.DX9

The minimum feature level (inclusive).

featureLevelMax opt : TerrainFeatureLevel = TerrainFeatureLevel.DX12

The maximum feature level (inclusive).

returns → ITerrainEffect

The resulting ITerrainEffect or null iff no feature level is applicable to the given graphics context in.

Tries to create a ITerrainEffect with the highest feature level between featureLevelMin opt and featureLevelMax opt.

RenderException

If a graphics subsystem error has occurred.

Feature​Level​Max

public static method FeatureLevelMax → (1)

context in : IGraphicsContext

The graphics context.

returns → TerrainFeatureLevel

The maximum feature level.

Determines the maximum TerrainFeatureLevel that is supported by the given graphics context in.

Feature​Level​Min

public static method FeatureLevelMin → (1)

context in : IGraphicsContext

The graphics context.

returns → TerrainFeatureLevel

The maximum feature level.

Determines the minimum TerrainFeatureLevel that is supported by the given graphics context in.

Public / Attributes

Camera

public readonly attribute Camera → (CameraParameters)

The aggregated camera parameters.

See also

TerrainParameters.ChangedCamera

Decal

public readonly attribute Decal → (DecalParameters)

The aggregated decal parameters.

See also

TerrainParameters.ChangedDecal

Feature​Level

public attribute FeatureLevel → (get)

value : TerrainFeatureLevel

The feature level.

The GPU feature level.

Highlight

public attribute Highlight → (get,set)

value : int64

The color value, see Colors.

Custom color value to blend the terrain to (used for highlighting mesh sectors).

Defaults to 0.

TerrainParameters.ChangedHighlight

Layer​Blend

public attribute LayerBlend → (get,set)

value : Fade

The fade range.

Fade range to use for blending terrain layers.

Defaults to Fade.AlwaysZero.

TerrainParameters.ChangedLayerBlend

Lighting

public readonly attribute Lighting → (LightingParameters)

The aggregated lighting parameters.

See also

TerrainParameters.ChangedLighting

Material

public readonly attribute Material → (TerrainMaterialParameters)

The aggregated material parameters.

See also

TerrainParameters.ChangedMaterial

Mesh

public readonly attribute Mesh → (MeshParameters)

The aggregated mesh parameters.

See also

TerrainParameters.ChangedMesh

Shadow

public readonly attribute Shadow → (ShadowParameters)

The aggregated shadow parameters.

See also

TerrainParameters.ChangedShadow

Texture

public readonly attribute Texture → (TerrainTextureParameters)

See also

TerrainParameters.ChangedTexture

Vertex​Blend

public attribute VertexBlend → (get,set)

value : Vec4F

The coefficient vector.

Coefficients to use for blending vertex data between LOD levels:

x := screenSpace / terrainSpace * cameraDistance
y := x * x
z := qualityThresholdInScreenSpace
w := log2(pi * z * z)

x may be obtained by passing (1, 1) to Viewport.Project.
z may be obtained by getting IMeshDynamic.QualityThreshold.
w is the screen-space area of circle with radius z.

Set to (0,0,-1,-1) to use maximum LOD everywhere.

Defaults to Vec4F.Zero.
