Syntax

Copy

public class HeightMapSurfaceNode : ModelNode

The HeightMapSurfaceNode type exposes the following members.

Constructors

	Name	Description
	HeightMapSurfaceNode(String)	Initializes a new instance of the HeightMapSurfaceNode class
	HeightMapSurfaceNode(Vector3, Vector3, Single, Boolean, Single, Single, String)	Initializes a new instance of the HeightMapSurfaceNode class

Properties

	Name	Description
	CenterPosition	Center position of the height map surface Default value is (0, 0, 0).
	HeightData	2D array defining the height data. The dimensions of array also determine the size of the mesh (scaled by the X and Z components of the Size property). If no height data is provided, a flat surface (a plane) is generated. Default value is null (no height data available).
	HeightDataMaxValue	Gets the maximum value from the HeightData array.
	HeightDataMinValue	Gets the minimum value from the HeightData array.
	MaxTextureHeight	Used to define custom height range for texture coordinates. Applicable only if UseHeightValuesAsTextureCoordinates is set to true. Default value is Single.NaN (disabled).
	MinTextureHeight	Used to define custom height range for texture coordinates. Applicable only if UseHeightValuesAsTextureCoordinates is set to true. Default value is Single.NaN (disabled).
	Size	Size of the surface. X and Z components scale the 2D shape's width and height, while Y component scales the height values. Default value is (1, 1, 1)
	UseHeightValuesAsTextureCoordinates	Use height values to generate texture coordinates. If disabled, texture coordinates are generated so that the texture is aligned with the dimensions of the surface. If enabled, texture coordinates are based on height value, which is useful for gradient-based textures. Default value is false.

Methods

	Name	Description
	CreateHeightDataFromImageData	CreateHeightDataFromImageData method creates a two dimensional array from the specified imageData that can be used for the HeightData property. The supported image formats are R8G8B8A8Unorm, B8G8R8A8Unorm (32 bit where height value is average value of red, green and blue color values) and R8Unorm (8 bit grayscale).
	CreateHeightMapSurfaceMesh
	OnUpdate	(Overrides ModelNodeOnUpdate)
	UpdateMesh	UpdateMesh method recreates the mesh based on the current object properties. The method should be overriden in the derived class that provides its own mesh generation. (Overrides ModelNodeUpdateMesh)
