.PP
The ElevationGrid node specifies a uniform rectangular grid of varying height in the Y=0 plane of the local coordinate system\&. The geometry is described by a scalar array of height values that specify the height of a surface above each point of the grid\&.

.PP
The xDimension and zDimension fields indicate the number of elements of the grid height array in the X and Z directions\&. Both xDimension and zDimension shall be greater than or equal to zero\&. If either the xDimension or the zDimension is less than two, the ElevationGrid contains no quadrilaterals\&. The vertex locations for the rectangles are defined by the height field and the xSpacing and zSpacing fields:

.PP
.PD 0
.IP "\(bu" 1
The height field is an xDimension by zDimension array of scalar values representing the height above the grid for each vertex\&.
.PP
.PD 0
.IP "\(bu" 1
The xSpacing and zSpacing fields indicate the distance between vertices in the X and Z directions respectively, and shall be greater than zero\&.
.PP
Thus, the vertex corresponding to the point P[i, j] on the grid is placed at:

.PP
.PP
.nf
  P[i,j]\&.x = xSpacing × i
  P[i,j]\&.y = height[ i + j × xDimension]
  P[i,j]\&.z = zSpacing × j     

  where 0 <= i < xDimension and 0 <= j < zDimension, and 
  P[0,0] is height[0] units above/below the origin of the local
  coordinate system
.fi
.PP

.PP
The set_height eventIn allows the height MFFloat field to be changed to support animated ElevationGrid nodes\&. 
.br

.PP
The color field specifies per-vertex or per-quadrilateral colours for the ElevationGrid node depending on the value of colorPerVertex\&. If the color field is NULL, the ElevationGrid node is rendered with the overall attributes of the Shape node enclosing the ElevationGrid node (see 4\&.14, Lighting model)\&. 
.br

.PP
The colorPerVertex field determines whether colours specified in the color field are applied to each vertex or each quadrilateral of the ElevationGrid node\&. If colorPerVertex is FALSE and the color field is not NULL, the color field shall specify a Color node containing at least (xDimension-1)×(zDimension-1) colours; one for each quadrilateral, ordered as follows:

.PP
.PP
.nf
  QuadColor[i,j] = Color[ i + j × (xDimension-1)]

  where 0 <= i < xDimension-1 and 0 <= j < zDimension-1, and
  QuadColor[i,j] is the colour for the quadrilateral defined by
  height[i+j×xDimension], height[(i+1)+j×xDimension],
  height[(i+1)+(j+1)×xDimension] and height[i+(j+1)×xDimension] 
.fi
.PP

.PP
If colorPerVertex is TRUE and the color field is not NULL, the color field shall specify a Color node containing at least xDimension × zDimension colours, one for each vertex, ordered as follows:

.PP
.PP
.nf
  VertexColor[i,j] = Color[ i + j × xDimension] 

  where 0 <= i < xDimension and 0 <= j < zDimension, and 
  VertexColor[i,j] is the colour for the vertex defined by 
  height[i+j×xDimension] 
.fi
.PP

.PP
The normal field specifies per-vertex or per-quadrilateral normals for the ElevationGrid node\&. If the normal field is NULL, the browser shall automatically generate normals, using the creaseAngle field to determine if and how normals are smoothed across the surface (see 4\&.6\&.3\&.5, Crease angle field)\&.

.PP
The normalPerVertex field determines whether normals are applied to each vertex or each quadrilateral of the ElevationGrid node depending on the value of normalPerVertex\&. If normalPerVertex is FALSE and the normal node is not NULL, the normal field shall specify a Normal node containing at least (xDimension-1)×(zDimension-1) normals; one for each quadrilateral, ordered as follows:

.PP
.PP
.nf
  QuadNormal[i,j] = Normal[ i + j × (xDimension-1)] 

  where 0 <= i < xDimension-1 and 0 <= j < zDimension-1, and 
  QuadNormal[i,j] is the normal for the quadrilateral 
  defined by height[i+j×xDimension], height[(i+1)+j×xDimension], 
  height[(i+1)+(j+1)×xDimension] and height[i+(j+1)×xDimension] 
.fi
.PP

.PP
If normalPerVertex is TRUE and the normal field is not NULL, the normal field shall specify a Normal node containing at least xDimension × zDimension normals; one for each vertex, ordered as follows:

.PP
.PP
.nf
  VertexNormal[i,j] = Normal[ i + j × xDimension] 
  
  where 0 <= i < xDimension and 0 <= j < zDimension, and
  VertexNormal[i,j] is the normal for the vertex defined by
  height[i+j×xDimension] 
.fi
.PP

.PP
The texCoord field specifies per-vertex texture coordinates for the ElevationGrid node\&. If texCoord is NULL, default texture coordinates are applied to the geometry\&. The default texture coordinates range from (0,0) at the first vertex to (1,1) at the last vertex\&. The S texture coordinate is aligned with the positive X-axis, and the T texture coordinate with positive Z-axis\&. If texCoord is not NULL, it shall specify a TextureCoordinate node containing at least (xDimension)×(zDimension) texture coordinates; one for each vertex, ordered as follows:

.PP
.PP
.nf
  VertexTexCoord[i,j] = TextureCoordinate[ i + j × xDimension] 

  where 0 <= i < xDimension and 0 <= j < zDimension, and 
  VertexTexCoord[i,j] is the texture coordinate for the vertex 
  defined by height[i+j×xDimension] 
.fi
.PP

.PP
The ccw, solid, and creaseAngle fields are described in 4\&.6\&.3, Shapes and geometry\&. By default, the quadrilaterals are defined with a counterclockwise ordering\&. Hence, the Y-component of the normal is positive\&. Setting the ccw field to FALSE reverses the normal direction\&. Backface culling is enabled when the solid field is TRUE\&. See Figure 6\&.5 for a depiction of the ElevationGrid node\&.
