void setSkirtHeight(float skirtHeight)

Set the height of the skirt to render around the edge of HeightField. The skirt is used as a means of disguising edge boundaries between adjacent HeightField, particular of ones with different resolutions.

float getSkirtHeight() const

Get the height of the skirt to render around the edge of HeightField

void setBorderWidth(unsigned int borderWidth)

Set the width in number of cells in from the edge that the height field should be rendered from. This exists to allow gradient and curvature continutity to be maintained between adjacent HeightField, where the border cells will overlap adjacent HeightField.

unsigned int getBorderWidth() const

Get the width in number of cells in from the edge that the height field should be rendered from
