SurfaceUtils Class

Tools for working Surfaces on Interactables.

Static Methods

ComputeDepth ( surfacePatch , point , radius )
The distance below a surface along the closest normal.
always positive.
Signature 
static float ComputeDepth(ISurfacePatch surfacePatch, Vector3 point, float radius)
Parameters
surfacePatch: ISurfacePatch
point: Vector3  the origin point to compute distance from the surface
radius: float  the radius of the sphere positioned at the origin point
Returns
float
ComputeDistanceAbove ( surfacePatch , point , radius )
The distance above a surface along the closest normal.
Returns 0 for where the sphere touches the surface along the normal.
Signature 
static float ComputeDistanceAbove(ISurfacePatch surfacePatch, Vector3 point, float radius)
Parameters
surfacePatch: ISurfacePatch
point: Vector3  The origin point to compute distance from the surface
radius: float  The radius of the sphere positioned at the origin point
Returns
float
ComputeDistanceFrom ( surfacePatch , point , radius )
The distance from the closest point as computed by the proximity field and surface.
Returns the distance to the point without taking into account the surface normal.
Signature 
static float ComputeDistanceFrom(ISurfacePatch surfacePatch, Vector3 point, float radius)
Parameters
surfacePatch: ISurfacePatch
point: Vector3  the origin point to compute distance from the surface
radius: float  the radius of the sphere positioned at the origin point
Returns
float
ComputeTangentDistance ( surfacePatch , point , radius )
The distance to a surface along the tangent.
Signature 
static float ComputeTangentDistance(ISurfacePatch surfacePatch, Vector3 point, float radius)
Parameters
surfacePatch: ISurfacePatch
point: Vector3  The origin point to compute distance from the surface
radius: float  The radius of the sphere positioned at the origin point
Returns
float
