class TerrainVisibleCheck in Tinman.Terrain.Visibility

The TerrainVisibleCheck is the default implementation of the IVisibleCheck interface for terrain-space visible checks.

sealed class

TerrainVisibleCheck

extends

DefaultVisibleCheck

Remarks

Use this class for generating static meshes (collision meshes, for example).

Public / Methods

Add

Adds the given visibility check to this one, so that a mesh vertex will be visible if at least one of both returns true.

[Pure]
public virtual method	Add (IVisibleCheck check)
type	IVisibleCheck
params	check	[not-null]	The visibility check to add.
returns		[not-null]	The resulting visibility check.
inherited	VisibleCheck.Add

See also:

IVisibleCheck.Remove

Contains

Does this visible check contain the given one?

[Pure]
public virtual method	Contains (IVisibleCheck check)
type	bool
params	check	[not-null]	The visible check.
returns			true if check is contained, i.e. calling Add will return this. false if check is not contained, i.e. calling Remove will return this.
inherited	VisibleCheck.Contains

IsVertexVisible

Computes whether the given vertex shall be visible in the terrain mesh or not.

[Pure]
public override method	IsVertexVisible (int32 v, int32 g, int32 a, float64 thresholdSqr)
type	bool
params	v		The vertex to check for visibility.
	g		Grand-parent of v.
	a		Ancestor vertex of v.
	thresholdSqr		The tolerated squared terrain-space vertex error.
returns			true if the squared terrain-space vertex error value is greater than thresholdSqr (i.e. the vertex will be visible in the terrain mesh), false if not (i.e. the vertex will be invisible).
implements	VisibleCheck.IsVertexVisible

Remarks:

This method will be called repeatedly only by the refinement thread of the MeshBuffer. Thus, as long as no other code is called it, thread-safe code is not required here.

Remove

Removes the given vertex visibility check from this one, so that a mesh vertex will only be visible if this one returns true.

[Pure]
public virtual method	Remove (IVisibleCheck check)
type	IVisibleCheck
params	check	[not-null]	The visibility check to remove.
returns		[not-null]	The resulting visibility check.
inherited	VisibleCheck.Remove

IVisibleCheck.Add

SetVertexArrays

Sets the vertex data containers from which this vertex converter shall read vertex data.

public override method	SetVertexArrays (VertexArrays vertexArrays)
params	vertexArrays	[not-null]	The vertex data collection.
inherited	DefaultVisibleCheck.SetVertexArrays

ToString

[Pure]
public override method	ToString ()
type	string
overrides	DefaultVisibleCheck.ToString
