Syntax

public class MeshToSDFBaker : IDisposable

Constructors

MeshToSDFBaker(Vector3, Vector3, int, List<Mesh>, List<Matrix4x4>, int, float, float, CommandBuffer)

Constructor of the class MeshToSDFBaker.

Declaration

public MeshToSDFBaker(Vector3 sizeBox, Vector3 center, int maxRes, List<Mesh> meshes, List<Matrix4x4> transforms, int signPassesCount = 1, float threshold = 0.5, float sdfOffset = 0, CommandBuffer cmd = null)

Parameters

Type	Name	Description
Vector3	sizeBox	The desired size of the baking box
Vector3	center	The center of the baking box.
int	maxRes	The resolution along the largest dimension.
List<Mesh>	meshes	The list of meshes to be baked into an SDF.
List<Matrix4x4>	transforms	The list of transforms of the meshes.
int	signPassesCount	The number of refinement passes on the sign of the SDF. This should stay below 20.
float	threshold	The threshold controlling which voxels will be considered inside or outside of the surface.
float	sdfOffset	The Offset to add to the SDF. It can be used to make the SDF more bulky or skinny.
CommandBuffer	cmd	The CommandBuffer on which the baking process will be added.

Properties

SdfTexture

Returns the texture containing the baked Signed Distance Field

Declaration

public RenderTexture SdfTexture { get; }

Property Value

Type	Description
RenderTexture

Methods

BakeSDF()

Performs the baking operation. After this function is called, the resulting SDF is accessible via the property MeshToSDFBaker.SdfTexture.

Declaration

public void BakeSDF()

Dispose()

Release all the buffers and textures created by the object. This must be called you are finished using the object.

Declaration

public void Dispose()

~MeshToSDFBaker()

This finalizer should never be called. Dispose() should be called explicitly when an MeshToSDFBaker instance is finished being used.

Declaration

protected ~MeshToSDFBaker()

GetActualBoxSize()

Gets the size of the baking box used.

Declaration

public Vector3 GetActualBoxSize()

Returns

Type	Description
Vector3	A Vector3 containing the size of the box along the three directions of space

GetGridSize()

Gets the dimensions of the baked texture.

Declaration

public Vector3Int GetGridSize()

Returns

Type	Description
Vector3Int	A Vector3Int containing the height, width and depth of the texture.

Reinit(Vector3, Vector3, int, List<Mesh>, List<Matrix4x4>, int, float, float)
