Struct UnsafeVertexData

An managed, resizable vertex data, without any thread safety check features. Stores generic vertex information in interleaved array. As example if structure is created with Position+Normal attributes as result data will be stored in memory as follows: position0/normal0/position1/normal1...

Capacity

The number of elements that fit in the current allocation.

Declaration

public int Capacity { get; }

Property Value

Type	Description
System.Int32	The number of elements that fit in the current allocation.

Exceptions

Type	Condition

IsCreated

Whether this the vertex data has been allocated (and not yet deallocated).

Declaration

public bool IsCreated { get; }

Property Value

Type	Description
System.Boolean	True if this the vertex data has been allocated (and not yet deallocated).

| Improve this Doc View Source

IsEmpty

Whether the vertex data is empty.

Declaration

public bool IsEmpty { get; }

Property Value

Type	Description
System.Boolean	True if the list is empty or the list has not been constructed.

Length

The count of elements.

Declaration

public int Length { get; }

Property Value

Type	Description
System.Int32	The current count of elements. Always less than or equal to the capacity.

Remarks

To decrease the memory used by a list, set Capacity after reducing the length of the list.

Size

Size of the single vertex. It is a sum of all attributes size.

Declaration

public int Size { get; }

Property Value

Type	Description
System.Int32

Methods

Create(Int32, NativeArray<VertexAttributeDescriptor>, AllocatorManager.AllocatorHandle)

Creates a new container with the specified initial capacity and type of memory allocation.

Declaration
