The buffer to read from.

Returns

short[]

Remarks

Warning! No check is performed to ensure the buffer actually uses 16-bit values.

Read32Bit(IndexBuffer)

Copies the content of an SlimDX.Direct3D9.IndexBuffer to an array of 32-bit values.

public static int[] Read32Bit(this IndexBuffer buffer)

Parameters

buffer IndexBuffer

The buffer to read from.

Returns

int[]

Remarks

Warning! No check is performed to ensure the buffer actually uses 32-bit values.

Copies the content of the attribute buffer of a SlimDX.Direct3D9.Mesh to an array of 32-bit values.

public static int[] ReadAttributeBuffer(this Mesh mesh)

Parameters

mesh Mesh

The SlimDX.Direct3D9.Mesh containing the buffer to read from.

Returns

int[]

ReadIndexBuffer(Mesh)

Copies the content of the SlimDX.Direct3D9.IndexBuffer of a SlimDX.Direct3D9.Mesh to an array of 32-bit values (16-bit values are automatically converted).

public static int[] ReadIndexBuffer(this Mesh mesh)

Parameters

The SlimDX.Direct3D9.Mesh containing the buffer to read from.

Returns

int[]

ReadVertexBuffer<T>(Mesh)

Copies the content of the SlimDX.Direct3D9.VertexBuffer of a SlimDX.Direct3D9.Mesh to an array of structs.

Parameters

mesh Mesh

The SlimDX.Direct3D9.Mesh containing the buffer to read from.

Returns

T[]

The content of the buffer in mesh.

Type Parameters

T

The vertex format used in the buffer.

Read<T>(VertexBuffer)

Copies the content of a SlimDX.Direct3D9.VertexBuffer to an array of structs.

public static T[] Read<T>(this VertexBuffer buffer) where T : struct

Parameters

buffer VertexBuffer

The buffer to read from.

Returns

ToDefaultPool(Mesh, bool)

Creates a copy of a SlimDX.Direct3D9.Mesh in SlimDX.Direct3D9.Pool.Default, ready for rendering.

public static Mesh ToDefaultPool(this Mesh mesh, bool writeOnly = true)

Parameters

mesh Mesh

The finished system memory mesh to publish.

writeOnly bool

Add SlimDX.Direct3D9.MeshFlags.WriteOnly for the fastest possible rendering. Prevents any CPU read-back.

Returns

Mesh

public static MeshFlags ToDefaultPool(this MeshFlags options)

Parameters

options MeshFlags

Returns

MeshFlags

Remarks

All other flags, most importantly SlimDX.Direct3D9.MeshFlags.Use32Bit, are preserved.
