Constants

D3DDECLTYPE_FLOAT1

One-component float expanded to (float, 0, 0, 1).

D3DDECLTYPE_FLOAT2

Two-component float expanded to (float, float, 0, 1).

D3DDECLTYPE_FLOAT3

Three-component float expanded to (float, float, float, 1).

D3DDECLTYPE_FLOAT4

Four-component float expanded to (float, float, float, float).

D3DDECLTYPE_D3DCOLOR

Four-component, packed, unsigned bytes mapped to 0 to 1 range. Input is a D3DCOLOR and is expanded to RGBA order.

D3DDECLTYPE_UBYTE4

Four-component, unsigned byte.

D3DDECLTYPE_SHORT2

Two-component, signed short expanded to (value, value, 0, 1).

D3DDECLTYPE_SHORT4

Four-component, signed short expanded to (value, value, value, value).

D3DDECLTYPE_UBYTE4N

Four-component byte with each byte normalized by dividing with 255.0f.

D3DDECLTYPE_SHORT2N

Normalized, two-component, signed short, expanded to (first short/32767.0, second short/32767.0, 0, 1).

D3DDECLTYPE_SHORT4N

Normalized, four-component, signed short, expanded to (first short/32767.0, second short/32767.0, third short/32767.0, fourth short/32767.0).

D3DDECLTYPE_USHORT2N

Normalized, two-component, unsigned short, expanded to (first short/65535.0, short short/65535.0, 0, 1).

D3DDECLTYPE_USHORT4N

Normalized, four-component, unsigned short, expanded to (first short/65535.0, second short/65535.0, third short/65535.0, fourth short/65535.0).

D3DDECLTYPE_UDEC3

Three-component, unsigned, 10 10 10 format expanded to (value, value, value, 1).

D3DDECLTYPE_DEC3N

Three-component, signed, 10 10 10 format normalized and expanded to (v[0]/511.0, v[1]/511.0, v[2]/511.0, 1).

D3DDECLTYPE_FLOAT16_2

Two-component, 16-bit, floating point expanded to (value, value, 0, 1).

D3DDECLTYPE_FLOAT16_4

Four-component, 16-bit, floating point expanded to (value, value, value, value).

D3DDECLTYPE_UNUSED

Type field in the declaration is unused. This is designed for use with D3DDECLMETHOD_UV and D3DDECLMETHOD_LOOKUPPRESAMPLED.

Remarks

Vertex data is declared with an array of D3DVERTEXELEMENT9 structures. Each element in the array contains a vertex declaration data type.

Use the DirectX Caps Viewer Tool tool to see which types are supported on your device.
