Constants describing the vertex data types supported by a device.

#define Value Description
D3DDTCAPS_UBYTE4 0x00000001L 4D unsigned byte.
D3DDTCAPS_UBYTE4N 0x00000002L Normalized, 4D unsigned byte. Each of the four bytes is normalized by dividing to 255.0.
D3DDTCAPS_SHORT2N 0x00000004L Normalized, 2D signed short, expanded to (first byte/32767.0, second byte/32767.0, 0, 1).
D3DDTCAPS_SHORT4N 0x00000008L Normalized, 4D signed short, expanded to (first byte/32767.0, second byte/32767.0, third byte/32767.0, fourth byte/32767.0).
D3DDTCAPS_USHORT2N 0x00000010L Normalized, 2D unsigned short, expanded to (first byte/65535.0, second byte/65535.0, 0, 1).
D3DDTCAPS_USHORT4N 0x00000020L Normalized 4D unsigned short, expanded to (first byte/65535.0, second byte/65535.0, third byte/65535.0, fourth byte/65535.0).
D3DDTCAPS_UDEC3 0x00000040L 3D unsigned 10 10 10 format expanded to (value, value, value, 1).
D3DDTCAPS_DEC3N 0x00000080L 3D signed 10 10 10 format normalized and expanded to (v[0]/511.0, v[1]/511.0, v[2]/511.0, 1).
D3DDTCAPS_FLOAT16_2 0x00000100L 2D 16-bit floating point numbers.
D3DDTCAPS_FLOAT16_4 0x00000200L 4D 16-bit floating point numbers.
