Members

• sx
  Values describing a vertex in screen coordinates.
• dvSX
  Values describing a vertex in screen coordinates.
• sy
  Values describing a vertex in screen coordinates.
• dvSY
  Values describing a vertex in screen coordinates.
• sz
  Values describing a vertex in screen coordinates.
• dvSZ
  Values describing a vertex in screen coordinates. The largest allowable value for dvSZ is 1.0 if you want the vertex to be within the range of z-values that are displayed.
• rhw
  Value that is the reciprocal of homogeneous w from homogeneous coordinates (x, y, z, w). This value is often 1 divided by the distance from the origin to the object along the z-axis.
• dvRHW
  Value that is the reciprocal of homogeneous w from homogeneous coordinates (x, y, z, w). This value is often 1 divided by the distance from the origin to the object along the z-axis.
• color
  Values describing the color component of the vertex.
• dcColor
  Values describing the color component of the vertex.
• specular
  Values describing the specular component of the vertex.
• dcSpecular
  Values describing the specular component of the vertex.
• tu
  Values describing the texture coordinates of the vertex.
• dvTU
  Values describing the texture coordinates of the vertex.
• tv
  Values describing the texture coordinates of the vertex.
• dvTV
  Values describing the texture coordinates of the vertex.

Remarks

Direct3D uses the current viewport parameters, which are the x, y, Width, and Height members of the D3DVIEWPORT8 type to clip D3DTLVERTEX vertices. The system always clips z-coordinates to (0, 1).

If D3DRS_SPECULARENABLE is 1, the specular component will be added to the base color after the texture cascade but before alpha blending. However, you can assign the specular component to be applied during texture color processing by setting the D3DTA_SPECULAR flag. For more information, see Texture Argument Flags.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: D3dtypes.h.
