is there any way I can shorten this array.I am using dx9 and c++.
[font="Consolas"][font="Consolas"]CUSTOMVERTEX vertices[] =

{

{ 0.0f, 0.0f, 0.5f, 1.0f, D3DCOLOR_XRGB(255, 0, 0), },

When you say "shorten", what exactly do you mean? The size of the declaration in your code, or do you mean to reduce the memory footprint of the array?

Although its pointless, as in a real application you always store such data offline and not in the code:

- Erase all .0f's, no need for them here
- Cache your D3DCOLOR_XRGBs in D3DCOLOR variables

No need to use a FLOAT4 if your w is always 1. Use FLOAT3, it will get that one automatically. Since this looks 2D even FLOAT2 could work. Reduces memory footprint, too.
