direct3d 9 sdk has a example like below; CUSTOMVERTEX g_Vertices[] = { { -1.0f,-1.0f, 0.0f }, { 1.0f,-1.0f, 0.0f}, { 0.0f, 1.0f, 0.0f }, }; another book is CUSTOMVERTEX g_Vertices[] = { { -100.0f, 100.0f, 0.0f}, { 100.0f, 100.0f, 0.0f}, { -100.0f, -100.0f, 0.0f}, the question is how to define the accurately Vertices location.

Doesn't the declaration already contain information about its position? At least the second array appears to have a position and texture coordinates (unless the first three are unnormalized normals) in an array format.

How is CUSTOMVERTEX defined?

Both are as accurate as floating point numbers can be.
The difference is probably in the view matrix.
