vertex buffer value ?

No, the SetTransform sets the transform of the device. Your vertex buffer is untouched. You could sa that origo in the world is moved.
Instead of listening to me, read the DirectX Documents :-)


I am a signature virus. Please add me to your signature so that I may multiply.

there is something i can not figure out.

Does the SetTransform function actually change the values in the vertexbuffer ?

for example : SetTransform( D3DTS_WORLD, &m_worldMatrix );

or the values in the vertexbuffer stay constant

thanks for your help...

your vertex buffer remain the same, it is just that when direcx read the data from the vertex buffer it automatically add to each vertex the current transformation from D3DTS_WORLD.

That is very usefull for draw somthing in just one position, and then been able to move or rotate the model to different position and orientation with not need to make any changes in your data.
