Lighting problem

Greeting, gentlemen. I use directional light and everything's ok, but once i tried changing it either to point or spot it just does nothing. Before that, i changed the position: 

D3DXMATRIX g_Transform;
D3DXMatrixIdentity(&g_Transform);
D3DXMatrixTranslation(&g_Transform,-150.0f, -150.0f, -100.0f);	
g_pd3dDevice->SetTransform(D3DTS_WORLD, &g_Transform);
And my material: 

ZeroMemory(&g_Material, sizeof(D3DMATERIAL9));
g_Material.Diffuse.r = 1.0f;
g_Material.Diffuse.g = 1.0f;
g_Material.Diffuse.b = 1.0f;
g_pd3dDevice->SetMaterial(&g_Material);
Here's one light i tried 

ZeroMemory( &light, sizeof(D3DLIGHT9) );
light.Type       = D3DLIGHT_SPOT;
light.Diffuse.r  = 1.0f;
light.Diffuse.g  = 1.0f;
light.Diffuse.b  = 1.0f;
light.Position = D3DXVECTOR3(-150.0f, 150.0f, 100.0f);
light.Theta = D3DX_PI/4.0f; light.Phi = D3DX_PI/2.0f;
vecDir = D3DXVECTOR3(0.0f,0.0f,0.0f);
D3DXVec3Normalize( (D3DXVECTOR3*)&light.Direction, &vecDir );
light.Range       = 1000.0f;
g_pd3dDevice->SetLight( 0, &light );
g_pd3dDevice->LightEnable( 0, TRUE );
The questions are: 1. How do i give the coordinates - do i assume that the world center is set in (150, 150, 100) or (0,0,0)? 2. What's wrong with the light?

how is a normalized 0-vector supposed to look? What I mean is in your code snippet for the light you have
vecDir = D3DXVECTOR3(0.0f,0.0f,0.0f);D3DXVec3Normalize( (D3DXVECTOR3*)&light.Direction, &vecDir );

Essentially you´re trying to normalize a vector that has a length of 0, which is not going to work. So after all you should end up with a light.Direction of (0.0f, 0.0f, 0.0f), which should render the spot useless. Try some simple values for the direction (like (1.f, 0.f, 0.f), (0.f, 1.f, 0.f) and so on)... Perhaps that fixes both your problems because you might see whether the light is in the correct position or not.

One other thing - it doesn't look like you're configuring the 'attenuation' for your light source. I'm pretty sure 0-values for those 3 fields will cancel out any contribution of a spot/omni light.

You might find the Light Attenuation section of the Light Properties documentation useful.

light.Attenuation0 = 0.0f;
light.Attenuation1 = 1.0f;
light.Attenuation2 = 0.0f;

might be worth trying [smile]

Well, it doesn't help. I mean, the directional is still here but the rest...
It's not with the normals, but it's weird. What do you set for spotlight which you don't set for directional?

Try att0 = 1, att1 = 0, att2 = 0
and change light type to POINT just to see that it works.

Also, what is your direction for the spot light ?
There is nothing that can't be solved. Just people that can't solve it. :)

Here it is:
	g_pd3dDevice->SetRenderState( D3DRS_LIGHTING, TRUE );	ZeroMemory( &light, sizeof(D3DLIGHT9) );	light.Type       = D3DLIGHT_POINT;	light.Diffuse.r  = 1.0f;	light.Ambient.r  = 1.0f;	light.Diffuse.g  = 1.0f;	light.Ambient.g  = 1.0f;	light.Diffuse.b  = 1.0f;	light.Ambient.b  = 1.0f;	light.Position = D3DXVECTOR3(0.0f, 0.0f, 0.0f);	light.Attenuation0 = 0.0f;	light.Attenuation1 = 0.0f;	light.Attenuation2 = 1.0f;	vecDir = D3DXVECTOR3(0.0f,1.0f,0.0f);     //its from the spot	D3DXVec3Normalize( (D3DXVECTOR3*)&light.Direction, &vecDir );	light.Range       = 1000.0f;	g_pd3dDevice->SetLight( 0, &light );	g_pd3dDevice->LightEnable( 0, TRUE );

Still not working.
