(REALLY) Wierd Raycasting Problem

I'm new to 3D, and I'm trying to use raycasting in my game to see if the mouse is over the sun. However, when I have the cursor over the sun when the program starts, onsun is false. As I move towards the sun, it stays false until the moment I pass the sun. (Basically, it thinks I'm facing the sun when I'm facing the exact opposite direction.) Here's my code:

	D3DXVECTOR3 ForMouse;
	ForMouse = MGM_MakeRay(0.78f,4/3,g_Mouse.GetMousePos().x,g_Mouse.GetMousePos().y,100);

	float myc[3] = {0,0,0};
	float myo[3];
	g_Camera.GetPosition(myo[0],myo[1],myo[2]);
	float myd[3] = {ForMouse.x,ForMouse.y,ForMouse.z};
	float junk[3];

	if ( SphereRayCollision(myc,10,myo,myd,junk) ) {
		onsun = true;
	} else {
		onsun = false;
	}
    

And here is the MGM_MakeRay function:

D3DXVECTOR3 MGM_MakeRay(float FOV,float AspectRatio,WORD MouseX,WORD MouseY,float range)
{

	D3DXVECTOR3 LineEnd,CameraSpacePos;
	float NMouseX,NMouseY,det;
	D3DXMATRIX matView;

	NMouseX=1.0 - 2.0*MouseX/640;
	NMouseY=1.0 - 2.0*MouseY/480;

	//is FOV in radians
	CameraSpacePos.y=(NMouseY*tan(FOV/2.0));
	CameraSpacePos.x=((-NMouseX*AspectRatio)*tan(FOV/2.0));

	LineEnd.x=range*CameraSpacePos.x;
	LineEnd.y=range*CameraSpacePos.y;
	LineEnd.z=range;

	g_pDevice->GetTransform(D3DTS_VIEW,(D3DMATRIX *)&matView);
	D3DXMatrixInverse(&matView,&det,&matView);
	D3DXVec3TransformCoord(&LineEnd,&LineEnd,&matView);

	return LineEnd;

}
    

And here is the definition of SphereRayCollision: (point is the point of intersection it finds)

bool SphereRayCollision(float center[3], float radius,
                        float origin[3], float direction[3],
                        float point[3]);
    

Thanks (I'm using D3D 8 if it matters). EDIT: Got rid of those lines (see next post). [edited by - rjahrman on August 6, 2002 3:03:10 PM] [edited by - rjahrman on August 6, 2002 3:50:26 PM]
