Direction- is it eular angles in radians/degrees
- or it's a point where camera should look?
- or its something like unit vector (0.707, 0, 0.707)
Problem trying to set basic camera angle

What represents this vector?
- is it eular angles in radians/degrees
- or it's a point where camera should look?
- or its something like unit vector (0.707, 0, 0.707)

maybe this help you
following code transform eular angles (rotation) to directions
and its up to you but its better if you make your camera look side "direction"
following code transform eular angles (rotation) to directions
procedure RotationToDirection(Rotation:TD3DVector; var Direction, Up, Right:TD3DVector);var m,m2:TD3DMatrix;begin D3DXMatrixRotationX(m2,-DegToRad(Rotation.X)); D3DXMatrixRotationY(m,-DegToRad(Rotation.Y)); D3DXMatrixMultiply(m2,m2,m); D3DXMatrixRotationZ(m,-DegToRad(Rotation.Z)); D3DXMatrixMultiply(m2,m2,m); Right:=D3DXVector3(m2._11,m2._12,m2._13); Up:=D3DXVector3(m2._21,m2._22,m2._23); Direction:=D3DXVector3(m2._31,m2._32,m2._33);end;and its up to you but its better if you make your camera look side "direction"

Watch out. Direct3D uses row-vectors, so the transformation of M on x is Mx, not xM. For this reason, transformation matrices compose in the order of:
Mcomposition = Mlast...MsecondMfirst.view = position * rotationD3DXMatrixTranslation(&position, -X, -Y, -Z)Admiral
