C++ (Cpp) SetLookat Examples

Example #1

File: Camera.cpp Project: redclock/GIEngine

CCamera::CCamera(void)
{
    m_LiftAngle = 0.0f;
    SetUp(0, 1, 0);
    SetLookat(0, 0, 0);
    SetEye(1, 0, 1);
    UpdateMatrix();
}

Example #2

File: Camera.cpp Project: chqhso/DirectX

void Camera::SetView(const Vector3& pvEye, const Vector3& pvLookat, const Vector3& pvUp){
	SetEye(pvEye);
	SetLookat(pvLookat);
	SetUp(pvUp);
	
	m_View = Normalized(m_Lookat - m_Eye);
	m_Cross = Cross(m_Up, m_View);

	m_matView = LookAt(m_Eye,m_Lookat, m_Up);
}

Example #3

File: ObjectRotateCamera.cpp Project: redclock/GIEngine

void CObjectRotateCamera::SetCenter(float x, float y, float z)
{
    SetLookat(x, y, z);
    m_center = Point3(x, y, z);
    Point3 eye = Point3(vEyePt.x, vEyePt.y, vEyePt.z);
    Point3 dir = eye - m_center;
    m_radius = dir.GetLength();
    Point3 angle = Dir2Angle(eye - m_center);
    m_anglex = angle.x;
    m_anglez = angle.y;
}

Example #4

File: ObjectRotateCamera.cpp Project: redclock/GIEngine

CObjectRotateCamera::CObjectRotateCamera()
{
    m_axisX = Point3(1, 0, 0);
    m_axisY = Point3(0, 1, 0);
    m_axisZ = Point3(0, 0, 1);
    
    m_anglex = 0;
    m_anglez = 0;
    m_radius = 10;
    SetLookat(0, 0, 0);
    m_center = Point3(0, 0, 0);

    vUpVec = D3DXVECTOR3(0, 0, 1);

    Point3 eye = Angle2Pos(m_anglex, m_anglez);
    SetEye(eye.x, eye.y, eye.z);

    m_lastDown[0] = false;
    m_lastDown[1] = false;

    m_lastx = 0;
    m_lasty = 0;

}
