示例1: InitializeViewToWorldMatrix
void RayTracer::InitializeViewToWorldMatrix(){
assert(m_pRenderAttribute != NULL);
Vector4f up = m_pRenderAttribute->m_ViewFrustrum->m_ViewUpDirection;
Vector4f dir = m_pRenderAttribute->m_ViewFrustrum->m_ViewDirection;
dir.Normalize();
up = up - (up.dot(dir)) * dir;
up.Normalize();
Vector4f w = dir.cross(up);
this->m_ViewToWorld[0] = w[0];
this->m_ViewToWorld[4] = w[1];
this->m_ViewToWorld[8] = w[2];
this->m_ViewToWorld[1] = up[0];
this->m_ViewToWorld[5] = up[1];
this->m_ViewToWorld[9] = up[2];
this->m_ViewToWorld[2] = -dir[0];
this->m_ViewToWorld[6] = -dir[1];
this->m_ViewToWorld[10] = -dir[2];
