C++ (Cpp) vtkmatrix Examples

Example #1

File: widget.cpp Project: ArkaJU/opencv

void cv::viz::Widget3D::setPose(const Affine3d &pose)
{
    vtkProp3D *actor = vtkProp3D::SafeDownCast(WidgetAccessor::getProp(*this));
    CV_Assert("Widget is not 3D." && actor);

    vtkSmartPointer<vtkMatrix4x4> matrix = vtkmatrix(pose.matrix);
    actor->SetUserMatrix(matrix);
    actor->Modified();
}

Example #2

File: precomp.hpp Project: elsuizo/opencv

            static vtkSmartPointer<vtkPolyData> TransformPolydata(vtkSmartPointer<vtkPolyData> polydata, const Affine3d& pose)
            {
                vtkSmartPointer<vtkTransform> transform = vtkSmartPointer<vtkTransform>::New();
                transform->SetMatrix(vtkmatrix(pose.matrix));

                vtkSmartPointer<vtkTransformPolyDataFilter> transform_filter = vtkSmartPointer<vtkTransformPolyDataFilter>::New();
                VtkUtils::SetInputData(transform_filter, polydata);
                transform_filter->SetTransform(transform);
                transform_filter->Update();
                return transform_filter->GetOutput();
            }

Example #3

File: precomp.hpp Project: elsuizo/opencv

            static vtkSmartPointer<vtkPolyData> TransformPolydata(vtkSmartPointer<vtkAlgorithmOutput> algorithm_output_port, const Affine3d& pose)
            {
                vtkSmartPointer<vtkTransform> transform = vtkSmartPointer<vtkTransform>::New();
                transform->SetMatrix(vtkmatrix(pose.matrix));

                vtkSmartPointer<vtkTransformPolyDataFilter> transform_filter = vtkSmartPointer<vtkTransformPolyDataFilter>::New();
                transform_filter->SetTransform(transform);
                transform_filter->SetInputConnection(algorithm_output_port);
                transform_filter->Update();
                return transform_filter->GetOutput();
            }

Example #4

File: widget.cpp Project: ArkaJU/opencv

void cv::viz::Widget3D::updatePose(const Affine3d &pose)
{
    vtkProp3D *actor = vtkProp3D::SafeDownCast(WidgetAccessor::getProp(*this));
    CV_Assert("Widget is not 3D." && actor);

        return;
    }

    Affine3d updated_pose = pose * Affine3d(*matrix->Element);
