Interactivity & Widgets
Since Slope works on top of polyscope, you keep the control over the camera with usual mouse control.
To make interactive presentations, you can use ImGui widgets as a primitive:
float* f = new float(1); // make sure to allocate on heap
show << Point::Add([f](TimeObject t) {
scalar th = (*f)*t.inner_time;
return vec(cos(th),sin(th),0);
});
show << ImGuiWidgets::Add([f]() {
ImGui::SliderFloat("speed",f,0,10);
},"window name");
ImGuiWidgets::Add(std::function<void()>& callback,std::string window_name)
