ImOGuizmo
A simple C++11 header only interactive orientation gizmo for ImGui.
Usage
#include "imoguizmo.hpp"
// it is recommended to use a separate projection matrix since the values that work best
// can be very different from what works well with normal renderings
// e.g., with glm -> glm::perspective(glm::radians(90.0f), 1.0f, 0.1f, 1000.0f);
// optional: configure color, axis length and more
// ImOGuizmo::config.axisLengthScale = 1.0f;
// specify position and size of gizmo (and its window when using ImOGuizmo::BeginFrame())
ImOGuizmo::SetRect(0.0f /* x */, 0.0f /* y */, 120.0f /* square size */);
ImOGuizmo::BeginFrame(); // to use you own window remove this call
// and wrap everything in between ImGui::Begin() and ImGui::End() instead
// optional: set distance to pivot (-> activates interaction)
if(ImOGuizmo::DrawGizmo(viewMatrix, projMat, pivotDistance /* optional: default = 0.0f */))
{
// in case of user interaction viewMatrix gets updated
