ImGizmo is a small (.h and .cpp) library built ontop of Dear ImGui that allow you to manipulate(Rotate & translate at the moment) 4x4 float matrices. No other dependancies. Coded with Immediate Mode (IM) philosophy in mind.

// call BeginFrame right after ImGui_XXXX_NewFrame();

void BeginFrame();

// return true if mouse cursor is over any gizmo control (axis, plan or screen component)

bool IsOver();

// return true if mouse IsOver or if the gizmo is in moving state

bool IsUsing();

// enable/disable the gizmo. Stay in the state until next call to Enable. // gizmo is rendered with gray half transparent color when disabled

void Enable(bool enable);

// call it when you want a gizmo // Needs view and projection matrices. // matrix parameter is the source matrix (where will be gizmo be drawn) and might be transformed by the function. Return deltaMatrix is optional // translation is applied in world space // rotation is applied in local space // Note: all matrices are 4x4 float matrix. OpenGL style.

enum MODE { TRANSLATE, ROTATE };

**void Mogwai(const float *view, const float *projection, MODE mode, float matrix, float deltaMatrix = 0);
