imgui_axis.hpp

Function Axis(ImVec2 pos, const glm::mat4& modelView, float size = 20.f) which display right-handed axis in a ImGui window.

Example

{  // Display orientation axis at the bottom left corner of the window
float  axisSize = 25.F;
ImVec2 pos      = ImGui::GetWindowPos();
pos.y += ImGui::GetWindowSize().y;
pos += ImVec2(axisSize * 1.1F, -axisSize * 1.1F) * ImGui::GetWindowDpiScale();  // Offset
ImGuiH::Axis(pos, CameraManip.getMatrix(), axisSize);
}

imgui_camera_widget.h

functions in ImGuiH

• CameraWidget : CameraWidget is a Camera widget for the the Camera Manipulator
• SetCameraJsonFile : set the name (without .json) of the setting file. It will load and replace all camera and settings
• SetHomeCamera : set the home camera - replace the one on load
• AddCamera : adding a camera to the list of cameras

imgui_orient.h

struct ImOrient

brief This is a really nice implementation of an orientation widget; all due respect to the original author ;)

This is a port of the AntTweakBar orientation widget, which is a 3D orientation widget that allows the user to specify a 3D orientation using a quaternion, axis-angle, or direction vector. It is a very useful widget for 3D applications.
