Function `Axis(ImVec2 pos, const glm::mat4& modelView, float size = 20.f)`
|
|
which display right-handed axis in a ImGui window.
|
|
|
|
Example
|
|
|
|
```cpp
|
|
{ // 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);
|
|
}
|
|
```
