# Camera2D demo with static elements
An approach for having certain elements not affected by the camera

### DemoCamera2DManual01
Demonstrate the use of `Camera2DManual` for manual camera control.
The application is configured with a 720x720 window size. Within the program, a custom camera (`Camera2DManual`)
is initialized and used to create isolated drawing scopes. The `isolated` method is used to overlay different
drawing operations while maintaining individual camera states, ensuring proper transformations for specific elements.
Three circles are drawn on the canvas: a small pink one, a medium white one and a large pink one.
Only the pink ones are affected by the interactive `Camera2DManual`, while the middle white circle is outside
the camera's isolated scope.

### DemoCamera2DManual02
Demonstrate the use of `Camera2DManual` to independently translate, scale and rotate one contour
in a collection.
When the mouse is clicked, the active contour is transformed using the camera view matrix,
then the camera is reset to its default state and whatever shape is under the mouse becomes
the new active contour.
As the mouse is dragged or its wheel scrolled, the camera is updated, affecting
how the active contour is rendered.

### DemoOrbitalManual01
Demonstrate the use of an orbital camera to render a sphere and a cube in 3D space as wireframe meshes, positioned
and rendered independently using the camera's isolated drawing state. A stationary pink circle is also drawn in the
center of the scene.
Functionality:
- Initializes a sphere mesh and a cube mesh with predefined dimensions.
- Spawns an orbital camera, initially positioned away from the origin, to allow for focused rendering.
- Renders 3D wireframe shapes (sphere and cube) using the camera's isolated perspective.
- Draws a static 2D pink circle overlay at the window center.
