Tsg3DNavigator

The Tsg3DNavigator class descends from the TGLSceneViewer component that is a part of GLScene library.

Tsg3DNavigator = class(TGLSceneViewer)

Properties	Description
`Axes`	The property gets the scene's coordinate axes.
`BackgroundColor`	The property gets or sets the color used for filling the background prior to any rendering.
`BoundingSphereRadius`	The property gets the radius of the bounding sphere.
`CameraStyle`	The property gets or sets a camera view.
`DefSceneMatrix`	The property gets the default scene's transformation matrix.
`Filter`	The property gets the file extension filter suitable for dialog's `Filter` property.
`GLDCScene`	The property gets the main object in the scene.
`GLDCTarget`	The property gets the target for the camera.
`GLFreeForm`	The property gets the container object for the mesh of varying 3D formats.
`Lights`	The property gets the light source that lights scene objects by its index.
`LightsCount`	The property gets the number of light sources.
`Orbit3DVisible`	The property gets or sets the value indicating whether 3D Orbit is visible.
`ShowAxis`	The property gets or sets the value indicating whether coordinate axes are visible.
`ShowCubeExtents`	The property gets or sets the value indicating whether extents of the loaded scene are shown as a cube.
`TrianglesCount`	The property gets a total number of triangles in all mesh objects.

Methods	Description
`Clear`	The method frees the scene objects and clears the materials collection.
`Create`	Creates and initializes an instance of the `Tsg3DNavigator` class.
`Destroy`	Destroys the `Tsg3DNavigator` object.
`DoAfterLoadScene`	The method initializes scene parameters.
`IsEmpty`	The method checks whether the scene is empty (i.e. doesn't contain meshes).
`LoadFromFile`	The method loads 3D model from a specified file.
`LoadFromStream`	The method loads 3D model from a specified stream.
`LoadSceneIdentity`	The method sets a single scale and the identity matrix as a scene's matrix.
`Rotate`	The method rotates the scene objects around a specific axis by a predetermined angle.
`SetDefSceneMatrix`	The method sets the scene's transformation matrix by default.
`Translate`	The method adds an offset to the scene's position by using translation vector.

Events	Description
`OnScenePositionChange`	The event occurs when the position of the scene changes.
