2008 r8- Features
-
- AGI.Graphics.Overlays
-
- Added an initial version of overlays. Overlays are used to render objects in 2D screen-space on top of a 3D scene. For example, overlays can be used to display your company's logo, create a heads-up display (HUD), or create a translucent user interface. See the overview for details.
- AGI.Graphics.Primitives
-
- Added a DisplayConditionPerPoint property to the point batch and a DisplayConditionPerString property to the text batch. This property is evaluated per point/string in the batch as opposed to the DisplayCondition property which is evaluated for the entire batch.
- AGI.Graphics.Imaging.Video
-
- IAgGxVideoData has improved support for asynchronous network streams and H.264 transport streams.
- Added NextFrame and NextAnimationFrame to IAgGxVideoData to allow for more fine grained control of frame decoding.

- Summary of Breaking Changes
-
- AGI.Graphics.Scene3D
-
- The PickedObject property on AgGxPickResult is now named Objects. Instead of a single object, now it is a collection of all the objects on the pick stack when the pick was recorded. See the Picking Overview.

-
- All initialize methods on AgGxPrimitiveTriangleMesh, AgGxPrimitivePolyline, and AgGxPrimitivePointBatch now have an AgGxVertexUpdate parameter that influences the efficiency of Set and SetPartial methods. See the Performance Overview.
- Primitive initialize methods no longer have the AgGxMovement parameter. Since it is only used for culling in the primitive manager, it is now the second parameter to AgGxPrimitiveManager.Add. The composite primitive, AgGxPrimitiveComposite, no longer has an initialize method since it only took the AgGxMovement parameter. These changes do not affect the prototype primitives: AgGxPrimitiveMarker and AgGxPrimitiveMeshSurface.
- When initializing or setting the polyline or point batch primitive with per-vertex colors, a new parameter, AgGxRenderPassHint, that indicates if the colors are opaque, translucent, or unknown must be provided. This affects InitializeWithColors, InitializeCartographicWithColors, SetWithColors, and SetCartographicWithColors on both AgGxPrimitivePolyline and AgGxPrimitivePointBatch.
- AGI.Graphics
-
- The ConditionalDisplay property on all primitives was renamed to DisplayCondition.
- IAgGxConditionalDisplay was renamed to IAgGxDisplayCondition. All classes that started with AgGxConditionalDisplay, now start with AgGxDisplayCondition.
