What's New in STK Graphics 13.1

Added support for new camera video output format in IAgStkGraphicsCamera interface, ProRes.
A new convenience method, ViewCenralBodyFromPosition, has been added to the IAgStkGraphicsCamera. This will set the camera position to the specified position and look down towards the center of the central body.
Several enums have been renamed to follow a more consistent coding style guideline. Original enums remain but have been marked as deprecated:
- eStkGraphicsCullFace enums replaces eStkGraphicsECullFace enums.
- eStkGraphicsOutlineAppearance enums replaces eStkGraphicsFrontAndBackLines, eStkGraphicsFrontLinesOnly, and eStkGraphicsStylizeBackLines.
- eStkGraphicsPathPrimitiveRemoveLocation enums replaces eStkGraphicsRemoveLocation enums.
- eStkGraphicsStereoProjectionMode enums replaces eStkGraphicsStereoProjection enums.

Changed Classes, Interfaces and Enumerations

Object	Changes	Version
AgEStkGraphicsCameraVideoFormat	Added enum eStkGraphicsCameraVideoFormatProRes	STK 13.1
AgEStkGraphicsCullFace	Added enum eStkGraphicsCullFaceNeither Added enum eStkGraphicsCullFaceFrontAndBack Added enum eStkGraphicsCullFaceFront Added enum eStkGraphicsCullFaceBack Deprecated enum eStkGraphicsECullFaceFront - This enumeration is deprecated. Use eStkGraphicsCullFaceFront instead. Front-facing triangles are culled. Deprecated enum eStkGraphicsECullFaceBack - This enumeration is deprecated. Use eStkGraphicsCullFaceBack instead. Back-facing triangles are culled. Deprecated enum eStkGraphicsECullFaceFrontAndBack - This enumeration is deprecated. Use eStkGraphicsCullFaceFrontAndBack instead. Both front- and back-facing triangles are culled. Therefore, no triangles are rendered. Deprecated enum eStkGraphicsECullFaceNeither - This enumeration is deprecated. Use eStkGraphicsCullFaceNeither instead. No triangles are culled.	STK 13.1
AgEStkGraphicsOutlineAppearance	Added enum eStkGraphicsOutlineAppearanceStylizeBackLines Added enum eStkGraphicsOutlineAppearanceFrontLinesOnly Added enum eStkGraphicsOutlineAppearanceFrontAndBackLines Deprecated enum eStkGraphicsFrontAndBackLines - This enumeration is deprecated. Use eStkGraphicsOutlineAppearanceFrontAndBackLines instead. Both the front and back lines are displayed. Deprecated enum eStkGraphicsFrontLinesOnly - This enumeration is deprecated. Use eStkGraphicsOutlineAppearanceFrontLinesOnly instead. Only the front lines are displayed. This can be used to declutter the outline. Deprecated enum eStkGraphicsStylizeBackLines - This enumeration is deprecated. Use eStkGraphicsOutlineAppearanceStylizeBackLines instead. Both the front and back lines are displayed. The back lines are displayed using a different color, translucency, and width...	STK 13.1
AgEStkGraphicsPathPrimitiveRemoveLocation	Added enum eStkGraphicsPathPrimitiveRemoveLocationFront Added enum eStkGraphicsPathPrimitiveRemoveLocationBack Deprecated enum eStkGraphicsRemoveLocationFront - This enumeration is deprecated. Use eStkGraphicsPathPrimitiveRemoveLocationFront instead. Remove from the front of the line. Deprecated enum eStkGraphicsRemoveLocationBack - This enumeration is deprecated. Use eStkGraphicsPathPrimitiveRemoveLocationBack instead. Remove from the back of the line.	STK 13.1
AgEStkGraphicsStereoProjectionMode	Added enum eStkGraphicsStereoProjectionModeAutomatic Added enum eStkGraphicsStereoProjectionModeParallel Added enum eStkGraphicsStereoProjectionModeFixedDistance Deprecated enum eStkGraphicsStereoProjectionParallel - This enumeration is deprecated. Use eStkGraphicsStereoProjectionModeParallel instead. Parallel projection. Parallel projection will ignore any projection distance that has been set and instead use a parallel projection for each eye... Deprecated enum eStkGraphicsStereoProjectionFixedDistance - This enumeration is deprecated. Use eStkGraphicsStereoProjectionModeFixedDistance instead. Fixed distance projection. Objects at the fixed distance will appear to have no depth. Objects further than the distance will appear to go into the screen... Deprecated enum eStkGraphicsStereoProjectionAutomatic - This enumeration is deprecated. Use eStkGraphicsStereoProjectionModeAutomatic instead. Automatic distance projection...	STK 13.1
IAgStkGraphicsCamera	Added method ViewCentralBodyFromPosition	STK 13.1
