Introducing Scalable 5.0

Key Features

• Automatic color and brightness uniformity calibration - compatible with multiple cameras and curved screens.
• DX11 EasyBlend SDK support for dynamic eyepoint, black level and color correction, and image masking.
• Masking panels now support masking custom shapes.

Additional Features

• Added advanced options for handling 360 overlaps with warping boxes.
• Added support for variable overlaps via advanced options.
• Added support for multiple graphics cards driving a single projector on the same PC via an advanced option.
• Added GUI support for camera space control points when using hemisphere screen type.
• Added screen model preview for hemisphere screen type.
• Hemisphere screen type now supports 3D control point overrides.
• Added a denser perspective scene selection.
• Added support for tiling + stacking when showing patterns on warping boxes.
• Orthographic tweaking panel now allows a custom background image to be displayed.
• Control Point Override panel now displays the distance of each control point from the eyepoint.

Optimizations

• Improved the reliability of engage/disengage when using NVIDIA warp.

And there's more...

Usability

• Improved the reliability of engage/disengage when using NVIDIA warp.
• Added selection of camera lens type to the Cameras panel.
• Added a high contrast mode to the Black Level panel.
• Color and Intensity panel can now display the grid and cursor locations.
• Options to set the dimensions of a flat screen now work without a software restart.
• Added keyboard controls to masking panels. These controls are documented in the Help guide for each panel.

Resolved Issues

• Resolved several issues on both Windows and Linux where entering one of the tuning panels would cause the software to hang.
• Fixed a crash when entering the Image Boundary panel without a graphics driver installed or when using Intel Integrated Graphics.
• Resolved an issue with remote NVIDIA warps when using vertically tiled arrangements.
• Resolved an issue where manual Color and Intensity tweaks required a color license in order to apply.
• Resolved several compatibility issues with tuning panels and the use of disabled monitors.
• Resolved an issue where visual artifacts could occur along the edge of a panel in SPA calibrations.
• The SPA Image Boundary panel now properly accounts for camera lens distortion.
• Resolved several issues with datasets not being properly constructed or including incorrect diagnostic images from previous calibrations.
• Resolved an issue where the real-time calibration preview was incorrect for non-spherical dome screens.
• The "Invalid Parameter" error when a camera does not see enough control points has been replaced with a more useful error message.

Known Bugs & Issues

• The SplitFrustum feature is not compatible with many features including black level, image masking, and grid-based software color.
• The Point Grey camera integration is currently not robust to errors.
• EnableDoubleBuffering = false can slow down rendering on NVIDIA systems (referenced in NVIDIA 340.52 driver release notes).
• Hardware license keys can slow down the system significantly.
• Showing test images using Barco pulse API can cause the warp to disengage.
• Testing has shown that currently it may not be possible to calibrate a ScalableDesktop system using both Stacking & Tiling with projectors in portrait mode due to graphics driver errors.
• When using multiple Basler model acA4024-8gc cameras, some cameras may capture an image from a different camera. The known workaround is to use the advanced camera setup UI in the "Cameras" panel.
• Engaging the warp in ScalableDesktop may cause the display client to stop functioning on some systems.
• Linux Display Client:
• • Graphics cards must be arranged in a 1xN configuration for control points to appear in the expected locations.
  • There is currently no way to hide the DisplayClient.
