Enhancements

Experimental Cellular Volumes

Cutting planes and sections now intersect cellular volume geometry and interpolate values on the resulting cut surface(s). Capping faces produced by cutting planes through cellular volume geometry can be extracted in the same way as through shell faces.

Offscreen Rendering

Offscreen rendering now handles transparent backgrounds and does not render transparent lines and markers when widnow opacity is set to zero.

3D Part Viewer

Accuracy of the percent of VRAM used by 3D Partviewer is improved.

Functional Changes

  • HC_Show_Device_Info The video memory returned by HC_Show_Device_Info is reported in Mebibyte (MiB) instead of Megabyte (MB).
  • Highlights Highlights of different styles on different segments display the requested highlight. Geometry remains visible when segements with line weight greater than zero are highlighted. Individual shell vertices colored by RGBA can be highlighted.
  • Face Lighting and Patterns Lighting appears correct when parts of a face are deleted. When HC_Set_Driver_Options(“window opacity=0”) is set the face pattern applied is also rendered.
  • Show_Owner_By_Key Show_Owner_By_Key returns with correct key in the C# interface.
  • Windows SDK Support All Windows platform sandboxes have been updated to Windows SDK 10.0.22621.3233.
