Querying Driver Attributes and Capabilities


[VAR {var}] LMI [DRI/VER {string}] Q/UERY {APIVER/SION \| DRIVERVER/SION \| BAN/NER \| LAST ERR/ORMESSAGE \| MAX/IMUM {MOD/ELS \| VIEWS \| REGIONSOFINT/EREST \| HIGHL/IGHTREGIONS \| CLASHVOL/UMES \| VIEWQ/UALITY {IN/SIDE \| OUT/SIDE} \| VIEWP/ORT {W/IDTH \| H/EIGHT}} SUPP/ORT {FBCLIP/PING \| RENDERFAST \| LOWRESEVERYWHERE \| TESTVOLUMEFAST \| TESTGEOMETRYEXACT}}


{var}	variable name
{string}	driver name and connection details in the following format, enclosed in single quotes: {name}[\|{path to dll}[\|{vendor’s connect string}]]

This command connects to, and queries attributes of, the named driver. The result string is returned in variable {var}, or if this is omitted, output in the command window.

The DRIVER {string} subcommand should be included the first time an LMI command is used for a particular driver, but need not be repeated for subsequent calls to the same driver. See Driver Subcommand - Accessing Drivers.

The available attributes are:


APIVERSION	The version string for the LMI.
DRIVERVERSION	The version string for the driver.
BANNER	The driver manufacturer’s banner text.
LAST ERRORMESSAGE	The last error message (or an empty string if no error has occurred).
MAXIMUM MODELS	The maximum number of models that can be opened simultaneously (range 1 ‑ unlimited).
MAXIMUM VIEWS	The maximum number of views that can be rendered efficiently (range 1 ‑ unlimited). Note: since calls to render views are made sequentially, any number of views can be rendered, however the rendered images are generally cached by the vendor software for efficiency, and this command returns the maximum number of views for which this caching is supported.
MAXIMUM REGIONSOFINTEREST	The maximum number of regions of interest that the driver supports (range 0 ‑ unlimited). Regions of interest define areas where a higher view quality may be used.
MAXIMUM HIGHLIGHTREGIONS	The maximum number of highlighted regions that the driver can support (range 0 ‑ unlimited).
MAXIMUM CLASHVOLUMES	The maximum number of highlighted clash volumes that the driver can support (range 0 ‑ unlimited).
MAXIMUM VIEWQUALITY	The maximum view quality that the driver supports INSIDE or OUTSIDE the regions of interest (range 1 or higher).
MAXIMUM VIEWPORT WIDTH / HEIGHT	The maximum viewport width / height that the driver supports (range 1 ‑ unlimited).
SUPPORT FBCLIPPING	Whether the driver supports front and back clipping planes (‘true’ or ‘false’).
SUPPORT RENDERFAST	Whether the driver supports fast rendering (‘true’ or ‘false’).
SUPPORT LOWRESEVERYWHERE	Whether the driver supports rendering in low resolution everywhere mode (‘true’ or ‘false’).
SUPPORT TESTVOLUMEFAST	Whether the driver supports a fast (but less accurate) version of volume testing for clashing.
SUPPORT TESTGEOMETRYEXACT	Whether the driver supports testing geometry for clashing at the “exact check” level.
