; ============================================================================== ; ; Imaging & Visualization Toolkit (IVT) configuration file ; Copyright (c) 2001 Siemens Corporate Research ; All Rights Reserved ; ; This file contains configuration parameters for the Imaging & Visualization ; Toolkit (IVT). IVT will look for this file in the following locations, ; respectively: ; 1) The path and filename defined in an environment variable called ; IVT_CONFIG_FILE. This allows you to rename this file and place it ; in any directory you wish. ; 2) The current directory where the application is running. ; 3) The default Windows directory, which is usually C:\Winnt on ; Windows NT systems or C:\Windows on Windows 95 systems. ; ; If the file is not found in any of the above locations, IVT will ; use hardcoded default values (the same default values are also ; indicated in the comments below). ; ; Notation used in this file: ; ; [Section Name] ; ParameterName = Value ; ; Where Value can be a number or a character string, optionally delimited ; by double quotes. Comment lines must use a semicolumn as the first character. ; If parameters are invalid or missing, IVT will use hardcoded defaults. ; ; ============================================================================== ; ============================================================================== ; ; Section: IVT ; Purpose: Configuration of IVT system parameters ; Parameters: ; FileVersion: Current file version, used for internal compatibility test. ; ThreadingModel: Threading model to be used by IVT library. ; Values from 1 to 3 can be specified. Default value is 1. ; 1 - Apartment Threading model. A single and the same thread is ; allowed to make API calls. ; ; 2 - Free threading model. Multiple threads can access IVT APIs. ; 3 - No threading model. Applications' responsibility to synchronize ; access to IVT APIs. ; CubicAmplitudeNormal: This parameter controls the amplification of high frequencies ; (i.e. sharpening) in bicubic interpolation when using the ; RS2_CUBIC2 and V2_CUBIC2 interpolation modes. Its value ranges ; from -3.0 to 0.0, where the value -0.5 is the optimum level of ; sharpening, while values less than -0.5 produce more sharpening ; and values greater than -0.5 cause more blurring (although values ; greater than -0.4 cause a rapid falloff between interpolated ; pixels, causing noticeable artifacts at high zoom factors). ; CubicAmplitudeSharp: This parameter controls the amplification of high frequencies ; in bicubic interpolation when using the RS2_CUBIC3 and V2_CUBIC3 ; interpolation modes (see description of CubicAmplitudeNormal). ; CubicAmplitudeVerySharp: This parameter controls the amplification of high frequencies ; in bicubic interpolation when using the RS2_CUBIC4 and V2_CUBIC4 ; interpolation modes (see description of CubicAmplitudeNormal). ; FilteredDownsampling: Enables filtered downsampling, which eliminates aliasing ; in images scaled down by a factor less than 1.0 (when ; using bilinear or bicubic interpolation), but requires ; much greater processing time. When this parameter is set ; to TRUE, images are convolved with an adaptive 3x3 smoothing ; kernel for scaling factors > 1.0 <= 0.5, while they are averaged ; with a variable size box filter for scaling factors < 0.5. This ; filtering step prior to resampling greatly reduces aliasing artifacts. ; ForceBicubic: When this parameter is TRUE, bilinear interpolation is forced ; to be bicubic interpolation instead. The ForcedCubicAmplitude ; parameter specifies the amplitude of the bicubic interpolation. ; Bilinear interpolation suffers from noticeable aliasing artifacts, ; in particular for scaling factors between 0.5 and 1.5. By enabling ; this parameter, the artifacts can be greatly reduced with a sharp ; cubic convolution amplitude. ; ForcedCubicAmplitude: This parameter controls the amplification of high frequencies ; in bicubic interpolation when the ForceBicubic parameter is TRUE. ; The default value of -1.0 is ideal for reducing resampling artifacts, ; in particular for scaling factors between 0.5 and 1.5. ; SMPEnabled: Enable/Disables symmetric multi-processing, when available. When ; set to 1 (TRUE), symmetric multi-processing is used when multi-processors ; are available. When set to 0 (FALSE), symmetric multi-processing is ; not used. ; DelayedMappingThreshold: This flag is used when IVT needs to resample the volume. This ; allows IVT to delay the locking of internally created resampled volume into ; process virtual memory until slice data is actually touched. ; This value specifies the minimum volume size in bytes for which such a ; delayed mapping will be performed. For any volume of size less then that ; all the slices will be mapped form the beginning. ; When set to 0, deleyedMapping is mapping is disabled, meaning the entire ; resampled volume is locked into memory at the begining (old behavior). ; IPPEnabled: This parameter enables or disables the use of IPP libraries in IVT resampling ; use cases. If enabled, IVT uses IPP libraries to do resampling otherwise IVT ; uses its own implementation. ; Values: ; FileVersion (FLT32) range: N/A, default = 1.0 ; CubicAmplitudeNormal (FLT32) range: -3.0 to 0.0, default -0.5 ; CubicAmplitudeSharp (FLT32) range: -3.0 to 0.0, default -0.75 ; CubicAmplitudeVerySharp (FLT32) range: -3.0 to 0.0, default -1.0 ; FilteredDownsampling (BOOL) range: 0 (FALSE) to 1 (TRUE), default = 0 (FALSE) ; ForceBicubic (BOOL) range: 0 (FALSE) to 1 (TRUE), default = 0 (FALSE) ; ForcedCubicAmplitude (FLT32) range: -3.0 to 0.0, default -1.0 ; SMPEnabled (BOOL) range: 0 (FALSE) to 1 (TRUE), default = 1 (TRUE) ; DelayedMappingThreshold (UINT64) range: 0 to max. value of UINT64, default = 10485760 (bytes) ; IPPEnabled (BOOL) range: 0 (FALSE) to 1 (TRUE), default = 1 (TRUE) ; ============================================================================== [IVT] FileVersion = 1.0 ThreadingModel=3 CubicAmplitudeNormal = -0.5 CubicAmplitudeSharp = -0.75 CubicAmplitudeVerySharp = -1.0 FilteredDownsampling = FALSE ForceBicubic = FALSE ForcedCubicAmplitude = -1.0 SMPEnabled = TRUE DelayedMappingThreshold = 10485760 IPPEnabled = TRUE ; ============================================================================== ; ; Section: Default Material ; Purpose: Configuration of Default Material parameters ; Parameters: ; Ambient: The amount of light coming from an object regardless ; of the position of the light and the viewer. ; Diffuse: The amount of light reflection generated by a light ; shining on an object surface, radiating outward in ; a uniform and view independent manner. ; Specular: The amount of light that reflects off an object in ; the way that a mirror reflects an image. This type of ; reflection is view dependent, and it is associated ; with the specular highlights of an object. ; Shininess: This parameter controls the size and brightness of the ; specular highlights. You can assign a number in the ; range 1.0 to 128.0: the higher the value, the smaller ; and brighter (more focused) the highlight. ; ; Values: ; ColorRed (FLT32) range: 0.0 to 1.0, default = 1.0 ; ColorGreen (FLT32) range: 0.0 to 1.0, default = 1.0 ; ColorBlue (FLT32) range: 0.0 to 1.0, default = 1.0 ; Ambient (FLT32) range: 0.0 to 1.0, default = 0.25 ; Diffuse (FLT32) range: 0.0 to 1.0, default = 0.6 ; Specular (FLT32) range: 0.0 to 1.0, default = 0.0 ; Shininess (FLT32) range: 0.0 to 128.0, default = 0.0 ; ; ============================================================================== [Default Material] Ambient = 0.25 Diffuse = 0.6 Specular = 0.0 Shininess = 0.0 ; ============================================================================== ; ; Section: ShearWarp ; Purpose: Configuration of IVT shear-warp plugin parameters ; Parameters: ; SubsampledSize: Maximum size of the subsampled volume used for high speed, ; low quality volume renderings. ; ClippingMPR: A boolean flag to enable/disable clipping with texture ; mapped MPR. If FALSE, volume clipping boxes are rendered ; as flat shaded planes. If TRUE, they are rendered as ; texture-mapped planes showing the grayscale voxel values ; on the surface of the plane. This texture mapping feature ; accesses the original grayscale voxel values, and therefore ; uses more memory. ; Values: ; SubsampledSize (SINT32) range: 32 to 256, default = 128 ; ClippingMPR (BOOL) range: 0 (FALSE) to 1 (TRUE), default = 0 (FALSE) ; ; ============================================================================== [ShearWarp] SubsampledSize = 128 ClippingMPR = FALSE ; ============================================================================== ; ; Section: MPR ; Purpose: Configuration of IVT MPR plugin parameters ; Parameters: ; FastMPRTimeout: Maximum time (in milliseconds) during which the system will use ; a very fast MPR algorithm without memory management. If the ; algorithm fails to produce an image within the specified time, ; it will switch to a slower algorithm which uses memory management. ; Setting this parameter to 0 completely bypasses the fast algorithm ; and forces the system to always use memory-managed MPR (up to 8 fps). ; The fast algorithm (up to 30 fps) is ideal when the volume data ; fits entirely in physical memory, but if the data is larger than ; the available physical memory this algorithm could take forever ; to produce an MPR image, because of excessive disk paging. When ; the fast algorithm is slowed down by paging, this parameter allows ; to automatically detect this delay and switch to an algorithm ; which minimizes disk paging (performance will then vary depending ; on disk transfer speed, usually 10 Mb of data per second). ; Once the slower algorithm is activated, it remains into effect ; until the data can be rendered again at a faster rate. ; ; HTEnabled: Flag indicating whether internal SMP processing will try to utilize ; hyperthreading number of threads or only up to the number of phyical ; CPUs. ; ; Values: ; FastMPRTimeout (SINT32) range: 0 to 1000, default = 250 ; HTEnabled: (BOOL) range: 0 (FALSE) to 1 (TRUE), default = 0 (FALSE) ; ; ============================================================================== [MPR] FastMPRTimeout = 250 HTEnabled = FALSE ; ============================================================================== ; ; Section: ScrollMPR ; Purpose: Configuration of IVT Scroll MPR plugin parameters ; Parameters: ; ; HTEnabled: Flag indicating whether internal SMP processing will try to utilize ; hyperthreading number of threads or only up to the number of phyical ; CPUs. ; ; Values: ; HTEnabled: (BOOL) range: 0 (FALSE) to 1 (TRUE), default = 0 (FALSE) ; ; ============================================================================== [ScrollMPR] HTEnabled = FALSE ; ============================================================================== ; ; Section: Gl3DTex ; Purpose: Configuration parameters for the standard IVT 3D texture based renderer. ; Parameters: ; MaxTexelsX: The maximum number of texels used for the X dimension of a volume. ; MaxTexelsY: The maximum number of texels used for the Y dimension of a volume. ; MaxTexelsZ: The maximum number of texels used for the Z dimension of a volume. ; Values: ; MaxTexelsX: (SINT32) range: 64 to 512, default = 256 ; MaxTexelsY: (SINT32) range: 64 to 512, default = 256 ; MaxTexelsZ: (SINT32) range: 64 to 512, default = 256 ; ============================================================================== [Gl3DTex] MaxTexelsX = 256 MaxTexelsY = 256 MaxTexelsZ = 256 ; ============================================================================== ; ; Section: GlNv2x ; Purpose: Configuration parameters for the IVT OpenGL based renderer for nVidia 2x hardware. ; Parameters: ; MaxTexelsX: The maximum number of texels used for the X dimension of a volume. ; MaxTexelsY: The maximum number of texels used for the Y dimension of a volume. ; MaxTexelsZ: The maximum number of texels used for the Z dimension of a volume. ; Quantize8: Indicator if data is quantized to 8-bits within the renderer. ; This option values can be used to improve performance & reduce the ; amount of texture required (a critical resource) at the expense ; of quality. The difference is often hard to discern. ; HighQualityGradients: Indicator if high quality gradients (Sobel) are to be ; used instead of standard gradient (central difference). High ; quality gradients yield better results, but are more computationally ; expensive. ; Values: ; MaxTexelsX: (SINT32) range: 64 to 512, default = 256 ; MaxTexelsY: (SINT32) range: 64 to 512, default = 256 ; MaxTexelsZ: (SINT32) range: 64 to 512, default = 256 ; Quantize8: (BOOL) default = TRUE ; HighQualityGradients: (BOOL) default = FALSE ; ============================================================================== [GlNv2x] MaxTexelsX = 256 MaxTexelsY = 256 MaxTexelsZ = 256 Quantize8 = FALSE HighQualityGradients = FALSE ; ============================================================================== ; ; Section: GlNvBrick ; Purpose: Configuration parameters for the IVT OpenGLbricking renderer ; for nVidia 4x hardware and later. ; Parameters: ; HqTexBudget: The maximum amount of memory that can be allocated for high quality texture. ; The value is expressed in megabytes (where 1 MB = 1024 B). ; LqTexBudget: The maximum amount of memory that can be allocated for lowquality texture. ; The value is expressed in megabytes (where 1 MB = 1024 B). ; LqTexQuantize8: An indication if the low quality texture is quantized to 8-bits. ; NonContigLoad: The threshold at which input slice data is copied to an internal buffer ; to ensure it is contiguous. Loading slice data is more efficient when ; input slice data is contiguous. An intermediate internal buffer is used ; when the specified threshold is less than the ratio of the number of ; to the noncontiguous slices to the number of slices. ; Quantize8: Indicator if data is quantized to 8-bits within the renderer. ; This option values can be used to improve performance & reduce the ; amount of texture required (a critical resource) at the expense ; of quality. The difference is often hard to discern. ; Values: ; HqTexBudget: (FLT64) range: 1.0 to 128.0, default = 32.0 ; LqTexBudget: (FLT64) range: 1.0 to 128.0, default = 64.0 ; LqTexQuantize8: (BOOL) default = TRUE ; NonContigLoad: (FLT64) range: 0.0 to 1.0, default = 0.9 ; Quantize8: (BOOL) default = TRUE [GlNvBrick] HqTexBudget = 32.0 LqTexBudget = 64.0 Quantize8 = TRUE ; ============================================================================== ; ; Section: Memory Manager ; Purpose: Configuration parameters for the management of physical memory ; (RAM) and disk space used by memory-mapped objects. ; ; Parameters: ; Mode: Local setting that defines the mode of operation. ; If the default value of 0 is set, the memory manager ; operates in central service mode. If the mode is set to ; 1 the memory manager operates in No-Server mode. All ; other values are reserved for internal use. ; Service: Defines a socket service number, which the memory manager ; should bind to. If the default value is 12997. ; OptimizeRam: Enables/disables optimization. When set to 1 (TRUE), ; the disk paging of memory-mapped buffers in and out of ; physical memory is optimized. When set to 0 (FALSE), ; disk paging is entirely up to operating system. ; MinRamThreshold: If OptimizeRam is enabled, this parameter specifies the ; minimum amount of free physical memory (in MB), which ; will cause the system to begin flushing memory-mapped ; objects out of physical memory. The default value is 8. ; TargetRecoveredRam: If OptimizeRam is enabled, this parameter specifies the ; target amount of free physical memory (in MB), which will ; be recovered when memory flushing is triggered. The ; default value is 32. ; LowSpaceTestFreq: Number of seconds indicating how frequently the memory ; manager checks the available disk space. The default ; value is 60. ; TotMemMapDisks: Total number of disks used for memory-mapping. For each ; disk 1 to TotMemMapDisks, a "MMDisk_#" section must be ; declared. ; DynamicMapping: Enable/disable dynamic mapping. When set to 1 (TRUE), ; the on demand mapping/unmapping is activated, ie. memory ; manager can unmap the buffer out of virtual address space if no ; application is using the buffer. When set to 0 (FALSE), ; the on demand mapping/unmapping is disabled. ie. the mapped ; buffer stays in virtual address space until application ; deletes the buffer. ; Values: ; Mode (SINT32) range: 0 to 1, default = 0 ; Service (SINT32) range: 0 to 65535, default = 12997 ; OptimizeRam (BOOL32) range: 0 (FALSE) to 1 (TRUE), default = 1 (TRUE) ; MinRamThreshold (SINT32) range (Mb): 1 to total physical memory, default = 8 ; TargetRecoveredRam (SINT32) range (Mb): MinRamThreshold to total physical memory, ; default = 32 ; LowSpaceTestFreq (SINT32) range: 1 to 60, default = 60 ; TotMemMapDisks (SINT32) range: 1 to 100, default = 1 ; DynamicMapping (BOOL32) range: 0 (FALSE) to 1 (TRUE), default = 1 (TRUE) ; ; ============================================================================== [Memory Manager] Mode = 1 Service = 12997 OptimizeRam = TRUE MinRamThreshold = 8 TargetRecoveredRam = 32 MinDiskThreshold = 0.1 TargetRecoveredDisk = 0.2 LowSpaceTestFreq = 60 TotMemMapDisks = 1 DynamicMapping = TRUE ; ============================================================================== ; ; Section: MMDisk_n (where "n" ranges from 1 to TotMemMapDisks) ; Purpose: Configuration parameters for the management of disks being ; used by memory-mapped objects. ; Parameters: ; Path: Pathname of the disk and directory where memory ; mapped files can be created ; MaxDiskSpaceUsed: Maximum amount of disk space which will be used for ; memory mapping ; FreeSpaceLimit: The amount of free disk space which should be ; left available on the disk ; ; Values: ; Path (CHAR*) range: N/A, default = OS_DEFAULT ; ; If the specified pathname is invalid, the default path is used instead. ; When OS_DEFAULT is used instead of a specific pathname, the system ; determines the pathname as follows: ; 1.
