F4.13} Layers

 The Layers tab allows the user to create customized views. The
 user has the possibility to change the fill color of the regions
 displaying regions, materials or even color encoding of biasing,
 cuts, thresholds etc. Moreover The user has the possibility to
 overlay a background image e.g a technical drawing, project
 USRBIN data, BEAM parameters, lattices, voxels, transformations
 as well 3D representations using a raytracing technique. Or a
 combination of any of the above.

 The buttons on the top allow the user to create, rename, clone or
 delete a layer.
 
WARNING:
There are 4 predefined system layers: Boundary Media 3D Lattice where the user can only control the "Options". The "Global" checkbox when ticked makes the layer common to all projects. It saves the information in the flair.ini file rather in the flair project The listbox on the top allows: - to access and modify the various options for each layer type - to turn ON/OFF the visibility of the layer type - Click on <add> or with the keyboard [Ins] to add a new layer - Right-Click to remove the layer or with the keyboard [Del] Buttons: [Apply] Perform the changes and redraws the viewports. Most of the actions are refreshed automatically. [Reset] Reset current layer to the default parameters [Help] Show the documentation page The following layer types are available:

Can slow down the refreshing of display Palette: Select palette to display color information like importances etc.
*******************
* Image *
*******************
Display a background image e.g. a technical drawing of your object properly aligned with the geometry grab-geometry-layers4.gif Image: Click to select the image to display accepted formats png, gif, jpg, tif, bmp Calibrate: Click to open the calibration dialog Alpha: Select transparency/opacity level of the image plot on the back the standard material colors Color Adjust: Interpolate the colors with the black-white range Black: color to use for the #000000 value White: color to use for the #ffffff value Prompt draw: Normally the image drawing is done when the display is idle. Prompt will force to draw the image immediately however rendering the display a bit slow grab-geometry-layers3b.gif The calibration dialog needs at least 3 markers (the more the better) to find the transformation from the image coordinates to the geometry coordinates.
Note:
The markers should not fall all in the same line, otherwise the program cannot calculate the transformation matrix Add add a new marker any point in the image and enter the Ctrl-Click the geometry (x,y,z) corresponding to this point Right-Click on any point to insert a new marker, delete or edit the coordinates of the marker Zoom In or MouseWheel Zoom Out Info To dump to the output window the calibration error Ok To close the window and accept the calibration Cancel To close and forget the calibration Once the image is properly calibrated then it will appear as a background image in the viewport when the appropriate layer is selected.
Note:
Please try to change the colors of your image in order to make it easier visible on the screen grab-geometry-layers3c.gif Final image on the viewport window
*******************
* Userdump *
*******************
Reads the default USERDUMP file and draws the particle trajectories. grab-geometry-layers5.gif Userdump file: file to read Start: Starting event # Events: Number of events to plot Listbox Select particle types to draw as well their limits in energy and track color
*******************
* Usrbin *
*******************
Display cuts of one or multiple USRBINs dynamically in the geometry. Up to 20 usrbin can be loaded and displayed at the same time. The layer index selects the parameters of the specific usrbin. For each displayed pixel, the first USRBIN that includes the displayed location is drawn. Therefore select the finer mesh first and the coarser as last. grab-geometry-layers6.gif USRBIN from Inp Check if you want to display a USRBIN card as a checker grid pattern. Usrbin file: Load USRBIN file Detector: Select detector to display from USRBIN file Norm: Normalization constant to use X-offset: Additional offset to apply to USRBIN Y-offset: To get the offsets from Input select the Z-offset "USRBIN from Inp" select the USRBIN and then switch to file. Rotdefi: Select a ROT-DEFI to be applied to the USRBIN Transparency: Select transparency/opacity level of the usrbin plot on top the standard material colors Prompt Display promptly the usrbins. WARNING can slow down display Palette: Palette to use for this usrbin
Note:
The color scale is not automatically selected you have to define it using the Palette layer grab-geometry-layers4b.gif
*******************
* 3D *
*******************
Display 3D raytraced images behind the viewport. The usual cut will be visible and all transparent object will be filled with the ray-traced image behind. grab-geometry-layers7.gif Perspective: Select orthographic (default) or perspective projection FOV: Field of View in degrees from 0 to 180. It is enabled only in the perspective/combo mode. Ambient Light: Amount of ambient light for dark regions Antialias: Perform super sampling to enhance image
WARNING:
Can slow down considerably the rendering Shadows Enable if you want lights to cast shadows
WARNING:
Will slow down the rendering Edge detection: Draw edges of regions as black lines.
WARNING:
Will slow down the rendering Show errors: Check if you want to display errors as red error lines.
Note:
if the [Show] layer is activated also errors on the displayed projection are also shown from that layer Xray level: Set automatic transparency for each region it finds emulating an xray image Clipped by: Set a clipping body to clip the 3D image Negative clip: Use the negative of the body Project body: Use this body as a projection surface for the USRBIN values. Useful if you want to display fluences in vacuum or in transparent objects. Usrbin as texture: Use the USRBIN values as the surface color texture on regions. If unselected USRBINS will be displayed only on the Projection body grab-geometry-layers5b.gif
*******************
* Palette *
*******************
Select the color band limits, gradient and palette. To be used in combination when showing numerical values, density, biasing, thresholds etc or USRBIN data. Up to 3 different palettes can be used. For example a gray-scale one for plotting densities and a color one for overlaying USRBIN values. grab-geometry-layers8.gif Palette: Select the palette type to use Log: Logarithmic or linear scale Invert: Reverse palette order Transparent(<Min):If selected do not paint anything for values smaller than the palette minimum If not selected all values<Min will be painted with the minimum color Transparent(>Max):If selected do not paint anything for values greater than the palette maximum. If not selected all values>Max will be painted with the maximum color Minimum: Minimum value of the color band Maximum: Maximum value of the color band Colors: Number of colors to be interpolated CPD: Colors per decade. Active when the "Log" option is selected. When modified the Maximum value is calculated as a function from the minimum and the number of colors, to ensure correct rounding of colors per decade. grab-geometry-layers6b.gif A combination of the 3D, USRBIN and Colorband
*******************
* Voxel *
*******************
Select and display ROI (Regions of Interest) embedded in the voxel file. ROI Colors: Control the blending of ROI colors and displayed values Listbox Select ROIS to be displayed/filtered
