7.5 Color settings

Thanks to this dialog box that can be visualized selecting View Color Settings, it's possible to change some interesting color parameters for a nice view.


7.5.1 Background settings

Background settings

Clicking the Background color box, you can change the background color. As a possible application of this feature, you can change the background color from black to white in order to make an hard copy of the screen. Changing Logo gadget, you can superimpose the VEGA ZZ logo on the screen, placing at Top left, Top center, Top right, Center left, Centered, Center right, Bottom left, Bottom center and Bottom right of the workspace.
The SkyVision system allows you to apply 3D landscapes or complex color gradients to the scene. More in detail, it places the scene at the center of a cube (skybox) with faces textured with the landscape as in a 3D video game. To generate the ambient, you must provide to VEGA ZZ one of these inputs:

  • Six pictures in JPEG format (one for each face)
    The resolution of the images must have at least the size of 128x128, but too large images (more than 2048x2048) aren't recommended because require a lot of graphic memory and reduce the rendering performances. The six image files must be named according the following rule:  given landscape as skybox name, the six faces must be named: landscape_back.jpg, landscape_bottom.jpg, landscape_front.jpg, landscape_left.jpg, landscape_right.jpg and landscape_top.jpg.
  • One equirectangular 360 picture in JPEG format
    This kind of picture can be taken with panoramic cameras (e.g. LG 105R, Insta 360, Samsung Gear, etc.) and can be used as skybox and 3D equirectangular pictures (top/bottom). It is automatically detected when the picture has the 1:2 aspect ratio.
  • One equirectangular 360 3D picture in JPEG format
    As above, but it includes 3D data in top/bottom format. It is automatically detected when the picture has the 1:1 aspect ratio. You can appreciate the amazing 3D effect only if VEGA ZZ is rendering in stereo mode. For best results, you can use a 3D headset, selecting OpenVR as stereo mode in the View settings window.
  • One color gradient file in CSV format
    Color gradients are stored as a simple CSV file in which the color of each cube vertex is stored in RGB format. Each color component can assume a value from 0 to 255.
    Here is an example of CSV file:

The first line is the header, followed by 8 optional lines in which the vertex ID and the color components are present. The could be not necessary ordered in ascending order of vertex and the file can be edited by a text editor or a spreadsheet program


All these files The landscape can be adjusted in the scene changing the position (X offset and Y offset) and the orientation (X rotation, Y rotation and Z rotation). When you click the dot buttons, the parameters are reverted to default.


7.5.2 Atom settings

Atom settingsIn this tab, you can change the color scheme used when you select View Color By atom in the main menu. It's also possible to change the color of the generic atom labels and of the unknown potential labels (see Labels box). Clicking Default, all colors are reverted to default.


7.5.3 Residue settings

Residue settingsIn Residues tab, you can change the color scheme used when you select View Color By residue in the main menu. Clicking Default, the color scheme is reverted to default.


7.5.4 Monitor settings

Monitor settingsIn Monitor tab, you can set the color and the transparency (0 = full transparent, 255 = full opaque) of the monitors shown when you measure angles, bumps, distances, torsions and angles between two planes.  Clicking Default, the colors and the transparencies are reverted to default.



7.5.5 Other settings

H-bonds settingsIn this tab, you can change the color of the H-bond acceptors, H-bond donors and non H-bond involved atoms. Moreover, you can change the color of flexible and rigid bonds.
