Extractions: The Raster3D molecular graphics package consists of a core program render and a number of ancillary programs which read atomic coordinates from Brookhaven PDB files to produce scene descriptions for input to render. Raster3D can also render images composed using other programs such as Molscript and XtalView Index Programs in the Raster3D package Hints for composing pictures Raster3D uses a fast Z-buffer algorithm to produce high quality pixel images featuring one shadowing light source, additional non-shadowing light sources, specular highlighting, transparency, and Phong shaded surfaces. Output is in the form of a pixel image with 24 bits of color information per pixel. Raster3D does not depend on graphics hardware. Four common image output formats are supported: AVS, JPEG, TIFF, and SGI libimage. To actually view or manipulate the images produced, you must also have installed an image viewing package (e.g. John Cristy's ImageMagick or the SGI libimage utilities). The Raster3D rendering program can be integrated with ImageMagick to expand the flexibility of output formats and interactive use. Ancillary programs are provided for the generation of object descriptions based on atomic coordinates stored in Brookhaven PDB format. Although the rendering program is not specific to molecular graphics, Raster3D is not intended as a general purpose ray-tracing program. Some of the algorithms used have been chosen for speed rather than generality; that is, they happen to work well for the types of images the program is intended for, but may produce odd results if used for very different types of image.
Create It ~101; Basic HTML-background Color Thalia's color composing Engine http//www.sci.kun.nl/cgibin-thalia/color/composeAnother site with an ability to choose and see the colors as they will http://www.geocities.com/SiliconValley/6658/bgcolor.html
Extractions: Background Color The background color of your page can be just about any color you want. It can be midnight black or forest green, depending on your taste. You will create with great a yellow background. "So," you may be thinking, "which colors can I use? If I type: "will the browser know I'm looking for a grayish white?" The short answer is: No. Only a limited number of colors can be specified by name (snowslush isn't one of them), and different browsers recognize different sets of colors. So if you want to be precise about your background , you'll want to replace the name of the color, with a hexadecimal code . So your HTML would look something like this: Notice all those "f"s in the code? Well, that's how one says "white" in hexadecimal. The "ffffff" represents the RGB value of white, translated into hexadecimal. Any color that can be displayed on a monitor can be described by its RGB value - its relative amounts of red, green, and blue (each of which is expressed as a two-digit number, such as 51 or 14 or 00). Now, if you don't want to bother with calculating those numbers, you can just go color shopping:
Raster3D Package For Photorealistic Molecular Graphics Output is in the form of a pixel image with 24 bits of color information perpixel. Raster3D does not depend on graphics hardware for operation. http://www-structure.bio.purdue.edu/docs/raster3d/raster3d.html
Extractions: The Raster3D molecular graphics package consists of a core program render and a number of ancillary programs which produce input files for rendering from Brookhaven PDB files of atomic coordinates. Raster3D can also render images composed using version 1.4 or later of Molscript Individual programs in the Raster3D package Hints for composing pictures Raster3D uses a fast Z-buffer algorithm to produce high quality pixel images featuring two light sources, specular highlighting, Phong shaded surfaces, and shadowing. Output is in the form of a pixel image with 24 bits of color information per pixel. Raster3D does not depend on graphics hardware for operation. Four image output formats are supported: AVS, TIFF, SGI libimage, and a private format which is backwards-compatible with earlier versions of Raster3D. To actually view or manipulate the images produced, you must also have installed an image viewing package (e.g. John Cristy's ImageMagick or the SGI libimage utilities). An alternate version of the rendering may be built which directly outputs JPEG images [only]. Ancillary programs are provided for the generation of object descriptions based on atomic coordinates stored in Brookhaven PDB format. Although the rendering program is not specific to molecular graphics, Raster3D is not intended as a general purpose ray-tracing program. Some of the algorithms used have been chosen for speed rather than generality; that is, they happen to work well for the types of images the program is intended for, but may produce odd results if used for very different types of image.
Web Style can be directly manipulated in composing page layouts choice for a default backgroundcolor to define to provide informative alternative text for your graphics. http://www.upenn.edu/computing/web/webdev/style/page/visualgra.html
Extractions: The way you design with pictures depends on the nature of the information you want to present and the needs and interests of your audience. The overriding fact of graphics on the Web is that the larger the picturelarge in square inches, number of colors, or unneeded resolutionthe larger the file size and the slower to load. Viewers who mainly want textual information in a hurry will resent graphics that seem empty and merely decorative. Other viewers may be willing to exercise great patience to receive images of compelling beauty or dramatic illustrative power. However you use graphics, you owe it to your viewers to make the files as fast to load as your goals permit. The following technical notes include techniques for doing this as well as other considerations. 1. File formats: Learn to work with both GIF and JPEG. For the present, choose GIF or JPEG based on the combination of characteristics that best suits your requirements and your image-processing software. 2. Use inline graphics except for special purposes. A graphic element placed in an HTML file so that it displays in linear sequence among with the other page elements is called an "inline" graphic. To display it properly, the browser must be capable of recognizing and displaying the graphic's file format in inline form. Graphic files that a browser cannot display in line must be handed off to a "helper application" for display, which interrupts the continuity of the viewer's experience of the page. Inline graphics can be directly manipulated in composing page layouts, and the trend is for browsers to accommodate more types of inline formats.

Extractions: olor can be a used in many ways to help with the design of your web site. It can be used as a theme that unites your pages into a unified design or as a means of attracting attention. In the print world dealing with color can be very expensive. The nice thing about color on the web, as it relates to the print world, is that it is no more expensive to produce than black and white. This is probably the single biggest advantage web design has over print design. As HTML becomes more advanced, some doors have opened up to the use of color. We now have the advantage of coloring our background, text, links, etc. The problem with color as it relates to the web, however, is that different monitors interpret color differently. One tool in dealing with this problem is the CLUT palette which is explained on the graphics page of this site. Although these difficulties can be limiting, one can still work effectively using color to its fullest design potential.
