Whether to give each newly opened model a different color; same as use new color... in the New Molecules preferences.
See also: modelcolor

Sets the background color; color can be none or any color name that specifies a single color. Any transparency in the color will be ignored. Equivalent to background solid.

Whether to use depth-cueing, front-to-back shading of the scene.

Sets the depth-cueing color; color can be none or any color name that specifies a single color. Any transparency in the color will be ignored.

Set the position of the depth-cueing ramp. Depth-cueing shading increases linearly from start to end, each expressed as a position relative to the front (0.0) and back (1.0) global clipping planes.

Whether to use fullscreen mode, in which the graphics window fills the entire screen (available in Windows, Linux, and Mac-X11 versions of Chimera).

Whether to rotate models about their individual centers or a single collective center; set independent changes the center of rotation method to independent while ~set independent changes the center of rotation method to front center.
See the video mini-example. See also: cofr, focus, tile, Rotation

Set horizontal field of view in degrees (allowed range 0°< angle <180°).

Whether to make apparent transparency independent of the viewing angle. Otherwise, transparent triangles (forming objects as well as surfaces) will appear more opaque when viewed edged-on than when viewed face-on.

Set the maximum frame rate in Chimera to N frames per second (default 60). Although N is the target value, the actual rate may be lower depending on the rendering speed of the computer and the complexity of the scene. The actual frame rate can be reported in the status line using the accelerator rt (command ac rt).

Which mode of projection to use: perspective, which makes farther-away objects smaller, or orthographic, which does not.

Whether to show interactive shadows.

Whether to show silhouette edges, outlines that emphasize borders and discontinuities.

Sets the color of silhouette edges; color can be none (equivalent to black) or any color name that specifies a single color.

Sets the linewidth of silhouette edges.

Whether to render only the topmost layer of all transparent items. Showing only the topmost layer rather than all transparent layers simplifies the display and is recommended for de-emphasizing transparent parts.

Sets subdivision level, where a higher value increases the apparent smoothness of stick, ball-and-stick, sphere, and ribbon representations by increasing how many planar facets are used to approximate them.

By default, the fineness of faceting of stick, ball-and-stick, sphere, and ribbon representations is adjusted dynamically based on:

1. the subdivision parameter
2. the pixel width of the graphics window divided by the width of the view at the front clipping plane

Setting subdivisionPixels substitutes the specified static pixels-per-length for the second value above and suspends dynamic adjustment. This can enhance responsiveness to manual zooming (by precluding further subdivision calculations) and can speed up rendering by avoiding overly fine subdivisions that may occur with large windows and/or highly zoomed-in views. Setting pixels-per-length to zero or a negative value restores the dynamic subdivision behavior, as does ~set subdivisionPixels.
