There are two types of set options, those which assign user-specified values and those which act as on/off toggles.
Whether to give each newly opened model a different color; same as use new color... in the New Molecules preferences.• set bg_color color
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. Example: set bg_color white• set depth_cue
Whether to use depth-cueing, front-to-back shading of the scene.• set dc_color color
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 dc_start start
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.• set independent
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.• set light_quality mode
See also: cofr, focus, tile, Rotation
Which mode of lighting to use, normal or glossy. The glossy setting uses an Open GL shader to provide per-pixel lighting, which gives a glossy appearance, and angle-dependent transparency. Glossy lighting may not be supported by the graphics driver; Mac users should be aware that on a given machine, glossy lighting may be available in the Aqua version of Chimera but not the X11 version. With normal lighting, specular highlights are only calculated at triangle vertices and linearly interpolated across triangles, and transparent triangles do not appear more opaque when viewed edge-on as compared to face-on.• set projection mode
See also: Lighting, Shininess
Which mode of projection to use: perspective, which makes farther-away objects smaller, or orthographic, which does not.• set silhouette
Whether to show silhouette edges, outlines that emphasize borders and discontinuities.• set silhouette_color color
Sets the color of silhouette edges; color can be none or any color name that specifies a single color.• silhouette_width linewidth
Sets the linewidth of silhouette edges.• set subdivision value
Sets subdivision quality, 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.
