LifeViewer/Known bugs/Not fixable

Jump to navigation Jump to search

This page serves as an archive of known issues of LifeViewer which cannot be fixed due to limitations of the hardware and/or browser LifeViewer is being run on.

Identify

  • The period map generated by Identify can sometimes appear blurry.
    • This is caused by the browser scaling the LifeViewer window.
    • This only occurs when "Scale" (see Help > Info) is at a non-integer value.
    • This occurs when the bounding box of the oscillator in question is not large enough for the "no grid, but with a thick border" period map style to be used, but is too thick for the "with a grid" style to be displayed without being slightly rescaled, introducing undesirable blurring.
    • More information on this issue, as well as an adjustable test case, can be found here: https://conwaylife.com/forums/viewtopic.php?p=158135#p158135

Rendering

  • On hexagonal and triangular grids, cells of the exact same or similar colors directly adjacent to each other may render small gaps between each other, which are most visible for non-integer zoom levels.
    • These may be incredibly subtle depending on the hardware and software used - it may be advisable to take a screenshot and paste it into an image editor and flood fill in order to reveal these borders.

  • For objects made out of triangles, small lumps may protrude from straight surfaces, especially for non-integer zoom levels. This may be difficult to see, as the lumps stay roughly the same size regardless of zoom level.

  • Hexagonal and triangular cells can appear to slightly overlap with each other visually when the pattern is running. This does not happen to anywhere near the same extent for square cells or those displayed as rectangular.

Interestingly, [R]Super reverses this; compared to [R]Standard and [R]History, hexagons in the same setup can appear disjoint.
