Hi Hans,
I recompiled the reduced-range gyroid test (after changing the ranges
from |-2pi … 2pi| to |-pi … pi| and adding the vector mesh as you
suggested) and reopened the resulting PDF in Acrobat.
The grey veil I initially saw was not persistent and was apparently an
artefact of the preview renderer. The newly generated PDF displays the
coloured gyroid correctly in Acrobat, without any grey opaque overlay.
The cached compilation took:
MetaPost: 0.014 seconds
ConTeXt runtime: 0.271 seconds
Acrobat remains responsive with the vector mesh enabled, although the
0.05 pt mesh lines are naturally very difficult to distinguish at
ordinary zoom levels.
Sure, but this vector mesh is only for tracing, so not really used in
documents. (With \nopdfcompression you can check how much of the pdf
file is consumed by this.)
So the PDF viewer stress test appears successful here (Adobe Acrobat Pro
64-bit, version 2026.001.21691, on Windows 11.).
Good. Btw, if you feed a setup (say implicit) into gemini and ask for
there examples you get nice ones in the proper syntax.
