With the cursor out of the window ImGui has no place for it, and the ray
under it came out as NaN: the zoom put the camera there for good and the
next look at the ground under the cursor aborted. The wheel is left
alone then, and the ground isn't asked for a point which isn't one. The
self-test gets leave, the cursor taken out of the window.
The ends' budget of a curve too big for its leg lowered the scale of both
vertices beside it, a straight one too, which has no tangents to ask:
with no transitions the empty function was called and threw
bad_function_call, with transitions the vertex got a false warning of a
reduced R. Straight vertices are left out of the scaling.
The tiles are given to the gpu straight from memory; the garbage sweep
released them like the ones read from files and they came back as the
grey stub until made again. They're kept now, and a new texture name
clears the cache of the bound units.
The lift moved the models of the includes it remade a moment later, so
the cells kept the old ones after they were destroyed and the next look
at the ground there (a zoom) crashed. They stay as they are now, and the
models already waiting to be destroyed are skipped too. The self-test
gets danglers, which counts the models the cells hold past their end.
The terrain model was made once around the camera when a new scenery
took it; tracks laid on past it went over nothing. While a track is laid
or dragged out, the chunks missing within 400 m of the cursor are now
made from the model too, the nearest first, in a scenery with the
heightmap terrain placed on the map. The formations aren't made anew
after such chunks. A chip in the terrain panel turns it off.
A touchpad under Wayland sends a scroll as many fractions of a notch.
Shift+wheel took each of them for a step and went round the shapes of
the laid track, the joins and the connections several times in one
swipe; now the fractions are gathered into whole notches and a gesture
moves such a choice one step. Ctrl+wheel steps the radius once a notch.
The 3D zoom measured to the level 0 when nothing was under the cursor,
which in a scenery on the terrain model lies far below or kilometres
ahead, so a light swipe at the horizon flew the camera away. It
measures to the ground under the camera now, backs away by no more than
four heights of the camera over it, and takes at most two notches at a
time. Self-test laystate tells the shape, the radius and the camera.
