I Like Trains/test, branch mainThe I Like Trains gamehttp://git.randomdan.homeip.net/repo/ilt/atom?h=main2026-04-01T19:21:23ZHave Renderable manage all instance lights2026-04-01T19:21:23ZDan Goodliffedan@randomdan.homeip.net2026-04-01T19:21:23Zurn:sha1:30fcb8bce7b60b6754a0d35f2f15b627d0fba4cb
Spot and point lights now existing in Renderable, the vertex data
contains the owning parent object's index in CommonLocationData, the
render step is just a single draw call.
Add helper to Decompose a member pointer2026-04-01T13:21:10ZDan Goodliffedan.goodliffe@octal.co.uk2026-04-01T13:21:10Zurn:sha1:6635cee143eb4cf3882bac519b8c12b83b62de62Use a single buffer for the location/rotation data of all renderable objects2026-03-30T23:37:24ZDan Goodliffedan.goodliffe@octal.co.uk2026-03-30T12:04:36Zurn:sha1:fb78c88576d9fed90ee69dfa35a9fbd3179ff486
Removes the BufferedLocation and BufferedLocationUpdater mess.
Note: appears to break bogie rendering in asset factory test only, same
symptom as broken network render test? (out of date buffer data)
Improve light approximations in LightDirection2026-03-26T20:46:58ZDan Goodliffedan@randomdan.homeip.net2026-03-26T20:46:58Zurn:sha1:947319e25e49027d77543ae5c6f6c01d451a8926
Twilight replaces astronomical twilight to give a longer fade. Astronomical
twilight is only the darkest part of twilight, which we had skipped right to.
Fixes directional light amount to only be affected by the sun's passing
below th horizon, not it's whole height above it.
Adds a rough approximation of the amount of atmosphere scattering of
directional light (I made this calculation up)
glAllocator revamp2026-03-15T02:15:41ZDan Goodliffedan@randomdan.homeip.net2026-03-15T02:15:41Zurn:sha1:200b96d780598fe5ec59f2fc7e2e3eb6ac69d0de
Remove the map of buffers, now a fat pointer containing the buffer's
name. This is accessible via the container's begin/end iterator. Move
the bulk of the logic out of the template, it's mostly void * from the
mapping anyway. Add allocate_at_least support.

Normalises the range of position information into the range 0-255 so the
resulting image is remotely useful.

glContainer is no longer required, as we can use std::vector with a
custom allocator which uses OpenGL buffers for storage. Minor irritation
is that the mapped buffers aren't guaranteed to be flushed in the tests,
so sometimes we're missing bits in a test render.
