2e15fab651 Doubles down on <cX> over <X.h> for C includes, and usage of the namespace for those types and functions. 2017-11-11 15:28:40 -05:00

ce78d9d12c Introduces buffer alignment when writing to textures.
To avoid cross-boundary writes and hopefully to eke out a little better performance.

8ccec37a4b Eliminated a further potential cause of texture/geometry mismatch: the texture retain succeeded but then there wasn't room for geometry. 2017-07-09 19:11:38 -04:00

a25c2fd6b5 Got more explicit about what the thinking is here re: multiple sources of action. 2017-07-09 17:54:26 -04:00

ee1a9a4781 Eliminates attempts cleverly to shuffle unsubmitted runs, because no mechanism exists to stop them overwriting previously-submitted-but-not-yet-flushed runs. Which implies that the buffer must be fully circular. The cost of which is sometimes having to make two calls to glTexSubImage2D. Also added some TODOs, and a means for reporting when a retain_latest is ineffective, in which situation it would be inappropriate to attempt to generate correlated geometry 2017-07-09 17:50:22 -04:00

2f90f35478 Ensured the same write area can be submitted multiple times — this is actively used if a run of data overlaps a flywheel-suggested sync. Which nullifies the idea of not having a write area in the barrel, at least as soon as any one has been allocated. 2017-07-07 23:37:44 -04:00

bfbe12b94b Made an attempt further to tie geometry and texture generation fully together, removing the assumption that the caller will achieve one-to-one calling. 2017-07-07 22:25:05 -04:00
Thomas Harte
427175b9c0 Added an extra flag to avoid potential race condition on is_full_, being reset from the background despite a write area not having been allocated. 2017-01-29 16:13:28 -05:00

5216dda675 Added some brief extra exposition to the texture builder, cut all internal tex_x/y and source_divider stuff from the CRT. 2016-12-06 19:08:55 -05:00

0fee8096c1 Made an attempt to shuffle the texture builder to a similar flush/submit pattern as the input builder. Don't care about thread safety yet, as it's obvious I'm going to need to move that back up to the CRT. 2016-12-06 07:24:07 -05:00

0edc043378 Started introducing an extra layer of indirection so as to be able to bind the texture builder to the same flush and submit patern as the array builder. 2016-12-03 20:47:19 -05:00

1f91d29434 Progressed to usage of an array builder and a texture builder up to the point of a successful build. 2016-11-17 12:26:04 +08:00

edeafd4d94 Wait, OpenGL textures go the other way. 2016-11-16 23:14:15 +08:00

6ac20e0066 Pushed responsibility for submitting texture contents up to the texture builder, simplifying the interface. 2016-11-16 23:13:06 +08:00

5c5e44874f Even better: why include the 'Input' prefix when there's only one? 2016-11-16 22:57:17 +08:00
