BuddhaShader/BuddhaTest/src, branch feature/06-better-preview First steps with OpenGL: A compute shader that renders a BuddhaBrot to an SSBO. Can also save the result to PNG for future viewing pleasure. https://git.grois.info/BuddhaShader/atom/BuddhaTest/src?h=feature/06-better-preview 2018-03-22T22:32:54Z Fix compiler warning in MSVC 2018-03-22T22:32:54Z Andreas Grois andi@grois.info 2018-03-22T22:32:54Z urn:sha1:7bfd42aca8b749e736490222048e4bea7e965b44 Make preview use color scale and gamma 2018-03-22T22:23:30Z Andreas Grois andi@grois.info 2018-03-22T22:23:30Z urn:sha1:81863349bfc7fede772eac9b6fd8024f49380e42 Get occupancy back up good by exploiting shared memory. 2018-03-22T21:52:44Z Andreas Grois andi@grois.info 2018-03-22T21:52:44Z urn:sha1:e45b39dc2ebb76bc079677b1d186b6a5109d1a5b Initial commit for better brightness. 2018-03-21T23:05:59Z Andreas Grois andi@grois.info 2018-03-21T23:05:59Z urn:sha1:fa76d77be61ad3f0b295a87236e74f150597751f Needs more work, uses too many VGPRs. Also, maybe work on a single shared variable? Initial benchmark support. 2018-03-21T22:16:20Z Andreas Grois andi@grois.info 2018-03-21T22:16:20Z urn:sha1:cca3254becdf793b9335a1f21bcda2c0909f4d1a Finally no more manual stopwatch usage... Fix build error regarding debug log clock 2018-03-18T21:37:49Z Andreas Grois andi@grois.info 2018-03-18T21:37:49Z urn:sha1:0c7b45b4e84aa197ada7391007f7d1610c92476c Undo splitting of buffers in three. Makes buffer access much faster 2018-03-18T20:11:39Z Andreas Grois andi@grois.info 2018-03-18T20:11:39Z urn:sha1:dc193156a82a80cc8d2321cf065019035855516f Not kidding here. For the default parameters this increased the maximum pixel brightness in the image by a factor of 2.25. This has the drawback that the maximum possible image size got reduced, but hey, there's a command line switch to ignore all size limits ;-) Move totaliterations calculation to CPU. This frees 4 VGPRs. 2018-03-18T19:45:26Z Andreas Grois andi@grois.info 2018-03-18T19:45:26Z urn:sha1:db2ea861c688aadf59fc35ff6cfca69149a1a94c Now the code is back to the limit of 32 VGPRs without the need to directly operate on the state buffer. This means that now it's bound by memory access. Undo change to directly work on buffer. Causes about 30% slowdown... 2018-03-18T16:19:33Z Andreas Grois andi@grois.info 2018-03-18T16:19:33Z urn:sha1:c6ba30d76aca396ce5a3975f4625e05e8cf915ee Add option to skip short orbits. Add option to print debug output. 2018-03-18T15:24:50Z Andreas Grois andi@grois.info 2018-03-18T15:24:50Z urn:sha1:385dd0dcf8fd003db604355341b00baa1fe1c1a0
