BuddhaShader/BuddhaTest/include, 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/include?h=feature/06-better-preview 2018-03-21T22:16:20Z 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... 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 Adjust default workgroup sizes to better match recommended values. 2018-03-17T21:39:45Z Andreas Grois andi@grois.info 2018-03-17T21:39:45Z urn:sha1:f3f67518d7eb74c868b523851ec482cd2177c3ce AMD recommends a local workgroup size of 256. Correct line endings. 2018-03-17T16:51:19Z Andreas Grois andi@grois.info 2018-03-17T16:51:19Z urn:sha1:b05e87dc5004f5badc02508570ddc55f31b451cc Fix endless loop in shader and make framerate adaptive 2018-03-15T21:34:52Z Andreas Grois andi@grois.info 2018-03-15T21:34:52Z urn:sha1:bb9b7d23a1ca8e2afa8c8636d7312adc700d9a34 It seems forcing points outside the cardioid and bulb with a bad random generator can take really long... Also, now framerate adjusts based on time it takes to render frames. Prevent even more waiting by storing a more complete state 2018-03-15T07:35:32Z Andreas Grois andi@grois.info 2018-03-15T07:35:32Z urn:sha1:85e8b5336debbbe7a88a8016ba8922e06386de21 First commit with compute pausability 2018-03-14T21:39:06Z Andreas Grois andi@grois.info 2018-03-14T21:39:06Z urn:sha1:a350181f2c15feb072c2edf5d0c41965936f1948 Split buffer in three, one per color (as OpenGL guarantees that one can at least have 8 SSBOs), to allow three times larger images. Also make it possible to ignore maximum buffer size reported by the driver. 2018-03-11T20:27:11Z Andreas Grois andi@grois.info 2018-03-11T20:27:11Z urn:sha1:627aa610fc93398ac51129096ce8fb30731af341 The maximum buffer size limitation is rather strict on radeonsi, so I decided to split the buffer in three, effectively increasing the maximum image size by a factor of three. While doing so I realized that at least on radeonsi the reported maximum buffer size seems to be off. For this reason I added a new command line switch, that allows to ignore the maximum buffer size check. For those curious: radeonsi reports a maximum buffer size of 128 MB, but I had no problems when using three buffers of 1098 MB each. Prepare install script, and make shader loading work from PREFIX/share/... 2018-03-10T19:34:35Z Andreas Grois andi@grois.info 2018-03-10T19:34:35Z urn:sha1:2759a3f45b5cd095bb79eff77b35978c8f8069c6 Add command line parsing 2018-03-10T17:48:52Z Andreas Grois andi@grois.info 2018-03-10T17:48:52Z urn:sha1:5127d05dfdc877b0fc06e6ec228cfef09b98539a
