In an attempt to contain the flashes on Mali GPU, re-structure the post-processing FBOs from 1 FBO with 2 color attachments + combined depth-stencil to 2 separate FBOs sharing a depth-stencil texture.

Result: this appears to make the flashes slightly worse.

2aef1f4d 05/31/2018 12:33 PM Leszek Koltunski

OIT: fixes for Mali: fix a broken loop in the oitRender fragment shader that resulted in flashing.

344ac0e4 05/30/2018 02:22 PM Leszek Koltunski

OIT: fix for 'out of memory' crash on Mali GPUs.

~The thing still does not fully work there - there are still strange flashes in apps that innvolve OIT, for example in 'Triblur'.

5fdae11d 05/23/2018 12:56 PM Leszek Koltunski

OIT: more fixes

c207da02 05/22/2018 03:48 PM Leszek Koltunski

OIT: fixes. Everything looks correct now except for the curious return of the 'dancing lower-left corner' small glitch in the 'Transparency' app.

90eb5f53 05/22/2018 01:26 PM Leszek Koltunski

OIT: correction for blending in Pass4

33f59f22 05/21/2018 05:17 PM Leszek Koltunski

OIT: move towards 4 passes ( clear - build - collapse - render )

bbe3283b 05/18/2018 02:13 PM Leszek Koltunski

correct oitRender again: we need to disable stencil reading and writing and restore after

c8d70463 05/18/2018 01:58 PM Leszek Koltunski

correct oitRenddr again; correct coming to paused state (we could crash)

e92f191a 05/18/2018 12:06 PM Leszek Koltunski

Make sure we don't create a feedback loop in oitRender

c41d046c 05/17/2018 08:16 PM Leszek Koltunski

Make sure we don't create a feedback loop in oitRender

9ab3b712 05/17/2018 04:10 PM Leszek Koltunski

Make us read only the DEPTH part of a DEPTH24_STENCIL8 attachment.

56c6ca24 05/10/2018 12:30 PM Leszek Koltunski

OIT: lots of progress on all fronts. Still a few bugs to solve though!

27aefee6 05/03/2018 04:19 PM Leszek Koltunski

OIT: clear the postprocessing buffer with transparent white.

78e89fb5 05/03/2018 03:10 PM Leszek Koltunski

Properly recreate the Atomic and LinkedList buffers onPause.
We have to discard all alpha==0.0 pixels during OIT Pass1.

b36613d8 05/03/2018 12:19 AM Leszek Koltunski

small correction for blending OIT colors.

c92d84ec 05/01/2018 11:21 PM Leszek Koltunski

minor.

375b3950 05/01/2018 11:19 PM Leszek Koltunski

OIT: something starts working ('Blur' and 'Multiblur' work, 'Triblur' and 'Transparency' do not)

c731c612 05/01/2018 09:07 PM Leszek Koltunski

Fix the 'OIT' artefacts.

Disable blending during postprocessing.

9455da17 04/09/2018 12:03 PM Leszek Koltunski

Fix for bug #28: looks of the borders of a blurred object depend on if the object is the first in the postprocessing bucket.

ae2802b1 04/08/2018 09:07 PM Leszek Koltunski

Postprocessing buffers mBuffer[] are now shared among all postprocessing operations. This saves a lot of memory, but also means that when doing each particular postprocessing, the textures backing up the mBuffer might be too large. We need to fix two things here: when outputting to those too large textures, we need to adjust the Viewport, and when binding those too large textures as input - we need to adjust the TexCoords to compensate....

79e354b0 04/06/2018 11:28 PM Leszek Koltunski

Improve the 'PostprocessTree' app. Shows bugs in postprocessing.

b0f04e72 04/06/2018 02:31 PM Leszek Koltunski

Simplify postprocessing buffers.

ce154014 04/06/2018 02:02 PM Leszek Koltunski

Make the postprocessing buffers static.

61441ce2 04/06/2018 01:28 PM Leszek Koltunski

A little progress making the postprocessing buffers static.

a4b182d4 04/06/2018 12:21 PM Leszek Koltunski

Introduce possibility that an OutputSurface is backed up by a larger texture than necessary and the 'cloneSize()' method.

3493ef61 04/05/2018 10:20 AM Leszek Koltunski

Improve Blur (boundaries should be more white than black)

e136346d 04/04/2018 02:01 PM Leszek Koltunski

New 'Triblur' testapp.

Shows that the Blur effect doesn't fully work (probably it is the 'blitWithDepth' function which needs to be corrected)

2faad666 04/02/2018 10:15 PM Leszek Koltunski

SSBO: now we have a more-or-less correct running average of the count of transparent fragments over the last few frames.

df4d7edc 03/29/2018 03:58 PM Leszek Koltunski

SSBO: correct various things.

c14e495b 03/28/2018 11:36 PM Leszek Koltunski

SSBO: zero out the per-surface transparent fragment counter only when setting the surface as output for the first time in the frame.

51a3cbab 03/28/2018 10:33 PM Leszek Koltunski

SSBO: handle the fact that we might run out of space in our SSBO if we keep creating new Surfaces.

8a57da61 03/28/2018 09:14 PM Leszek Koltunski

SSBO: counting of transparent fragments more or less works now. Still the counters are zeroed out in the wrong place - every time we start rendering something to a given Surface, rather than once per frame.

27cd6b98 03/28/2018 08:29 PM Leszek Koltunski

SSBO: more and more works...

66ace7f5 03/28/2018 05:34 PM Leszek Koltunski

SSBO: fix problems with endianness.

2ab60f72 03/28/2018 01:58 PM Leszek Koltunski

SSBO: something is working already, although we still get the 4 bytes back from the shader in reverse order ( so '17'=0x00000011 written by the shader becomes '285212672 = 0x11000000' )

12f45260 03/27/2018 07:56 PM Leszek Koltunski

First try at the SSBO (doesn't work - reads in the application don't pick up changes in the shader; crashes.

e6519ac8 03/27/2018 12:51 PM Leszek Koltunski

Up library requirements to OpenGL ES 3.1 (needed for the upcoming GL_SHADER_STORAGE_BUFFER)

7d0ce619 03/27/2018 12:21 PM Leszek Koltunski

New Object Counter class - to count OutputSurfaces lazy way, but keep the counters small (reuse)

a1003b17 03/23/2018 12:28 PM Leszek Koltunski
