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'.

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 )

b52f9415 05/11/2018 03:17 PM Leszek Koltunski

OIT: correct depth

7f30ed38 05/10/2018 03:11 PM Leszek Koltunski

OIT: more bugfixes

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

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

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.

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.

e029600f 04/27/2018 04:40 PM Leszek Koltunski

still debugging the OIT

2f35828c 04/26/2018 11:22 AM Leszek Koltunski

- remove counting of transparent pixels from main fragment shader
- remove debugs and tidy up
- some fixes for the Mali GPU

cee0369a 04/25/2018 03:26 PM Leszek Koltunski

Order Independent Transparency: debugging

47511918 04/25/2018 02:17 PM Leszek Koltunski

Order Independent Transparency: some progress

f89a986e 04/18/2018 02:37 PM Leszek Koltunski

Order Independent Transparency: some progress

8777ce17 04/17/2018 09:21 PM Leszek Koltunski

Order Independent Transparency. Does not work yet.

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....

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.

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...

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.

041b6dee 06/26/2017 03:44 PM Leszek Koltunski

Simplification in PostprocessEffects

7cd24173 06/20/2017 11:51 PM Leszek Koltunski

Move all the knowledge about Vertex and Fragment effects to their respective classes.

Progress with support for Effect classes.

2da9b250 05/30/2017 12:17 PM Leszek Koltunski

Beginnings of the GLOW unit test.

7170e4eb 05/24/2017 11:16 PM Leszek Koltunski

Move on to Stencil on both stages of the BLUR + separate 'blit with depth'.

This works wonders on Nexus 5X ( r=50 quality=HIGHIEST 1,4,8 cubes: 59.3,43.6,41.0 FPS! ) but it somehow fails to clear the DEPTH and STENCIL buffers on Nexus 4....

1d6d261e 05/24/2017 01:02 PM Leszek Koltunski

Move to a new way to detecting depth of postprocessing halos.
This switches off stenciling (hopefully temporarily!)

3fc9327a 05/11/2017 03:47 PM Leszek Koltunski

Use Transform Feedback to (optionally) display the Normal vectors.

604b2899 05/10/2017 12:56 PM Leszek Koltunski

Dynamic display of bounding rectangles (with coords computed by Vertex Shader and gotten with Transform Feedback) works now.

Major problem: the glMapBufferRange() slows doewn rendering in a major way. Multiblur's FPS:

Nexus5X : 35.4 before -> 12.6 after...

3e2376c4 05/09/2017 10:31 AM Leszek Koltunski

Make the Feedback APP work again.

135be991 05/09/2017 09:30 AM Leszek Koltunski

Revert "Progress with TransferFeedback app - introduce two modes: USEPOINTS 'true' or 'false'."

This reverts commit 21304c55380460c5882b789ea13eb00ffd9a686c.

dd7a5c7d 05/09/2017 09:30 AM Leszek Koltunski

Revert "This commit (and reading the OpenGL ES 3.0 spec) pretty conclusively proves that, sadly, Nexus 4's Transform Feedback implementation is incomplete (doesn't work with GL_TRIANGLES primitiveMode)"

This reverts commit 5ba19814852de1762e452662a13c4944792014a9.

f80337b5 05/09/2017 09:30 AM Leszek Koltunski

Revert "Some progress with Transform Feedback. Still many bugs all over."

This reverts commit 79921db22e4ff5a3b2e6e3466a39445f5607a695.

79921db2 05/05/2017 11:30 PM Leszek Koltunski

Some progress with Transform Feedback. Still many bugs all over.

5ba19814 05/05/2017 02:26 PM Leszek Koltunski

This commit (and reading the OpenGL ES 3.0 spec) pretty conclusively proves that, sadly, Nexus 4's Transform Feedback implementation is incomplete (doesn't work with GL_TRIANGLES primitiveMode)

21304c55 05/05/2017 12:17 AM Leszek Koltunski

Progress with TransferFeedback app - introduce two modes: USEPOINTS 'true' or 'false'.

On Nexus5X, it works with 'true' and 'false'. On Nexus 4, it works with 'true', but returns GL_INVALID_OPERATION with 'false'.

4782b4e6 05/02/2017 03:22 PM Leszek Koltunski

Progress with moving the Transform Feedback functionality from the APP to the library.

6e7c8721 04/26/2017 10:08 AM Leszek Koltunski

Simplifications.

fd2db957 04/21/2017 02:15 PM Leszek Koltunski

1) bugfix computing Gaussian BLUR kernel (for odd radii, the last offset was incorrectly computed)
2) introduce more advanced method of detecting BLUR halo (compute depths in a new way)

b7dba709 04/21/2017 10:04 AM Leszek Koltunski

Roll back the recent MIPMAP work.

f89f791a 04/19/2017 04:38 PM Leszek Koltunski

Preliminary support for MIPMAP levels of the postprocessing buffers. (doesn't work yet)

ed5bf324 03/31/2017 11:52 AM Leszek Koltunski

Merging blurred surfaces mostly ok now (blurred image still appears a bit shifted down for some reason)

1cbf4103 03/29/2017 12:55 PM Leszek Koltunski

Simplify shaders.

94f6d472 03/29/2017 11:05 AM Leszek Koltunski

Make it more flexible; now it can run almost all apps on OpenGL 2.0 contexts; OpenGL 3.0 ( with GLSL 3.00) required for POSTPROCESSING.

f2367b75 03/28/2017 12:26 PM Leszek Koltunski

Upgrade from GLSL 1.00 to GLSL 3.00 ES
Introduce separate BLUR1 and BLUR2 shaders, the second one marging (writing to gl_FragDepth still does not work)

a1b36fc8 03/16/2017 10:10 PM Leszek Koltunski

Simplify BLUR shader.

50642a86 03/03/2017 03:50 PM Leszek Koltunski

Progress with getting Mesh'es bounding rectangle. Still doesn't quite work yet (visible : 'Cubes' app with a 0111 Mesh)

2b942cd0 01/10/2017 09:24 PM Leszek Koltunski

Naive implementation of blur works now!

bfe2c61b 01/10/2017 10:27 AM Leszek Koltunski

Blurred image visible now!

47d838ca 01/06/2017 05:20 PM Leszek Koltunski

NUM_POSTPROCESS corectly #defined now.

c638c1b0 01/06/2017 01:46 PM Leszek Koltunski

Further progress with Postprocessing. Now the missing bits are:

- implement Distorted.getFBO()
- implement Distorted.clean()
- improve compilation of DistortedPrograms so that the NUM_POSTPROCESSING and names of POSTPROCESSING effects will be #defined.

d6e94c84 01/05/2017 02:23 AM Leszek Koltunski

350cc2f5 10/18/2016 11:19 AM Leszek Koltunski

Make the WAVE effect 5D (extra parameter 'offset')

d0c902b8 10/17/2016 03:04 PM Leszek Koltunski

swap the 2nd and the 3rd parameters in the WAVE effect and improve comments for the WAVE user API.

5b1c0f47 10/17/2016 02:12 PM Leszek Koltunski

Switch off the pre-compulting of sin and cos in CPU as it turns out that those two are single-instruction functions on any modern GPU ( http://www.gamedev.net/topic/322422-number-of-gpu-cycles-for-cos-and-sin-functions/ - link form 2005 ! )

f256e1a5 10/16/2016 10:37 PM Leszek Koltunski

Improve the comment the WAVE effect.

57297c51 10/16/2016 10:27 PM Leszek Koltunski

Correct one more issue with computation of WAVE.

c6ea3680 10/12/2016 09:50 PM Leszek Koltunski

Correct one issue with incorrect shadows in WAVE when V.z <0 .

73af5285 10/12/2016 12:29 AM Leszek Koltunski

Now we can add up the WAVE effect to others with smooth shading! Remaining issues:

- when angle A < 0, the shades are wrong
- sometimes (check with the 3D vertex & Fragment effects' app) we get black spots at seemingly random points. Looks like computational instability again.

06d71892 10/10/2016 10:15 PM Leszek Koltunski

Shades in the WAVE effect fully working, if the effect is the only one.

Remaining: combine the shades with other effects!

39b80df0 10/09/2016 10:42 PM Leszek Koltunski

Shades of the WAVE effect (almost!) working.
