15aa7d94 06/08/2017 01:53 PM Leszek Koltunski

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

Simplify drawRecursive

c2c08950 03/02/2017 12:04 AM Leszek Koltunski

simplify blitPriv()

c1e24646 03/01/2017 11:02 PM Leszek Koltunski

Introduce Effects.blitPriv() (faster than previous drawNoEffectsPriv)

ad33f883 03/01/2017 05:48 PM Leszek Koltunski

Minor

03cb451d 03/01/2017 12:06 PM Leszek Koltunski

9d5bb851 01/25/2017 12:56 AM Leszek Koltunski

minor.

5ccafcca 01/24/2017 05:35 PM Leszek Koltunski

Separable Box blur fully works now!

0d81d0fb 01/24/2017 02:07 PM Leszek Koltunski

Separable Box blur (almost) works.

f1d5ea12 01/24/2017 12:51 AM Leszek Koltunski

Small progress with Blur.

2e7ad49f 01/21/2017 12:25 AM Leszek Koltunski

Define float precision in Vertex Shaders to the same like in Fragment Shaders.

667a1ad9 01/19/2017 12:28 AM Leszek Koltunski

improve Postprocessing; new icon; minor things.

c90b9e01 01/18/2017 04:01 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

progress with Postprocessing.

4c1dd6e9 12/17/2016 01:20 AM Leszek Koltunski

Beginnings of support for postprocessing Effects.

fe3cee39 10/21/2016 09:42 PM Leszek Koltunski

1. Workaround for th issue that my shitty Nexus 4 crashes while compiling the vertext shader (actually the wave function)
2. Improvements to the Dynamics app

ea16dc89 10/21/2016 01:44 PM Leszek Koltunski

minor stuff

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.

a7067deb 09/15/2016 09:04 PM Leszek Koltunski

small improvements in DISTORT

9ea4f88f 08/31/2016 10:39 PM Leszek Koltunski

Better normals in DISTORT

815869cb 08/30/2016 04:55 PM Leszek Koltunski

Vertex positions fully 3D now. Remaining: normals!

02ef26bc 08/30/2016 04:29 PM Leszek Koltunski

Preparation to make the WAVE effect fully 3D

6ddda212 08/29/2016 09:34 PM Leszek Koltunski

Adjustments for EffectQueueVertex.postprocess()

9b82becd 08/29/2016 06:32 PM Leszek Koltunski

Improvements for WAVE

4fde55a0 08/29/2016 04:51 PM Leszek Koltunski

Beginnings of the WAVE effect.

20af7b69 08/24/2016 09:31 PM Leszek Koltunski

Correct an important bug in the vertex shader.

b = 1/a if a!=0, 1 otherwise was incorrectly computed as b = 1.0 / (a+1.0-sign(a)). This, when 0<a<2^-24, suffers from 'round-off error': then a+1.0 = 1.0 (sic!) thus b = 1/0 !.

Correct way: b = 1.0 / ( a - (sign(a)-1.0) )

77fcb24d 08/11/2016 10:41 PM Leszek Koltunski

Fix for Bug #17: Regions of Fragment Effects migrate.

Fix is: don't send vertex position and the Fragment Effect region to the fragment shader already multiplied by the ModelView matrix (that introduces the imprecise interpolation because of the projection effect) but simply send both of them in local coords.

42e08626 08/09/2016 02:22 PM Leszek Koltunski

Remove the MACROBLOCK Effect altogether.

ff8ad0a7 07/20/2016 11:11 PM Leszek Koltunski

Fix for Bug #16: When rotated at an angle, surfaces get increasingly transparent.

This also fixes the saturation, chroma, alpha + contrast effects, while completely breaking macroblocks :)

30925500 07/17/2016 09:27 PM Leszek Koltunski

Fix for Bug #18: DISTORT effect: disappearing triangles

9420f2fe 07/16/2016 11:14 PM Leszek Koltunski

Fix for Bug 19: SWIRL effect: mess if Center out of Region.

ffbf279e 06/30/2016 01:06 PM Leszek Koltunski

revert latest changes to the fragment shader.
small things in DistortedObjects.

2e75bd79 06/29/2016 11:53 PM Leszek Koltunski

some improvements for the way we test DistortedObjects.

4018b3b7 06/29/2016 08:57 PM Leszek Koltunski

fix fragment effects :)

2dacdeb2 06/29/2016 04:15 PM Leszek Koltunski

remove the 'Color' vertex attribute.

8cefe6a3 06/28/2016 03:58 PM Leszek Koltunski

switch precision to low in fragment shader

cd174a64 06/28/2016 01:01 PM Leszek Koltunski

Make the 'deform' effect continuous when 'center' point passes through (0,0) i.e. middle of the Object.

369ee56a 06/27/2016 10:57 PM Leszek Koltunski

fix in vertex shader

7c227ed2 06/27/2016 12:35 PM Leszek Koltunski

Bugfix in vertex shader (vertices were shot into outer space if P==S, i.e. if center point was exactly equal to the vertex being computed)

341c803d 06/27/2016 12:00 PM Leszek Koltunski

Progress with Vertex3D

0318e7e3 06/24/2016 11:05 AM Leszek Koltunski

Important bugfix in the vertex shader: there was division by 0 in case Center point was on the edge of the Object, resulting in some vertices being shot into outer space.

0df17fad 06/21/2016 01:02 PM Leszek Koltunski

- Javadoc for EffectNames
- make Matrix effects consistent with the rest (center of effect as last parameter!)
- bugfix for yesterday's bugfix (we only want to send 'EFFECT_REMOVED' messages if it was really the Application that called 'abortAll' and not when we are cleaning up everything)

f2fe7e28 06/16/2016 04:21 PM Leszek Koltunski

Major push towards simplifying DistortedObject's public API.
Beginning of work on VERTEX Effects - does not compile ATM!

2fce34f4 06/16/2016 01:50 PM Leszek Koltunski

Major push towards simplifying DistortedObject's public API.
All Fragment effects are using the new API - the 'DataND' marker interfaces.

d333eb6b 06/14/2016 04:24 PM Leszek Koltunski
