e142ae77ca Imbuf types refactor.
ImBuf types were getting stored as bitflags in a 32bit integer which had
    already run out of space. Solved the problem by separating file type to
    an ftype enum, and file specific options to foptions.

749f346ce0 BGE: Add alpha to coverage render mode.
This patch add a new option for transparency meshes : Alpha to coverage, in the game setting panel in material.
The alpha to coverage request a multisample, the best is 8x but 4x and 2x can also give nice render.

00808eb39a Make OpenGL debug contexts a flag --debug-gpu instead of a compile time
option.

This makes sense, since contexts get created at runtime, there is little
reason to require recompilation for this.

Only works on linux currently, will be doing more OSs later

145d3540b3 Text effect strip for sequencer.
Is pretty much what it says :)
Easy subtitles for everyone!

Supports size, positioning,
a cheap shadow effect (probably will need more work),
and autocentering on x axis.

Now you can go wild with long spanish names
in your soap opera videos.

Will probably be refined as days go by,
but at least it's now ready for testing.

78411dc7d7 Fix T44755 set_value node output in node tree not properly converted to
color in GLSL

Issue here is that intermediate result was clipped as an optimization in
such nodes and thus not converted to the correct type properly. Now only
clip those values if types match.
This keeps both the optimization and the conversion. I looked at
converting uniform types always but it's more involved to compare types
at conversion time for such links because the type was getting
overridden during link duplication.

If you read the documentation, the numbers are not supposed to be exact
and also depend on the time when the call is made. The numbers can also
change quite quickly. It's only meant to give a rough measure of what is

c884ac28a7 3D Textures:
If we fail allocating a proxy texture don't fail, instead create a
smaller nearest filtered image to display in its place.

This can make viewing slow (it's an extra O^3 operation), but this will
probably help us render the tornado in 3D viewport in gooseberry and
still actually see something - despite the rendering taking longer.
I've added a debug print so we can know when this happens.

That was really crappy indeed. Now we have a separate API
for low level OpenGL programs, plus a nice interface for GPU, also
removes some GL calls from main code as a plus :)

The source for the programs is also moved to nice external .glsl files
(not sure which extension convention GPU assemply uses)

d5f1b9c222 Multi-View and Stereo 3D
Official Documentation:
http://www.blender.org/manual/render/workflows/multiview.html

Implemented Features
====================
Builtin Stereo Camera
* Convergence Mode
* Interocular Distance
* Convergence Distance
* Pivot Mode

Viewport
* Cameras
* Plane
* Volume

Compositor
* View Switch Node
* Image Node Multi-View OpenEXR support

Sequencer
* Image/Movie Strips 'Use Multiview'

UV/Image Editor
* Option to see Multi-View images in Stereo-3D or its individual images
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images

I/O
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images

Scene Render Views
* Ability to have an arbitrary number of views in the scene

Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.

Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.

Everything else is likely small todos, and may wait until we are sure none of the above is happening.

Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

* Brecht Van Lommel for the original review of the code and design early on

f3b45eb76f Fix T43987 ambient occlusion wrong for Intel cards on windows (tested on
HD3000 and HD4000 cards so far).

Similar issue to Radeon 3xxx series but Intels need the opposite factors
for dfdy.
2015-03-31 17:37:17 +02:00
590efaacb8 Potential fix for T43987, ambient occlusion different between offscreen
and on screen rendering.

Aaaaah, the beauty of driver implementations of OpenGL!

Turns out the problem here is that drivers calculate df/dy differently
in some cases (probably because OpenGL counts y reverse to how the
window system does, so drivers can get confused).

Fixed this for the ATI case based on info we have so far, there's also
the Intel case which will be handled separately (missing info on Intel's
renderer string etc).

Unfortunately we can't really fix this for the general case so we'll
have to haldle cases as they come in our tracker and by adding silly
string comparisons in our GPU initialization module <sigh>.

Quite a few things wrong here:

* Mac did not support EXT_draw_instanced, only ARB_draw_instanced
* Draw instanced did not work unless data came from vertex buffer, which
is second time we see weird things with vertex arrays in mac
* There were a few stupid mistakes by me as well, such as binding to
uniform locations for the wrong shaders (it's a wonder it ever worked

3e9947c4d4 Depth of field high quality:
A new checkbox "High quality" is provided in camera settings to enable
this. This creates a depth of field that is much closer to the rendered
result and even supports aperture blades in the effect, but it's more
expensive too. There are optimizations to do here since the technique is
very fill rate heavy.

People, be careful, this -can- lock up your screen if depth of field
blurring is too extreme.

Technical details:

This uses geometry shaders + instancing and is an adaptation of
techniques gathered from

 http://advances.realtimerendering.com/s2011/SousaSchulzKazyan%20-

* Support dithering to minimize banding.
* Optimize fill rate in geometry shader.
