The expression module now uses an EXP prefix and it follows a
distribution similar to blender.
Additionally the hash function in EXP_HashedPtr.h was simplified and the
files EXP_C-Api.h &.EXP_C-Api.cpp were deleted because were unused.

This is essential for video projection, and the alternative until now was to manually change the projection matrix via Python.
( http://www.blender.org/manual/game_engine/camera/introduction.html#camera-lens-shift
- this page will be removed as soon as I commit this)
Also this is working for perspective and orto cameras BUT if the sensor is not AUTO it will only look correct in blenderplayer (this is an unrelated bug, but just in case someone runs into it while testing this, now you know why you got the issue).
Kudos for the BlenderVR project for supporting this feature development.

Now we use color converted (if we do a color management) by the setter for background color in VideoTexture (ImageRender & ImageMirror).

Now internally the variables are processed as floats avoiding int->float->char conversions that are causing precision lost.
A check for int numbers is maintained to keep compatibility with old behaviour.

rendering
Make scene background color as default for render-to-texture instead of
current blue color (0, 0, 255).
It is very useful for mirrors setups.

In quad-buffer stereo mode, the GE render pass ends with the right eye on the right buffer, but we need to draw on the left buffer to capture the render.

This is mostly the same fix as before, but now code depending on culling
checks is executed after KX_Scene->CalculateVisibleMeshes(). As a
side-effect, LoD checks and animation culling now use the current
frame's culling information rather than the previous frame's.
This fix is mostly based off of HG1's patch from the bug report, which had ImageRender::Render() call KX_KetsjiEngine::RenderFonts(). However, I have moved RenderFonts() from KX_KetsjiEngine to KX_Scene where all of the other font and rendering functions are. The real fix for this mess would be to not have ImageRender::Render() have so much duplicate code from KX_KetsjiEngine::Render(), but that's a code cleanup problem for another day.
- PyLong_FromSsize_t --> PyLong_FromLong
- PyLong_AsSsize_t --> PyLong_AsLong
In all places except for those where python api expects PySsize_t (index lookups mainly).
- use PyBool_FromLong in a few areas of the BGE.
- fix incorrect assumption in the BGE that PySequence_Check() means PySequence_Fast_ functions can be used.
2 new attributes to ImageViewport and ImageRender object:
depth: set to True to retrieve the depth buffer as an array of float
(not suitable for texture source).
zbuff: set to True to retrieve the depth buffer as a grey scale pixel array
(suitable for texture source).
A new mode 'F' is added to VideoTexture.imageToArray() to allow returning the image
buffer as a one dimensional array of float. This mode should only be used to retrieve
the depth buffer of ImageViewport and ImageRender objects.
Example:
viewport = VideoTexture.ImageViewport()
viewport.depth = True
depth = VideoTexture.imageToArray(viewport,'F')
# show depth of bottom left pixel
# 1.0 = infinite, 0.0 = on near clip plane.
print(depth[0])
- Added support of variable size sensor width and height.
- Added presets for most common cameras, also new presets can be defined by user.
- Added option to control which dimension (vertical or horizontal) of sensor
size defines FOV. Old behavior of automatic FOV calculation is also kept.
- Renderer, viewport, game engine and collada importer/exporter should
deal fine with this changes. Other exporters would be updated soon.
- Use BGL buffer instead of string for image data.
- Add buffer interface to image source.
- Allow customization of pixel format.
- Add valid property to check if the image data is available.
The image property of all Image source objects will now
return a BGL 'buffer' object. Previously it was returning
a string, which was not working at all with Python 3.1.
The BGL buffer type allows sequence access to bytes and
is directly usable in BGL OpenGL wrapper functions.
The buffer is formated as a 1 dimensional array of bytes
with 4 bytes per pixel in RGBA order.
BGL buffers will also be accepted in the ImageBuff load()
and plot() functions.
It is possible to customize the pixel format by using
the VideoTexture.imageToArray(image, mode) function:
the first argument is a Image source object, the second
optional argument is a format string using the R, G, B,
A, 0 and 1 characters. For example "BGR" means that each
pixel will be 3 bytes, corresponding to the Blue, Green
and Red channel in that order. Use 0 for a fixed hex 00
value, 1 for hex FF. The default mode is "RGBA".
All Image source objects now support the buffer interface
which allows to create memoryview objects for direct access
to the image internal buffer without memory copy. The buffer
format is one dimensional array of bytes with 4 bytes per
pixel in RGBA order. The buffer is writable, which allows
custom modifications of the image data.
v = memoryview(source)
A bug in the Python 3.1 buffer API will cause a crash if
the memoryview object cannot be created. Therefore, you
must always check first that an image data is available
before creating a memoryview object. Use the new valid
attribute for that:
if source.valid:
v = memoryview(source)
...
Note: the BGL buffer object itself does not yet support
the buffer interface.
Note: the valid attribute makes sense only if you use
image source in conjunction with texture object like this:
# refresh texture but keep image data in memory
texture.refresh(False)
if texture.source.valid:
v = memoryview(texture.source)
# process image
...
# invalidate image for next texture refresh
texture.source.refresh()
Limitation: While memoryview objects exist, the image cannot be
resized. Resizing occurs with ImageViewport objects when the
viewport size is changed or with ImageFFmpeg when a new image
is reloaded for example. Any attempt to resize will cause a
runtime error. Delete the memoryview objects is you want to
resize an image source object.
Add optional parameter to VideoTexture.Texture refresh() method
to specify timestamp (in seconds from start of movie) of the frame
to be loaded. This value is passed down to image source and for
VideoFFmpeg source, it is used instead of current time to load
the frame from the video file.
When combined with an audio actuator, it can be used to synchronize
the sound and the image: specify the same video file in the sound
actuator and use the KX_SoundActuator time attribute as timestamp
to refresh: the frame corresponding to the sound will be loaded:
GameLogic.video.refresh(True, soundAct.time)
