Now one no longer needs to match the sensor dimensions with the render dimensions manually.
IMPORTANT NOTE: if you were using AUTO before with mismathing sensor aspect ratio (comparing to the render dimensions)
this will change your render! We can doversion this, but apart from Tube project I don't know if anyone else
is using this yet (part due to this bug and the only recently fixed 3dview preview aspect ratio).
That should help more artists to take advantage of this fantastic Blender feature.
It still helps to know the parameters of kwnown cameras/lens though.
For example:
Nikon DX2S with a 10.5mm fisheye can be set with:
Render resolution: 4288 x 2848
Sensor 23.7 x 15.70 (15.70 can be ommitted if AUTO is used as fit method)
Note: some cameras render different sizes according to the recording mode.
For example, a Red Scarlet in 5k (@12 fps) can render a full circular fisheye with a sigma 4.5 lens.
The same camera in the 30fps recording mode renders 4k in a cropped circular image.
So it's not only the resolution that changes, but the actual sensor been used.
So just keep in mind that the more information you have from the camera/lens you want to emulate the better.
Bug found at/patch written as a follow up of the BlenderPRO2012, patch reviewed by Brecht Van Lommel
compute_device_list is using static vector of device information which
had pointers (identifier and name) to values from device information
structures. That structures are also stored in static vector and being
refreshed every 5 seconds.
The issue is, as soon as device information is being updated, pointers
in vector from compute_device_list became incorrect.
Seems it was the reason of issues with sudden switching from CUDA to
OpenCL on my desktop and from CUDA to CPU on my laptop, It was also
seems to be making persistent images behaves instable.
Made it so device identifier and name are copied from device info
to structures used by RNA (CCLDeviceInfo).
Alternative could be avoid cacheing CCLDeviceInfo and always use actual
list of device information by RNA. It shouldn't be so much slow.
was added for cycles.
This fixes the case where the option is disabled. I moved the option now to
Blender itself and made it keep the engine around only when it's enabled. Also
fixes case where there could be issues when switching to another renderer.
r = lens * theta
Thanks for Adriano Oliveira for reporting this and chasing down the right formula.
Now fulldome works no longer need to use equisolid + a specific lens+sensor size.
And happy birthday to me. And yes, that's how I celebrate it ;)
This option enables keeping loaded images in the memory in-between
of rendering.
Implemented by keeping render engine alive for until Render structure
is being freed.
Cycles will free all data when render finishes, optionally keeping
image manager untouched. All shaders, meshes, objects will be
re-allocated next time rendering happens.
Cycles cession and scene will be re-created from scratch if render/
scene parameters were changed.
This will also allow to keep compiled OSL shaders in memory without
need to re-compile them again.
P.S. Performance panel could be cleaned up a bit, not so much happy
with it's vertical alignment currently but not sure how to make
it look better.
P.P.S. Currently the only way to free images from the device is to
disable Persistent Images option and start rendering.
There were a bunch of other issues with dupli motion blur and syncing, the problem
being that there was no proper way to detect corresponding duplis between frames
or updates. As a solution, a persistent_id was added to the DupliObject. It's an
extension of the previous index value, with one index for each dupli level. This
can be used to reliably find matching dupli objects between frames. Works with
nested duplis, multiple particle systems, etc.
for now subtype is not defined, but once we start parsing the metadata we can set texture inputs as FILEPATH
also, it takes relative strings and convert to absolute for all strings (which is arguably a good solution, but
should work for now)
Now tile size is setting up explicitly instead of using number of tiles.
This allows better control over GPU performance, where having tiles aligned
to specific size makes lots of sense.
Still to come: need to update startup.blend to make tiles size 64x64.
This commit adds memory usage information while rendering.
It reports memory used by device, meaning:
- For CPU it'll report real memory consumption
- For GPU rendering it'll report GPU memory consumption, but it'll
also mean the same memory is used from host side.
This information displays information about memory requested by Cycles,
not memory really allocated on a device. Real memory usage might be
higher because of memory fragmentation or optimistic memory allocator.
There's really nothing we can do against this.
Also in contrast with blender internal's render cycles memory usage
does not include memory used by scene, only memory needed by cycles
itself will be displayed. So don't freak out if memory usage reported
by cycles would be much lower than blender internal's.
This commit also adds RenderEngine.update_memory_stats callback which
is used to tell memory consumption from external engine to blender.
This information is used to generate information line after rendering
is finished.
"interface" appeared to be a shadowed var (or even a macro/define elsewhere)
which was causing errors like:
intern\cycles\blender\blender_mesh.cpp:124:23: error: multiple types in one
declaration
intern\cycles\blender\blender_mesh.cpp:124:23: error: declaration does not

These changes require an OSL build from this repository:
https://github.com/DingTo/OpenShadingLanguage
The lib/ OSL has not been updated yet, so you might want to keep OSL disabled
until that is done.
Still todo:
* Auto update for external .osl files not working currently, press update manually
* Node could indicate better when a refresh is needed
* Attributes like UV or generated coordinates may be missing when requested from
an OSL shader, need a way to request them to be loaded by cycles
* Expose string, enum and other non-socket parameters
* Scons build support
Thanks to Thomas, Lukas and Dalai for the implementation.
* Moved kernel/osl/nodes to kernel/shaders
* Renamed standard attributes to use geom:, particle:, object: prefixes
* Update stdosl.h to properly reflect the closures we support
* Fix the wrong stdosl.h being used for building shaders
* Add geom:numpolyvertices, geom:trianglevertices, geom:polyvertices attributes
Patch by Yasuhiro Fujii, thanks!
Original issue was that in vases viewport's lens are different from default
value switching between perspective and orthographic projections will change
viewplane a lot, which is disorienting and annoying.
Added support of such features, as:
- Ability to call RNA functions using C++ classes
For example RenderEngine.tag_update
- Property setters (for scalars and arrays)
Used Qt/jQuery-like getters/setters style, meaning Class.prop() is a getter,
Class.prop(value) is a setter.
Still to come:
Collection functions are not currently registering inside a property
Meaning BlendData.meshes wouldn't be a subclass of BlendDataMeshes result
you'll need to explicitly create BlendDataMeshes for now instead of doing
BlendData.meshes.remove()
The emitter visibility option is messy design, it makes such checks unnecessarily complicated. A better approach would be to allow non-mesh objects to carry particle data, these objects would just be invisible anyway without having to care about extra settings. However, this conflicts with the simplistic particle design of "owner is the emitter" ...
This makes it possible to do a border render inside a viewport even
when not looking through the camera.
Render border could be defined by Ctrl-B shortcut (works for both
camera render border and viewport render border).
Camera render border could still be defined using Shift-B (so no
muscule memory would be broken). Currently used a special flag of
operator to do this, otherwise you'll need to either two operators
with different poll callback or it could go into conflict with a
border zoom,
Border render of a viewport could be enabled/disabled in View
panel using "Render Border" option.
