The 'use_panorama' option is now part of a new Camera type: 'Panorama'.
Created two other panorama cameras:
- Equisolid: most of lens in the market simulate this lens - e.g. Nikon, Canon, ...)
this works as a real lens up to an extent. The final result takes the
sensor dimensions into account also.
.:. to simulate a Nikon DX2S with a 10.5mm lens do:
sensor: 23.7 x 15.7
fisheye lens: 10.5
fisheye fov: 180
render dimensions: 4288 x 2848
- Equidistant: this is not a real lens model. Although the old equidistant lens simulate
this lens. The result is always as a circular fisheye that takes the whole sensor
(in other words, it doesn't take the sensor into consideration).
This is perfect for fulldomes ;)
For the UI we have 10 to 360 as soft values and 10 to 3600 as hard values (because we can).

Note, this is not a real simulation of the light path through the lens.
The ideal solution would be this:

Thanks Brecht for the fix, suggestions and code review.
Kudos for the dome community for keeping me stimulated on the topic since 2009 ;)
Patch partly implemented during lab time at VisGraf, IMPA - Rio de Janeiro.

Note about long lines: I did not touch to two pieces of code (because I don’t see any way to keep a nicely formated, compact code, with shorter lines):
* The node types definitions into rna_nodetree_types.h
* The vgroup name functions into rna_particle.c
|
|
Addresses:
* C++ comments.
* Spaces after if/for/while/switch statements.
* Spaces around assignment operators.
|
|
* Tweak description of sensor fit property.
* Fix sensor display for auto and vertical fit.
* Fix incorrect aspect ratio for camera frame drawing.
|
|
3d view, deduplicating the complex code for setting up the viewplane.
|
|
- 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.

vecs = Camera.view_frame(scene)
returns 4 points for the camera frame, without this its very hard to know if a point is in the camera view or not, without rewriting blenders internal logic in python.
|

* Increase "Ortho_scale" maximum from 1k to 4k, Request by francoisgfx.

strange.

removed diagonal golden rule (not very common), added harmonious triangle and golden triangle options.

- move GS() define into DNA_ID.h
- add BLI_utildefines as an automatic include with makesrna generated files.
|
|
MAKE_ID, FILE_MAXDIR, moved the generic defines to BLI_utildefines.h.
no functional changes.

where both lens and angle are animated
(2 fcurves accessing the same data), this should be handled by the units system but for now disabling this means we don't have to deal with animated angle later on.
note: durian files didnt use animated angle anywhere.

least its very unlikely).
|
|
Metric or Imperial - minor
- pick the closest unit that matches the existing step size.
- set the distance subtype on some camera flags.
- commented mesh flag 'ME_ISDONE' its nolonger used.

Removed the camera->angle from DNA, now it just uses RNA to handle the conversions.
Really need to convert this to physical units at some point... :/
|

Sincronized millimeters - angle limits
Better tooltips
Removed dots at end of tooltips in camera rna file too (as discused with
Ton and DingTo on irc)

wohooo first commit! :D

It's not range_ui, but range itself. if someone think that for some reason it's better to keep the visible range up to 100 (the current one) it could be as well.

* Property update functions no longer get context, instead they get only
Main and Scene. The RNA api was intended to be as context-less as
possible, since it doesn't really matter who is changing the property,
everything that uses the property should be updated.
* There's still one exception case that use it now, screen operations
still depend on context too much. It also revealed a few places using
context where they shouldn't.
* Ideally Scene shouldn't be passed, but much of Blender still depends on
it, should be dropped when we try to support multiple scene editing.
Change was planned for a while, but need this now to be able to call
update without a context pointer.

% sign for percentage assuming it is between 0-100, while factor is
for values 0-1.
Move collision setting absorption from modifier to collision settings,
was inconsistent to have it there as the only one, and made it have
range 0.0-1.0 instead of 0-100.

* UI layout for scene buttons has quite some changes, I tried to
better organize things according to the pipeline, and also showing
important properties by default, and collapsing less important ones.
Some changes compared to 2.4x:
* Panorama is now a Camera property.
* Sequence and Compositing are now enabled by default, but will only
do something when there is a node tree using nodes, or a strip in the
sequence editor.
* Enabling Full Sample now automatically enables Save Buffers too.
* Stamp option to include info in file is removed, it now simply always
does this if one of the stamp infos is enabled.
* Xvid, H.264 and Ogg Theora are now directly in the file format menu,
but still using FFMPEG. Unfortunately Ogg is broken at the moment
(also in 2.4x), so that's disabled. And Xvid crashes on 64bit linux,
maybe solvable by upgrading extern/xvidcore/, using ubuntu libs makes
it work.
* Organized file format menu by image/movie types.
Added:
* Render layers RNA wrapped, operatorized, layouted.
* FFMPEG format/codec options are now working.
Defaults changed:
* Compositing & Sequencer enabled.
* Tiles set to 8x8.
* Time/Date/Frame/Scene/Camera/Filename enabled for stamp.

* Added icon to property and enum property items. The latter is
responsible for the large number of files changed.
* For RNA functions, added PROP_RNAPTR flag to ask for a PointerRNA
as argument instead of a C pointer, instead of doing it implicitly
with the AnyType type.
* Material: properly wrap diffuse/specular param variables, and
rename some things for consistency.
* MaterialTextureSlot: added "enabled" property (ma->septex).
* Image: make animated property editable.
* Image Editor: make some things editable, notifiers, respect state.
* Context: fix issue with screen not being set as ID.
|
|
* Tooltip updates by William Reynish. Thanks!
|
|
* Added an icon entry to RNA structs, instead of the UI_GetIconRNA
function, to keep code together a bit more and make the lookup
faster.
|
|
|
|
* Automatically do us++ and us-- reference counting in ID pointer
set functions.
* Added an enum property callback to dynamically vary the list of
available items.
* Added some functions to do removes on pointers and collections
runtime defined for RNA and using ID properties.
* Constraints now have owner/target space wrapped, and most
pointers made editable. They can be ported to use python layouts.
* Also other pointers made editable that I think are see now with
the automatic reference counting.
|
|
* Added new Buttons Tab "Bone" for Armature objects.
* Validation of buttons selection, when object selection is changed.
* added missing notifier for camera type and small layout change to the panel.
* more shading color changes for menu and checkbox.

It's about time that the RNA wrapping for various parts of the animation system were cleaned up for my recent changes. I've moved some code around (and/or deleted a file or two) in the process.
|
|
* Finished DNA_lamp_types.h, DNA_world_types.h and DNA_sound_types.h.
* Renamed "parent" struct property to "nested", and also remaining "from"
usage to "base".
* Added a NEVER_NULL subtype for pointers and use it for all properties
that apply.
* Make sure all structs have a description, and fix any other DOC_BROKEN
descriptions, also many other naming consistency improvements.
|
|
* Some tweaks to rna property descriptions
|
|
accessible via python)
Many descriptions are not written, grep for DOC_BROKEN if you have some spare time to write struct descriptions.
|
|
* Added a function to define booleans negative, to turn negative
properties into positive ones gettin rid of the no_ prefix, and
also got rid of the use_ prefix for two booleans.
* Also made the function for enum bitflags separate, this is quite
rare so don't need to bother with this in most cases.
* Removed svn:executable flags from some files.
