for it. Now win32 users should have less problems.
I added export of the "no shadow" flag (traceable) And changed the reflection
export scheme so now blender's RayMir is used as yafray's min_refle and the
amount of reflection is controled by the mir color. This seems more intuitive.
And now IOR is exported also for reflection only, wich is needed for fresnel.
- New lamp type added "Area". This uses the radiosity formula (Stoke) to
calculate the amount of energy which is received from a plane. Result
is very nice local light, which nicely spreads out.
- Area lamps have a 'gamma' option to control the light spread
- Area lamp builtin sizes: square, rect, cube & box. Only first 2 are
implemented. Set a type, and define area size
- Button area size won't affect the amount of energy. But scaling the lamp
in 3d window will do. This is to cover the case when you scale an entire
scene, the light then will remain identical
If you just want to change area lamp size, use buttons when you dont want
to make the scene too bright or too dark
- Since area lights realistically are sensitive for distance (quadratic), the
effect it has is quickly too much, or too less. For this the "Dist" value
in Lamp can be used. Set it at Dist=10 to have reasonable light on distance
10 Blender units (assumed you didnt scale lamp object).
- I tried square sized specularity, but this looked totally weird. Not
committed
- Plan is to extend area light with 3d dimensions, boxes and cubes.
- Note that area light is one-sided, towards negative Z. I need to design
a nice drawing method for it.
Area Shadow
- Since there are a lot of variables associated with soft shadow, they now
only are available for Area lights. Allowing spot & normal lamp to have
soft shadow is possible though, but will require a reorganisation of the
Lamp buttons. Is a point of research & feedback still.
- Apart from area size, you now can individually set amount of samples in
X and Y direction (for area lamp type 'Rect'). For box type area lamp,
this will become 3 dimensions
- Area shadows have four options:
"Clip circle" : only uses a circular shape of samples, gives smoother
results
"Dither" : use a 2x2 dither mask
"Jitter" : applys a pseudo-random offset to samples
"Umbra" : extra emphasis on area that's fully in shadow.
Raytrace speedup
- improved filling in faces in Octree. Large faces occupied too many nodes
- added a coherence check; rays fired sequentially that begin and end in
same octree nodes, and that don't intersect, are quickly rejected
- rendering shadow scenes benefits from this 20-40%. My statue test monkey
file now renders in 19 seconds (was 30).
Plus:
- adjusted specular max to 511, and made sure Blinn spec has again this
incredible small spec size
- for UI rounded theme: the color "button" displayed RGB color too dark
- fixed countall() function, to also include Subsurf totals
- removed setting the 'near' clipping for pressing dot-key numpad
- when you press the buttons-window icon for 'Shading Context' the context
automaticilly switches as with F5 hotkey
Please be warned that this is not a release... settings in files might not
work as it did, nor guaranteed to work when we do a release. :)
- add a new space: Space Script
- add a new dna struct: Script
- add these two properly everywhere they are meant to
It's not a tiny commit, but most of it is ground work for what is still to be done.
Right now the benefits should be: freeing the Text Editor to be used in a window even while a script w/ gui in "on" and letting more than one currently running script w/ gui be accessible from each window
Some files are added, so some build systems (not autotools) will need updates
this is part 1 of the UI makeover. It has:
- menu system from Matt integrated
- buttons drawing from Matt
- generic button panel system implemented
- converted displaybuttons (not the rest yet)
- cleaned up a lot in drawing spaces itself, to make it aligned and pixel exact.
- cleaned loads of little compiler warnings, protos...
still a lot of work needed, will all be in next week i hope!
(warn: 2 new c files! butspace.c and buttons_scene.c)
All modifications are behind compileflag INTERNATIONAL,
and affect these two directories; source/blender/src and
source/blender/ftfont.
Thanks to philipp, a new utf8towchar() function is added
to Shizu's work, which fixes the international support for
OSX. It also makes the iconv library obsolete. This means
all translation files (blender.mo) need to be 'recoded' to
UTF-8, and language support in the fileselect window and
the text editor is not possible. Iconv might be added in
the future to enable these features.
Redesigned the userpreference window layout. (not finished yet)
Enhanced the texteditor with; a rightmousemenu, clipboard text
support (for windows !) and the alt-m keystroke generates a 3d
text object. (up to 1000 characters)
(1, 2, 3, 4 and 7 from http://www.tncci.com/blender/feats.html)
(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac
