from 0 - 1, instead of -1 to 1. Thats fixed.
The error made tests i did with alpha make nice though, apparently hairs
are nicer when rendered with alpha range 0.0 to 0.5.
memory. Poses should be relinked right after duplicating, not during a
redraw (when more objects use same armature).
Added in readfile a patch to make sure files saved with this duplicate
error can still be used.
temporary fix (duplicating code again), the *real* fix would be to once
make one central function to create and init a text object for all
places...
I also tried to introduce compatibility code to be able to load old files
with broken text objects (cu->tb == NULL due to missing init code).
Hope it works :)
This means the diffuse and specular shaders don't use the normal
for hair (which is actually undefined, a hair is micro cylinder) but
it uses the tangent vector (vector in direction of hair).
For Diffuse, it computes a fake normal now, representing the optimal
hair normal pointing towards the light. All current builtin shaders
work with this, including ramps.
For Specular, it uses another formula to remap dot products for all
lines that now use the tangent vector instead of the normal:
dot = vector * tangent
dot = sqrt(1.0 - dot*dot)
Gives better results than using the 'fake' normal for diffuse. Officially
(according the papers) this could be used for diffuse too, but then hair
becomes very flat. Now you can control the flatness easily with ramps or
using Oren-Nayer for example.

- Added new texture channel "Strand" to apply textures on hairs over the
length of hair (1 dimensional). Orco now gives 1 fixed coordinate for
the entire hair, based on where it starts.
Note; UV doesn't work yet. Nor vertexcolor.

- debug output now controlled globally by elbeem debug level
(BLENDER_ELBEEMDEBUG environment var), also for fluidsimBake
and read/writeBobj
- debug output is written to file for WIN32
- added "for" and "vector" etc. defines for MSVC6
(I couldnt get hold of the compiler itself, so not tested yet)
- buttons "Show" and "Key" didn't set the active constraint, causing
confusement in display for the IpoWindow
Also made the backdrop for constraints and modifiers to use the Panel
theme color, making it better integrated.
unpredictable one!
This is what it did; if two or more Constraints are of the same type, it
accumulates the Target positions/rotations for the constraints, averages
them, and then only applies the last Constraint in the row. It seems to
be a trick to blend IK Constraints or so... in all other cases I cannot
find a good use for it (nor did Bassam).
For example; add three Empties, and make one Empty to have 2 location
constraints to the other two. This just didn't work, unless you insert
an "Empty" constraint inbetween.
I will post in the blender.org animation forum feedback for it too. :)
Its quite easy to make it an option, but I first like to grasp fully what
the actual use of such an option is.
for some configs. This was an old hack for sgi's, so I've put it behind an
ifdef for sgi and suns now.
Test if blender still works by switching screens, and check for the borders
between the blender area windows. These should draw all nice empty/black.
directory... so the slowdown was still evident!
Maintenance commit;
- *Giant* speedup for LMB frame-dragging in ipo/action/nla windows. It was
calling a routine that accessed frontbuffer drawing.... a very old patch
for SGIs even! :)
- Prepared code for support of unlimited Shape keys
- Curve objects didnt draw correct for selection-outline option
Thanks to testing in studio orange (thnx andy, matt!) I've found the
simple way to code it.
Static particle systems, when not set to wire or halo, now render 1 pixel
wide 'strands', which are actually just faces with vertexnormals and
proper orco texture. Check for quick fun;

(and rt6, rt7, rt8)
- should allow users to render a filename.extension to the render path
Example:
import Blender
s = Blender.Scene.GetCurrent()
r = s.getRenderingContext()
r.setRenderPath('C:\\')
r.render()
r.saveRenderedImage('myRender.jpg')
Blender.Scene.Render.CloseRenderWindow()

- Prepared code for support of unlimited Shape keys
- Curve objects didnt draw correct for selection-outline option
- adding new Shape didn't set correct Ipocurve code... so you could not
even add new curves
- the keylines (first channel) always came back in display... ancient error
User doc: http://www.blender3d.org/cms/Shape_Keys.678.0.html
- The mixed use of "Vertex Key","Key" or "RVK" in Blender was a bit
confusing. Also a 'vertex key' assumes keys per vertex, which actually is
only a single key for the entire shape. The discussions on blender.org
forums all mentioned "Shape" or "Blend Shapes", which I think is an OK
name for a "Vertex Key" in the UI. :)
- Most work was code spaghetti cleanup. Doing shape-keys now nicely goes
via the depgraph and DerivedMesh. That then allows to have different
shapes per object, with the new "Pin" feature.
Objects now define what Shape is shown (ob->shapenr)
- Added a Shape Panel in the Edit buttons with the various options
- Fixed a lot of issues in the IpoWindow, with drawing the channels.
For example, deleting a key-line there caused the entire Relative option to
go wrong, same for moving the lines up/down.
Changing key-line order now reflects in order of channels. The active
Shape is drawn more clear now too.
- Noticed it doesnt work yet for curves/lattice. Need modifier advise!
caused a myriad of other errors in tools... now you couldn't create a
triangle if one 1 edge was in a face already.
I should have known it should be coded differently. :)
So, here's another version, which actually restores the old code, and
only has the exception on pressing Fkey.
Hooks now support vertex groups. With weight painting it looks very
interesting. Almost z-painting! :) Try a sphere with all vertices in a
group, hook it, and scale empty in object mode a bit.

(Which gives the idea to make a Displace Modifier working with normals and
vertexgroups..)
Works as follows now; in Mesh editmode, when no vertices are selected, it
tries to assign on CTRL+H command the active Vertex Group. (Menu is getting
to long now... need to think over). Only works when vertices are assigned
to a Vertex Group, this to calculate the Hook center.
- Trackball rotate was missing the NoConstraints flag
- Zooming didn't recalculate the 2D center correctly
- Zooming in transform was sending event to the 3D window even when working on UVs. (disabled when working on UVs for now, will need to send events to a 2D window handler eventually)
- In camera mode, when the selection was exactly on the camera, initgrabz was barfing, fallback to 1.0 now, which gives ok results.
Grmble... and now the feature ALT+J 'join triangles' broke. :)
Also found out the Fkey option didn't work anymore on 2 triangles (makes 1
quad too). Luckily we got people testing eh!
Hrms... previous commit here to make sure faces are not added 'double',
caused a part in removedoubles not to work well, removing too many
faces. Solved it more proper now.
