data to renderdata. However, if a camera has a lens-ipo, this has to be
calculated correctly each time.
Actually, render system suffers like Blender itself from a weak time
system... which still is polluted by confusing globals. Should all work
now, but definitely needs attention later.
Image Node now supports animations as well. Press the 'Sequence' Icon in
the node to see the options:
- Frs: the amount of images involved in the sequence
- SFra: start frame, the Blender frame number
- First: the number in the name of the first image in the sequence
- Cycl: make the sequence go cyclic
The images are refreshed on each call to execute the node tree, but not
on advancing frames in Blender... I suspect that might make it to slow now,
will first have to code nice threaded/optimized updates in compositor.
Access to G.vd without an active 3D window from sequences during Alt-A
playback caused segfault; check and return if it's NULL, and print an error
to stderr. (Someone should check why viewmove() is being called).
The further you drag the bigger the number gets (like gimp/photoshop brush size slider)
Works for ranges: float buttons bigger then 11 and int buttons bigger then 129.
- New Node "Composite" is output node that puts composited result back
in render pipeline.
- This then also displays in the render window while editing
- But, only with Scene buttons option "Do Compositor" set
- Then, just press F12 or render anims to see the magic!
For clarity, the former 'Output" node is renamed to "Viewer".
- Curves in Image window didn't copy alpha (when no 32 bits rect for
display was made already).
- Code was missing to validate grouped nodes in Compositor, didnt work
at all yet
- Loading new Images in a Node (using filewindow) didn't assign the image
Image window now displays Alpha for float images too
- Image curves are only applied now when curves panel is in use. Closing
the panel will disable curves, reopen Panel enable curves.
You can minimize the Curves panel to keep it active. That latter then
works as visualization curves are being applied.
- Compositor output now also uses Image window curves, if active.
A full detailed description of this will be done later... is several days
of work. Here's a summary:
Render:
- Full cleanup of render code, removing *all* globals and bad level calls
all over blender. Render module is now not called abusive anymore
- API-fied calls to rendering
- Full recode of internal render pipeline. Is now rendering tiles by
default, prepared for much smarter 'bucket' render later.
- Each thread now can render a full part
- Renders were tested with 4 threads, goes fine, apart from some lookup
tables in softshadow and AO still
- Rendering is prepared to do multiple layers and passes
- No single 32 bits trick in render code anymore, all 100% floats now.
Writing images/movies
- moved writing images to blender kernel (bye bye 'schrijfplaatje'!)
- made a new Movie handle system, also in kernel. This will enable much
easier use of movies in Blender
PreviewRender:
- Using new render API, previewrender (in buttons) now uses regular render
code to generate images.
- new datafile 'preview.blend.c' has the preview scenes in it
- previews get rendered in exact displayed size (1 pixel = 1 pixel)
3D Preview render
- new; press Pkey in 3d window, for a panel that continuously renders
(pkey is for games, i know... but we dont do that in orange now!)
- this render works nearly identical to buttons-preview render, so it stops
rendering on any event (mouse, keyboard, etc)
- on moving/scaling the panel, the render code doesn't recreate all geometry
- same for shifting/panning view
- all other operations (now) regenerate the full render database still.
- this is WIP... but big fun, especially for simple scenes!
Compositor
- Using same node system as now in use for shaders, you can composit images
- works pretty straightforward... needs much more options/tools and integration
with rendering still
- is not threaded yet, nor is so smart to only recalculate changes... will be
done soon!
- the "Render Result" node will get all layers/passes as output sockets
- The "Output" node renders to a builtin image, which you can view in the Image
window. (yes, output nodes to render-result, and to files, is on the list!)
The Bad News
- "Unified Render" is removed. It might come back in some stage, but this
system should be built from scratch. I can't really understand this code...
I expect it is not much needed, especially with advanced layer/passes
control
- Panorama render, Field render, Motion blur, is not coded yet... (I had to
recode every single feature in render, so...!)
- Lens Flare is also not back... needs total revision, might become composit
effect though (using zbuffer for visibility)
- Part render is gone! (well, thats obvious, its default now).
- The render window is only restored with limited functionality... I am going
to check first the option to render to a Image window, so Blender can become
a true single-window application. :)
For example, the 'Spare render buffer' (jkey) doesnt work.
- Render with border, now default creates a smaller image
- No zbuffers are written yet... on the todo!
- Scons files and MSVC will need work to get compiling again
OK... thats what I can quickly recall. Now go compiling!
reduction that was labeled "Percent" but was on a scale from
0.0 to 1.0. The word percent implies a scale for 0 to 100, so
I've relabeled this slider as "Ratio".
Bugfix #3660: NMesh.getVertexInfluences() was broken following the changes
to the armature system. Tron Thomas (kudos) came up with a fix that seems
to perform identically to the old method. I'm also adding it to the Mesh
module for compatibility.
View All/View Selected - only took into account values from 1 axis. - Workaround because test_view2d needs to act that way for other functions.
Easy one :) Right mouse mutton cancels transform. - Must move to Theeth's new code one day.
Patch #3760: Allows a python script to call renderer when the UI is not
active (thanks to Cory King for patch). Without the patch, blender will
segfault since G.vd is NULL.
* Scaled down image can be smaller than icon - bad memory access
* Also needed to copy float buffer for exr images
* rectcpy only copied first row
There probably is some unnessary copying, will check with a little more time.
For now better be safe since it's no huge amount of mem that is copied.
patch from jean-michel soler (jms) - .insertShapeKey()
Python API, a function to insert a shape key in an object . It works on Mesh, Lattice curve ans surface .
Example of use :
import Blender
OBJECT=Blender.Object.GetSelected()[0]
OBJECT.insertShapeKey()
a docstring to follow soon
Added Mesh.Modes() function, which allows scripts to get/set the selection
mode settings for meshes. This was necessary in order for the mesh tools
such as triangulate, remove doubles, etc., to work properly.
to get the current value of the IPO shape key. There are still some issues
to discuss as to whether methods/attributes should be used and what they
should be named, but this will (or should) be addressed in the upcoming API
rewrite.
(with make, need to confirm with scons)
after cleaning the changes are in fact minimal, but the situation
is still quite a bit hackish.
Game engine coders, there is also quite a number of warnings that
need to be fixed.
current situation is that everything seems to work, but GLSL shaders
spew a lot of errors on console and blender may crash on exit when
a GLSL shader was used. ARB stuff works fine.
