- pending commit for OSX intel systems, with intel graphics. These now call
an extra swapbuffers after glFlush(). Code is ifdeffed, and doesnt affect
other systems.
- show-off commit: option to have transparent nodes over the composite
result. Only draws Image for active Viewer Node now, and image doesnt
translate nor zoom (which isnt bad though).
Set in themes the alpha color of "node backdrop" to make nodes
transparent.
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!
When using 3d window "unlocked" (own layer and own camera possible), the
dependency updates didn't work, these were only using Scene layers.
Changed the dependency graph call DAG_scene_flush_update()
to accept an argument for all visible layers in a Screen.
- *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
Using the Play button in timeline, now uses an event-driven system to
update the animation system and signal windows to redraw. Meaning the
full UI remains responsive!
Check the new Pulldown "Playback" to set which windows you like to see
updated. Same settings is used for LMB 'dragging' frames in Timeline.
Implementation notes;
- the Icon for 'Pause' (or stop) has to be made yet, I commit this from
my laptop... all was coded during a 2 x 5 hour train ride to germany
- the anim playback system (ALT+A too) now uses correct "frames per
second" as maximum speed. Buttons can be found in 3 places in the UI,
also added it as pulldown item
- The system works with 'screen handlers', which has been coded with
using Python (networked) events or verse in mind too. A doc on that
will follow.
- the buttons code has been made 'resistant' to animated UIs too,
preventing flashing of hilites.
- All subloops (like transform) stop playback, with exception of MMB
view manipulations.
As extra; found tweak to make Textured AA fonts draw without distortion.
Looks perfect here on laptop now (like Pixmap fonts) and is 20x faster.
On large changes of the Lattice resolution button, the undopush crashed.
Reason was that the push happened for buttons before the actual event for
buttons was executed.
Solved by creating new event UNDOPUSH that's being added to the queue by
by buttons now.
- Made button undo texts for number buttons more clear
- Added undo push for missing Add lamp/empty/lattice/camera
Made extrude along normals more sane. Now behave like a move along an arbitrary axis (including Ctrl/Shift applications and typemode). Also prints "Along faces normal" in the header, to tell the user what's happening.
----- Killed UI frontbuffer draw
The interface toolkit was drawing all live updates (while using menus/buttons)
in the frontbuffer. This isn't well supported cross-platform, so time to be
killed once. Now it uses *only* glReadPixels and glCopyPixels for frontbuffer
access.
Live updates or menus now are drawn in backbuffer always, and copied to
front when needed.
NOTE: it was tested, but needs thorough review! On PC systems I suspects
backbuffer selection to screw up (check!). On SGI/SUN workstations it
should work smooth; but I need evidence
----- Smaller fixes;
- AA fonts were garbled on ATI systems. Now the AA fonts are drawn exact
on pixel positions. Needs the new FTGL libb too, patch is on maillist
- Rounded theme uses antialiased outlines
- Pulldown and popup menus have nice softshadow now
- New button type 'PULLDOWN', thats the one that callsup a pulldown menu.
Should be added to themes, as is the full menu/pulldown drawing
- Screendump for 1 window does the full window now, including header
- Empty pulldowns (for example running blender without scripts) give no
drawing error anymore
For review & fun;
- added curved lines as connectors, for Oops window
- small additions and fixes to enable the demo mode;
- Added sleep() to Blender.sys and 17 new functions to Blender.Window module:
things to help demo script writing and as a bonus read / write access to Blender's input event queue;
- updates in docs, those interested please check Window.py in python/api2_2x/doc/ to read about the new Blender.Window functions.
----
Demo mode should be working well now for (I) playing rt animation -- aka ALT+A -- and (II) rendering pics and anims and playing anims. I'll still add access to radiosity data and functions.
PS: Joseph Gilbert made (II) possible with the Scene.Render module he added for 2.32. He's been coding great things for bpython, so I'd like to take the chance to point that and thank him here.
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)
(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
