- added saving of the image previews to the .blend file to prevent having to load the full images for the image previews - new struct PreviewImage in DNA_image_types can in the future be moved to struct ID for storing previews for all types

Biiig commit! Thanks to 2-3 weeks of cvs freeze... Render: - New; support for dual CPU render (SDL thread) Currently only works with alternating scanlines, but gives excellent performance. For both normal render as unified implemented. Note the "mutex" locks on z-transp buffer render and imbuf loads. - This has been made possible by major cleanups in render code, especially getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct OSA or using Materials or Texture data to write to. - Made normal render fully 4x32 floats too, and removed all old optimizes with chars or shorts. - Made normal render and unified render use same code for sky and halo render, giving equal (and better) results for halo render. Old render now also uses PostProcess options (brightness, mul, gamma) - Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer after render. Using PostProcess menu you will note an immediate re- display of image too (32 bits RGBA) - Added "Hue" and "Saturation" sliders to PostProcess options - Render module is still not having a "nice" API, but amount of dependencies went down a lot. Next todo: remove abusive "previewrender" code. The last main global in Render (struct Render) now can be re-used for fully controlling a render, to allow multiple "instances" of render to open. - Renderwindow now displays a smal bar on top with the stats, and keeps the stats after render too. Including "spare" page support. Not only easier visible that way, but also to remove the awkward code that was drawing stats in the Info header (extreme slow on some ATIs too) - Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping defines. - I might have forgotten stuff... and will write a nice doc on the architecture!

Giant commit! 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!

3D view orbit option: Around Active This fixes the active object in place when orbiting the view. Choppy 15fps demo can be seen there: http://www.elysiun.com/~theeth/bf/around_active.html Image Memory Grabage Collection This adds memory handling to the image code. An image is tagged each time it is used. During a collection cycle (frequency of cycles is user defined), if an image is older than a user defined limit, its buffer gets deallocated. This also applies to gl memory buffers. Images that are loading in GL memory needs to go through two time outs before being fully deallocated: the first time out deallocated the gl memorry, the second the buffer in ram. Notes: Image buffer loaded from python gets tagged as permanent upon load. That tag is removed when python stops using the image. I might have missed some tagging spots, especially in the rendering pipeline. Someone with more knowledge about this code should check to be careful. Tagging is done on every access, for rendering, this will probably be a performance hit. A scheme should be developped to only tag when the rendering is completed. Collecting is called in draw_object, most likely not the best place to do it. Safe from undo, since using undo deallocates memory anyway (like when loading a blend file with one currently opened) Userpref DNA changes: I've changed a couple of flagging variables from short to int. Some because they needed more space, others to keep SDNA happy. Info window changes: I've grouped a couple of buttons in aligned blocks and changed the color of mutually exclusive options to make them clearer. Matt didn't do any changes on that in tuhopuu, so hopefully I'm not stepping on anyone's feet with this. Also changed double constants into floats with f in a couple of places (mostly space.c) to make compiler happier.

Fix for reported (thanks Jens Ole!) error in rendering UV map textures. Caused by making threadsafe envmap render... Commit in convertblenderscene.c is just replacing constant with define.

void tag_image_time(struct Image *ima);
void free_old_images(void);
Couple of features/fixes: - Compositor now frees memory of buffers internally used in groups immediately. This wasn't part of the event-based cache anyway - New option: "Free Texture Images" (in render Output panel). This frees after each render of each scene all images and mipmaps as used by textures. As reference it prints total amount of MB freed. - Render stage 'creating speed vectors' had no ESC checking yet - Made drawing scanline updates during render draw 1 scanline less... dunno, still hunting for weird opengl crashes. - 3D preview render didn't properly skip sequence or composit render.
