without hurting quick texture painting
- ED_view3d_draw_offscreen will now output buffer with
transparent alpha, if sky needed it should be alpha-undered
later.
- ED_view3d_draw_offscreen_imbuf now accepts alpha mode as an
argument which could be either R_ADDSKY or R_PREMULALPHA
- OpenGL render and sequencer's opengl preview will now reflect
scene's Alpha Mode
- Quick Edit will use OpenGL with transparent alpha mode

so color management could use the same routines.
Should be no functional changes.

Clamp source coordinates to boundaries so it'll be kind of correct weight
calculated for the pixel.

tile cache code in imbuf, but it is not hooked up to the render engine.
Imbuf module: some small refactoring and removing a lot of unused or old code
(about 6.5k lines).
* Added a ImFileType struct with callbacks to make adding an file format type,
or making changes to the API easier.
* Move imbuf init/exit code into IMB_init()/IMB_exit() functions.
* Increased mipmap levels from 10 to 20, you run into this limit already with
a 2k image.
* Removed hamx, amiga, anim5 format support.
* Removed colormap saving, only simple colormap code now for reading tga.
* Removed gen_dynlibtiff.py, editing this is almost as much work as just
editing the code directly.
* Functions removed that were only used for sequencer plugin API:
IMB_anim_nextpic, IMB_clever_double, IMB_antialias, IMB_gamwarp,
IMB_scalefieldImBuf, IMB_scalefastfieldImBuf, IMB_onethird, IMB_halflace,
IMB_dit0, IMB_dit2, IMB_cspace
* Write metadata info into OpenEXR images. Can be viewed with the command
line utility 'exrheader'

lines at the seams because interpolation didnt wrap across the image.
Added bilinear_interpolation_color_wrap to be used instead of bilinear_interpolation_color for painting.
|
|
not fixed but the problem is now less bad when projection painting, bilinear interpolation was rounding down.
- added gameOb.attrDict to get the internal gameObject dict.
- mesh.getVertex wasnt setting an exception.
|
|
also changed 3 if's into a switch statement for selecting the interpolation.
|

void bicubic_interpolation(struct ImBuf *in, struct ImBuf *out, float u, float v, int xout, int yout);
void neareast_interpolation(struct ImBuf *in, struct ImBuf *out, float u, float v, int xout, int yout);
void bilinear_interpolation(struct ImBuf *in, struct ImBuf *out, float u, float v, int xout, int yout);
Added...
void bicubic_interpolation_color(struct ImBuf *in, unsigned char *col, float *col_float, float u, float v);
void neareast_interpolation_color(struct ImBuf *in, unsigned char *col, float *col_float, float u, float v);
void bilinear_interpolation_color(struct ImBuf *in, unsigned char *col, float *col_float, float u, float v);
This is needed so for projection painting but generally useful if you want to get the interpolated color of a pixel in an image without having a destination imbuf.
While editing these I noticed the functons are a bit dodgy, they assume the input ImBuf has matching float/chr buffer to the output.

instead,
Tested overall speedup is about 5x when scaling 4096x4096 -> 4000x4000 in the sequencer.
There were some artifacts in the resulting image but double checked and the old code gives the same problems.
Added back old code with #if 0's since its a bit more readable.

to - (was calling 32 pow()'s per pixel, now only 8 - approx 3-4x speedup on my system).

blocks that were previously missed; and b) greatly increase my
ohloh stats!

This fixes:
[#7989] Sequence editor preview and anim render output broken on Linux PPC
and also optimizes RGBA -> ABGR conversion function a little bit.
(Fixing also a crash, if there is no ibuf->rect available...)
|
|
uninitialised vars.
|
|
Bugfix for transform effect by Damiles.
Fixes crash with float buffers. (Don't try to render into output buffers,
that do not exist...)
|
|
I left the link that points to documentation on the web so not really needed
anyway.

Its a subset of patch [#6766] Transform Sequencer effect
It adds 3 image functions for different types of interpolation.

Credits go to Gernot Ziegler, who originally coded EXR support, and to
Austin Benesh for bringing it further. Kent Mein provided a lot of code
for integrating float buffers in Blender imbuf and ImBuf API cleanup,
and provided Make and Scons and static linking.
At this moment; the EXR libraries are a *dependency*, so you cannot get
the Orange branch compiled without having OpenEXR installed. Get the
(precompiled or sources) stuff from www.openexr.com. Current default is
that the headers and lib resides in /user/local/
Several changes/additions/fixes were added:
- EXR code only supported 'half' format (16 bits per channel). I've added
float writing, but for reading it I need tomorrow. :)
- Quite some clumsy copying of data happened in EXR code.
- cleaned up the api calls already a bit, preparing for more advanced
support
- Zbuffers were saved 16 bits, now 32 bits
- automatic adding of .exr extensions went wrong
Imbuf:
- added proper imbuf->flags and imbuf->mall support for float buffers, it
was created for *each* imbuf. :)
- found bugs for float buffers in scaling and flipping. Code there will
need more checks still
- imbuf also needs to be verified to behave properly when no 32 bits
rect exists (for saving for example)
TODO:
- support internal float images for textures, backbuf, AO probes, and
display in Image window
Hope this commit won't screwup syncing with bf-blender... :/

I just fixed indentation (replaced spaces with tabs where needed) and removed
#include config.h stuff from the above files.
Kent
|

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
Just need to finish cpp files now :)
