* This fix is really only a bandage, as the underlying issue is that sequencer preview render doesn't yet use the job system.
* The sequencer preview can start a full render of the scene, and this can collide with other preview/actual renders in many cases.
* Drawing the sequencer preview is now disabled when an other render is in progress, but the sequence preview rendering could have already been started before the other render, so this doesn't really fix anything.
* For now only OpenGL rendering can be used for the sequencer preview reliably until it's reimplemented using the job system.
* Using the job system in the future can handle the clashes between different renders properly and will give users a nice progress bar to indicate something is happening while the preview is recalculated.
After discussions with Campbell regarding #24336 and #24309, we've decided to make this property for curves to only get set when an F-Curve explicitly animates it.
As a consequence...
- ALL OLD FILES using follow-path constraints that depended on this changed behaviour will currently need manual patching to add an appropriate F-Curve
- Ctrl-P (Parenting to Curves -> Follow Path option) will now automatically create such F-Curves mimicking the old behaviour so that creating camera-following-path setups still works smoothly.
- Directly adding a Follow Path constraint bypasses this, so you'll need to manually add such F-Curves if you need them.
The main problem with the old approach was that there were many cases in which curve data could get added but the ctime would be incorrect until a frame change (i.e. on render) flushed this.
The problem is the opensource nvidia nouveau drivers are slow running glReadPixels(), was hanging on memcpy().
However for autodepth its not needed to update the entire 3D view depths, so added view3d_update_depths_rect() to get the depths for a smaller area.
Rather then have the modifier calculate ORIGINDEX weather its needed or not (incorrect if it wasn't the first modifier on the stack),
create ORIGINDEX layer initially if any of the modifiers use it.
This way hook also works after Mirror and Screw modifiers which have the ORIGINDEX layer copied implicitly with DM_copy_vert_data().
This wasn't possible to check for before because this flag was always enabled so it would be passed to DM_set_only_copy().
Now just add the flag whenever calling DM_set_only_copy().
committed r32598 to fix [#24309] Reloading file with incorrect path location.
Setting the curves ctime when updating the object data overrode the animated value.
For now just set the ctime on newly added curves with will work as the user expects in most cases.
This is weak design IMHO because the ctime value can be set to anything but is reset on changing frames even if its not keyed.
With curves created via python or linked in this can still result in a bad ctime value.
also added api function ED_area_tag_redraw_regiontype(), so an area can redraw all regions by type.
In this case there is a view3d area listener that needs to draw all WINDOW regions.
Fixed bug #22634, sculpting/multires and wireframe display mode glitches
* Changed ccgdm edge drawing to always use face griddata rather than edge data, since edge data is not updated during sculpting.
Fixed bug #24239, "Fkey doesn't work in image paint unless also in 3D texture paint"
* Fixed brush cursor not showing when painting in the image editor without 3d texture painting enabled
* Fixed fkey not working when not in 3d texture paint
Note:
This does not handle showing the brush cursor when reloading a file saved with image painting on but 3d texture painting off. The method used for object paint modes doesn't apply quite the same here, so I left that alone for now.
Reported and patched by Shane Ambler.
Took the opportunity to silence warnings in readfile.c. For Windows in SCons I enabled /WX
for blenloader. This means that all enabled warnings will throw errors from now on.
* The problem is that shadow pass is derived from the diffuse pass as
shad = shad'/diff, where shad' = shad*diff. In cases where diff is
0 and the division can't be done shad is left as shad' (=0).
* This all works just fine until the diffuse color is 0 on just one
channel (no red in material color for example). In this case the shadow
pass is left as 0 too regardless of the existence of an actual shadow,
so the end result is a colored shadow!
* The only real solution is to use the original shadow intensity to
determine if there actually is a shadow or not. This is now stored in
shr->shad[3] from the lamp shadow calculation.
Note: The best solution would probably be to calculate the shadow pass on
it's own and not to derive it from the diffuse pass, but I didn't dare to
start messing up the shading code totally.
slight change to how transform calculates the center of each bezier handle selection.
- selecting both handles but not the knot now uses the mid point between the 2, before it used the handle.
- selecting 1 handle of a curve was still setting td->center to be the knot, now use the handles location only if its selected.
Drawing the view axis went to a lot of trouble to create a color which didnt look very good if the grid had a color other then grey set.
Simplify the function and just use the same colors as the manipulator, also use 2px fixed line width.
the cu->ctime was never set if the frame wasnt changed, so adding a curve and parenting could be done without a frame change leaving the cu->ctime value at zero.
changing the frame or rendering after this would make the parent relationship jump.
Set the curve->ctime in object_handle_update(), this way its set on file load and when linking in new curves.
Another option is to do this when parenting but probably this would miss other cases where its needed.
