This removes a bunch of animation/driver evaluations and recalc flags that
should be redundant in the new depsgraph, and were incorrectly affecting
the evaluated scene in a permanent way.
Still two cases that could be removed if the depsgraph is improved, in
BKE_object_handle_data_update and BKE_cachefile_update_frame.
For physics subframe interpolation there are also still calls to
BKE_object_where_is_calc that should ideally be removed as well, though
they are not known to cause keyframing bugs.
Differential Revision: https://developer.blender.org/D4274
Only keep this function when drawing to avoid COW overhead that reduce performance.
After some changes I did some time ago, the use of original ID was not required and this only added depsgraph overhead and problems.
This change solves the problems with updates in render mode.
Related to T57484 and the changes requested by Sergey.
Support the alpha channel use of the object color in solid mode.
The Transparency effect is still using the Xray algorithm and not
true Alpha blending.
This adds the posibility of having certain materials transparent in solid
mode. The option is (for now) per material only and thus only shows in
material color mode.
This uses the same rendering technique as Xray mode.
Note that objects are not considered transparent for selection with this.
- Add noise to remove undersampling artifact
- Create 2 mipmaps to the scene color buffer in order to have bigger blurs
- Replace blur2 with a 3x3 median filter that doesn't dilate the highlights
- Use temporal accumulation to remove noise
For some reason all of this exacerbate some bleeding issues happening on
far foreground elements from near foreground elements. The actual problem
was already happening before but was not really noticeable. It needs some
more work to be fixed.
- Compute samples positions on CPU.
- Use 3x3 Box blur instead of 2x2.
- Implement bokeh parameters.
With this commit, dof performance is almost negligeable.
The quality is a bit lower than before but can be improve. Also now big
Circle of confusion are supported (up to 200px).
Cost is ~1.25ms on AMD Vega with a 2560p viewport than full HD and
pretty shallow depth of field.
Coc downsampling and dilation is not used anymore for now (commented).
The algorithm used is borrowed from :
http://tuxedolabs.blogspot.com/2018/05/bokeh-depth-of-field-in-single-pass.html
This makes it possible to have a decent blur for foreground over defocused
background in one pass only.
The algorithm is using a gather approach that is much faster
than the scatter approach used in Eevee. This makes it possible to have
custom bokeh shapes (not implemented yet) which would be impossible with
a separable gaussian technique.
The blur is done in 2 steps. The first one define the shape of the bokeh
and the second that fill the undersampling.
A downsample max-CoC tile texture speed up the gathering process.
Artists requested to show the stroke while drawing a new stroke using a material with fill color only, because it's very difficult to see the stroke.
Now the stroke shows always but using the fill color, not the stroke color because maybe is not set.
Originally I wanted to avoid adding draw manager specific ifdef's all
over generic shaders however this isn't needed in so many places.
Also there are shaders that are only used by the draw manager so
duplicating them only to have the original unused doesn't make sense.
The problem was related to cache data that was removed from memory before the FX finished. This could affect to any FX.
Now all the information is saved in the FX itself in runtime struct to keep memory safe when cache memory is released.
DRW_shader_get_builtin_shader can replace GPU_shader_get_builtin_shader
when we need to support clipping.
Use this for loose point & wire drawing in object mode,
clips edges in lattice edit mode.
