* create() and destroy() are deprecated since OSL 1.5, use regular constructors / destructors.

Reported and nailed down by Michale (MeshLogic).
The code that fixes this was commented out, but Brecht gave the go ahead to use it even if it is not the real solution

The issue was caused by the whole viewplane used for mapping calculation
which would for sure lead to differences between final camera render and
viewport render from the camera view.
This commit makes it so window texture mapping is the same as final render
when viewing from the camera in viewport render.
It's not totally clear what's the right thing to do when viewport is not
in the camera view mode and that part is left unchanged.

Looks like with some versions of Xlib (at least the 1.6.2 currently used on Debian testing)
and/or evdev generic driver (2.9.0 currently on Debian testing), you have to also 'select'
DeviceButton1Motion with the extended tablet's motion event, otherwise you won't get any
tablet motion event once pen is pressed, leading to no pressure (each stroke keeping its
init pressure until the end). Crap!

This is the same as blender internal's texture mapping from another object,
so this way it's possible to control texture space of one object by another.
Quite straightforward change apart from the workaround for the stupidness of
the dependency graph. Now shader has flag telling that it depends on object
transform. This is the simplest way to know which shaders needs to be tagged
for update when object changes. This might give some false-positive tags now
but reducing them should not be priority for Cycles and rather be a priority
to bring new dependency graph.
Also GLSL preview does not support using other object for mapping.
This is actually correct for BI shading as well and to be addressed as
a part of general GLSL viewport improvements since it's not really clear
how to support this in GLSL.

This commit makes it so blackbody and beckmann lookup tables are stored on CPU
after being generated and then only being copied to the device if needed.
This solves lag of viewport update when tweaking shader tree by using 266KB of
CPU memory.

Not sure why this was not visible previously, but the change is
logical anyway.

When doing BVH leaf node split we can't rely on leaf size limit from
BVH parameters in case there's spatial split enabled.
This commit basically reverts previous optimization change here which
used stack-allocated memory and uses heap-allocated vector now.
It's possible to boost this code up again by using own allocator.

Handy for troubleshooting.

Root of the issue goes to the fact that since the very beginning Cycles was
using ZYX euler rotation for mapping shader node but blender was always
using XYZ euler rotation.
This commit switches Cycles to use XYZ euler order and adds versioning code
to preserve backward compatibility.
There was no really nice solution here because either we're ending up with
versioning code or we'll need to deal with all sort of exceptions from blender
side in order to support ZYX order for the mapping node. The latest one is
also creepy from the other render engines points of view -- that might break
compatibility with existing bindings or introduce some extra headache for them
in the future.
This could also become a PITA for us with need of supporting all sort of weird
and wonderful exceptions in the refactored viewport project.
NOTE: This commit breaks forward compatibility, meaning opening new files in
older blender might not give proper result if Mapping node was used.
Also, libraries are to be re-saved separately from the scene file, otherwise
versioning code for them wouldn't run if scene file was re-saved with new
version of blender.

This way Cycles finally becomes feature-full on image projections
compared to Blender Internal and Gooseberry Project Team could
finally finish the movie.

* If a Background node is set to a black color or zero strength,
it now gets removed from the shader graph.
* In case the graph is empty (no background node), the kernel will skip
evaluating it and save some rendertime. This can help quite a bit in scenes,
where the majority of the image consists of a black background.
Example: http://www.pasteall.org/pic/show.php?id=82650
In this case the render is ~16% faster.

Please note that opennl is already modified (for double precision)
so re-integration is not really easy. Also, we'll eventually switch
to Eigen.
For until that let's just solve the condition in our bundled opennl.

Issue seems to be caused by not totally proper pdf and eval values for this
closure. Changed it so they reflect to ggx/beckmann reflection with roughness
set to 0, which is effectively the same as the sharp reflection.
|

Issue was, when requesting (building) lnors for a mesh that has
autosmooth disabled, one would expect to simply get vnors as lnors.
Until now, it wasn't the case, which was bad e.g. for normal projections
of loops in recent remap code (projecting along split loop normals
when you would expect projection along vertex normals...).
Also, removed the 'angle' parameter from RNA's `mesh.calc_normals_split`.
This should *always* use mesh settings (both autosmooth and smoothresh),
otherwise once again we'd get inconsistencies in some cases.
Will update fbx and obj addons too.

The check should also become aware of the fact were using clipping plane
instead of clipping sphere now.

Issue was caused by wrong order of scene device update, which could
lead to missing object flags in shader kernel.
This patch solves a bit more than that making sure objects flags are
always properly updated, so adding/removing volume BSDF will properly
reflect on viewport where camera might become being in volume and so.
|
|
Also add missing render_time initialization in progress.
|
|
Also adds safe-area presets.

They went back from string_view to string for compiler options.
Still having linking errors here, but maybe others will be more lucky to fully
compiler blender with new OSL.

This commit basically makes it so statistics print from different BVH trees are not
being interleaved with each other. Glog ensures this when debug print is done as a
single put to stream operator.

Since leaf node gets split further into per-primitive type leaves old check
for number of curves became a bit ridiculous -- it might lead to two leaf nodes
each of which would contain only one curve primitive (one motion curve and one
regular curve).
This lead to quite dramatic slowdown for Victor model -- around 40%, which is
totally unacceptable.
This commit is aimed to prevent such situation and from quick render test it
seems victor is now back to normal render time. Further testing is needed tho.
There are also other ideas about splitting the node, will need to look into
them next.

Just wrong constant used, names are indeed too close to each other.

This patch adds the option to set minimum/maximum latitude/longitude values for
the equirectangular panorama camera in Cycles, as discussed in T34400.
The separate functions in kernel_projection.h are needed because the regular
ones are also used as helper functions for environment map sampling.

This patch makes Cycles ignore the time spent in BVH construction etc. when
estimating the remaining time. Considering that the remaining time is calculated
based on the average time per tile so far, as far as I understand it makes no
sense to include the preprocessing time.

There seems to be inconsistency in flags checks in Cycles kernel. In the interface
glossy means "Glossy Reflection" and it is properly taken into account when doing
visibility check in BVH traversal.
The check in indirect background/light emission was treating this flags as "any of
glossy reflection or transmission" which is kind of weird.
Made it so emission code follows ray visibility assumptions in other parts of the
kernel now.

Basically the title tells it all, now Cycles uses proper clipping plane,
matching other render engines.

Really stupid issue caused by typo in bitfield bit lead to bit conflict,
Not sure how it was done, could be some bad merge conflict resolve in the
original commit or just pure man stupidnes.
This is a nice example when having set of small test render scenes hooked
to the ctest would really help.
It's probably not that stopper issue (even tho still quite bad) since it
was made 2 months ago. But if we ever do 'a' this time it's a nice change
to include.

It's apparently not nice to access 0th element of zero-size vector in C++.

Overview this in one of the previous BVH commits.

This way we'll notice that leaf splitting didn't happen correct pretty easily
in debug builds.
There'll be absolutely no impact on release builds.

This commit enables BVH leaf nodes split by the primitive type and makes it
so BVH traversal code is now aware and benefits from this.
As was mentioned in original commit, this change is crucial to be able to do
single ray to multiple triangle intersection. But it also appears to give
barely visible speedup in some scene.
In any case there should be no noticeable slowdown, and this change is what
we need to have anyway.
|
|
Use variables allocated in the stack and avoid heap allocation which should make
leaf splitting code a bit faster.
|
|
The idea of this change is make it possible to split leaf nodes by primitive
type, making leaf containing primitives of the same type.
This would become handy when working on a single ray to multiple triangles
intersection code, plus with careful implementation it might give some extra
benefits on BVH traversal code by avoiding primitive type fetch and check for
each primitive in the node. But that's a bit tricky to have benefits on this
change only because depth of BVH increases.
This option is not exposed to the interface at all and not used even secretly,
the commit is only needed to help working further in this direction without
messing around with local patches and worrying of them running out of date.
