2019-08-27Cycles: Stitching of subdivided and displaced meshesMai Lavelle
This patch stitches the vertices along patch edges so that cracks can no longer form when applying subdivision or displacement a mesh. Subpatches are now formed in a way that ensures vertex indices along subpatch edges are equal for adjacent subpatches. A mapping of vertices along patch edges is built to preform stitching. Overall performance is roughly the same, some gains were made in splitting, but some was lost in stitching. This fixes: - T49049 (cracks between patches from material and uv seams) - T49048 (discontinuous normals with true displacement) Reviewers: sergey, brecht Differential Revision: https://developer.blender.org/D3692
2019-08-21Shading: Add more operators to Vector Math node.OmarSquircleArt
Add Multiply, Divide, Project, Reflect, Distance, Length, Scale, Snap, Floor, Ceil, Modulo, Fraction, Absolute, Minimum, and Maximum operators to the Vector Math node. The Value output has been removed from operators whose output is a vector, and the other way around. All of those removals has been handled properly in versioning code. The patch doesn't include tests for the new operators. Tests will be added in a later patch. Reviewers: brecht, JacquesLucke Differential Revision: https://developer.blender.org/D5523

2019-04-16CMake: cleanup, arg rename, add definitions lastCampbell Barton
2019-02-01Cleanup: remove redundant, invalid info from headersCampbell Barton
BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.
2018-11-09Cycles: Cleanup, space after (void)Sergey Sharybin
It was used in like 95% of places.
2018-11-09Cycles: Cleanup, split array from vectorSergey Sharybin
Those are similar but different types, no reason to keep their definitions in a single file.
2018-11-09Cycles: Cleanup, spacing after preprocessorSergey Sharybin
It is supposed to be two spaces before comment stating which if else/endif statements corresponds to. Was mainly violated in the header guards.

2018-02-04msvc: Use source folder structure for project file.Ray Molenkamp
This patch changes the huge list of projects in visual studio into a nice tree matching the source folder structure. see D2823 for details. Differential Revision: http://developer.blender.org/D2823
2018-01-19Cycles: Remove unneeded include statementsSergey Sharybin
Also try to move them from headers to implementation files as much as possible.
2017-03-29Cycles: Make all #include statements relative to cycles source directorySergey Sharybin
The idea is to make include statements more explicit and obvious where the file is coming from, additionally reducing chance of wrong header being picked up. For example, it was not obvious whether bvh.h was refferring to builder or traversal, whenter node.h is a generic graph node or a shader node and cases like that. Surely this might look obvious for the active developers, but after some time of not touching the code it becomes less obvious where file is coming from. This was briefly mentioned in T50824 and seems @brecht is fine with such explicitness, but need to agree with all active developers before committing this. Please note that this patch is lacking changes related on GPU/OpenCL support. This will be solved if/when we all agree this is a good idea to move forward.

2016-10-24Cycles: Cleanup, styleSergey Sharybin
2016-08-24Cycles Standalone: Fix support for subdivision meshesMai Lavelle
Changes from microdisplacement work broke previous support for subdivision meshes, sometimes leading to crashes; this makes things work again. Files that contain "patch" nodes will need to be updated to use meshes instead, as specifying patches was both inefficient and completely unsupported by the new subdivision code.
2016-08-18Code cleanup to use array.data() rather than &array[0]Brecht Van Lommel
(Now without the build errors)
2016-08-18Revert "Code cleanup to use array.data() rather than &array[0]."Mai Lavelle
This reverts commit 40b367479c6fe23d6f2b6d822f2d5266485619f3. Didn't build or solve any known issue. Please don't push changes without testing them first.
2016-08-18Code cleanup to use array.data() rather than &array[0].Brecht Van Lommel
These latter can cause MSVC debug asserts if the array is empty. With C++11 we'll be able to do this for std::vector later. This hopefully fixes an assert in the Cycles subdivision code.
2016-08-14Cycles microdisplacement: Move call to tessellate() from addon to CyclesMai Lavelle
By calling `tessellate()` from the mesh manager in Cycles we can do pre/post processing or even threaded tessellation without concerning client side code with the details.
2016-08-08Cycles: Quiet warning with WITH_OPENSUBDIV disabledJulian Eisel
Checked with @maiself, for now going with this simple solution.
2016-08-07Cycles microdisplacement: Support for Catmull-Clark subdivision via OpenSubdivMai Lavelle
Enables Catmull-Clark subdivision meshes with support for creases and attribute subdivision. Still waiting on OpenSubdiv to fully support face varying interpolation for subdividing uv coordinates tho. Also there may be some inconsistencies with Blender's subdivision which will be resolved at a later time. Code for reading patch tables and creating patch maps is borrowed from OpenSubdiv.

2016-07-29Cycles microdisplacement: ngons and attributes for subdivision meshesMai Lavelle
This adds support for ngons and attributes on subdivision meshes. Ngons are needed for proper attribute interpolation as well as correct Catmull-Clark subdivision. Several changes are made to achieve this: - new primitive `SubdFace` added to `Mesh` - 3 more textures are used to store info on patches from subd meshes - Blender export uses loop interface instead of tessface for subd meshes - `Attribute` class is updated with a simplified way to pass primitive counts around and to support ngons. - extra points for ngons are generated for O(1) attribute interpolation - curves are temporally disabled on subd meshes to avoid various bugs with implementation - old unneeded code is removed from `subd/` - various fixes and improvements Reviewed By: brecht Differential Revision: https://developer.blender.org/D2108
2016-06-07Cycles: Fix regression introduced in c96a4c8Mai Lavelle
A few places still needed to be updated to use the new Mesh::num_triangles() method; wrong number from triangles.size() was causing crashes.

Almost in all cases we want such constructors to be explicit, there are exceptions but only in few places.
2016-04-18Cycles microdisplacement: add max subdivision settingMai Lavelle
This is to prevent situations such as when the camera gets very close to a mesh and causes it to be tessellated into an excessive amount of micropolygons. In REYES this is known as the eye-splits problem. Reviewed By: brecht Differential Revision: https://developer.blender.org/D1922

This way we prevent cracks in the model due to discontinuous normals, by using smooth normals for displacement instead of always getting flat normals after linear subdivision. Reviewed By: brecht Differential Revision: https://developer.blender.org/D1916

2016-02-03Cycles: Cleanup, indentation and bracesSergey Sharybin
2016-01-14Cycles: Reduce scope of some defines set in CMakeListsSergey Sharybin
Should be no functional changes at all, just speeds up re-compilation when some features needs to be disabled for development purposes. For example, when running lots of Valgrind it's handy to disable any GPU devices because otherwise you'll be wasting quite some time in the driver while enumerating devices.

2015-03-27Cycles: Code cleanup, spaces around keywordsSergey Sharybin
This inconsistency drove me totally crazy, it's really confusing when it's inconsistent especially when you work on both Cycles and Blender sides. Shouldn;t cause merge PITA, it's whitespace changes only, Git should be able to merge it nicely.

2013-11-28Cycles: experimental OpenSubdiv code.Brecht Van Lommel
This code can't actually be enabled for building and is incomplete, but it's here because we know we want to support this at some point and there's not much reason to have it in a separate branch if a simple #ifdef can disable it.
2013-11-28Cycles: add ptex face ID and UV attributes.Brecht Van Lommel
Not the most memory efficient way to store these things but it's simple and implementing it better requires some work to natively support subd grids as a primitive in some way.
2013-11-28Cycles: remove approximate subdivision surface with gregory patches code.Brecht Van Lommel
It was never fully implemented and will be replaced by OpenSubdiv. Only linear subdivision remains now. Also includes some refactoring in the split/dice code, adding a SubdParams struct to pass around parameters more easily.
2013-08-18Cycles: relicense GNU GPL source code to Apache version 2.0.Brecht Van Lommel

2013-06-04Cycles:Thomas Dinges
* Revert r57203 (len() renaming) There seems to be a problem with nVidia OpenCL after this and I haven't figured out the real cause yet. Better to selectively enable native length() later, after figuring out what's wrong. This fixes [#35612].
2013-06-03Cycles / Math functions:Thomas Dinges
* Rename some math functions: len -> length len_squared -> length_squared normalize_len -> normalize_length * This way OpenCL uses its inbuilt length() function, rather than our own. The other two functions have been renamed for consistency. * Tested CPU, CUDA and OpenCL compile, should be no functional changes.
2013-05-12Cycles / Math:Thomas Dinges
* Add M_2PI_F and M_4PI_F constants and use them inside the codebase.
