2021-04-01Fix Cycles build error with "make developer" on some CPUsNikita Sirgienko

2020-11-04Cycles API: encapsulate Node socket membersKévin Dietrich
This encapsulates Node socket members behind a set of specific methods; as such it is no longer possible to directly access Node class members from exporters and parts of Cycles. The methods are defined via the NODE_SOCKET_API macros in `graph/ node.h`, and are for getting or setting a specific socket's value, as well as querying or modifying the state of its update flag. The setters will check whether the value has changed and tag the socket as modified appropriately. This will let us know how a Node has changed and what to update, which is the first concrete step toward a more granular scene update system. Since the setters will tag the Node sockets as modified when passed different data, this patch also removes the various modified methods on Nodes in favor of Node::is_modified which checks the sockets' update flags status.

2020-09-17Tests: bundle tests for some modules in their own executablesBrecht Van Lommel
The ffmpeg, guardedalloc and blenlib are quite isolated and putting them in their own executable separate from blender_test is faster for development than linking the entire blender_tests executable. For Cycles, this also bundles all the unit tests into one executable. Ref T79958 Differential Revision: https://developer.blender.org/D8714

2020-08-04Cycles: Fix nan in decomposed transform for degenerated inputSergey Sharybin
The decomposed transform would have consists of nan values if the input transform had zero scale. Now the decomposition will check for zero scale, and if it is detected then the result will be ensured to be finite. Additionally, rotation value will be copied from previous/next time step to help avoiding obscure interpolation. The latter step can become more comprehensive than the current simple implementation.

2020-02-18Cycles: Fix failing avxf cross test on AVX2Ray Molenkamp
cycles_util_avxf_avx2_test failed on the cross test, since it wasn't immediately clear why, the test was disabled. After looking into it, this test when build for AVX2 is generating FMA instructions where the intermediate results have "infinite" precision [1] leading to slightly different results. This diff re-enables the cross test and allows for a small error in the results.

2019-12-13Cycles: Fix compilation of the Render Graph testLukas Stockner
2019-12-12Add support for tiled images and the UDIM naming schemeLukas Stockner
This patch contains the work that I did during my week at the Code Quest - adding support for tiled images to Blender. With this patch, images now contain a list of tiles. By default, this just contains one tile, but if the source type is set to Tiled, the user can add additional tiles. When acquiring an ImBuf, the tile to be loaded is specified in the ImageUser. Therefore, code that is not yet aware of tiles will just access the default tile as usual. The filenames of the additional tiles are derived from the original filename according to the UDIM naming scheme - the filename contains an index that is calculated as (1001 + 10*<y coordinate of the tile> + <x coordinate of the tile>), where the x coordinate never goes above 9. Internally, the various tiles are stored in a cache just like sequences. When acquired for the first time, the code will try to load the corresponding file from disk. Alternatively, a new operator can be used to initialize the tile similar to the New Image operator. The following features are supported so far: - Automatic detection and loading of all tiles when opening the first tile (1001) - Saving all tiles - Adding and removing tiles - Filling tiles with generated images - Drawing all tiles in the Image Editor - Viewing a tiled grid even if no image is selected - Rendering tiled images in Eevee - Rendering tiled images in Cycles (in SVM mode) - Automatically skipping loading of unused tiles in Cycles - 2D texture painting (also across tiles) - 3D texture painting (also across tiles, only limitation: individual faces can not cross tile borders) - Assigning custom labels to individual tiles (drawn in the Image Editor instead of the ID) - Different resolutions between tiles There still are some missing features that will be added later (see T72390): - Workbench engine support - Packing/Unpacking support - Baking support - Cycles OSL support - many other Blender features that rely on images Thanks to Brecht for the review and to all who tested the intermediate versions!

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.

2019-08-20Cycles Tests: Fix Math tests when use_clamp is true.OmarSquircleArt

2017-01-25[Cycles/MSVC/Testing] Fix broken test code.lazydodo
Currently the tests don't run on windows for the following reasons 1) render_graph_finalize has an linking issue due missing a bunch of libraries (not sure why this is not an issue for linux) 2) This one is more interesting, in test/python/cmakelists.txt ${TEST_BLENDER_EXE_BARE} and ${TEST_BLENDER_EXE} are flat out wrong, but for some reason this doesn't matter for most tests, cause ctest will actually go out and look for the executable and fix the path for you *BUT* only for the command, if you use them in any of the parameters it'll happily pass on the wrong path. 3) on linux you can just run a .py file, windows is not as awesome and needs to be told to run it with pyton. 4) had to use the NAME/COMMAND long form of add_test otherwise $<TARGET_FILE:blender> doesn't get expanded, why? beats me. 5) missing idiff.exe for msvc2015/x64 in the libs folder. This patch addresses 1-4 , but given I have no working Linux build environment, I'm unsure if it'll break anything there 5 has been fixed in rBL61751 Reviewers: juicyfruit, brecht, sergey Reviewed By: sergey Subscribers: Blendify Tags: #cycles, #automated_testing Differential Revision: https://developer.blender.org/D2367

2016-10-01Cycles: implement partial constant folding for exponentiation.Alexander Gavrilov
This is also an important mathematical operation that can be folded if it is known that one argument is a certain constant. For colors the operation is provided as a Gamma node. The SVM Gamma node needs a small fix to make it follow the 0 ^ 0 == 1 rule, same as the Power node, or the Gamma node itself in OSL mode.

2016-08-11Revert "Cycles Tests: Add test for correct 16 byte alignment of KernelData ↵Sergey Sharybin
structs" Using unit tests is a wrong way to control static behavior of the application. They should only be used for checking dynamic behavior, all the rest is easily controllable at compile time. Doing tests at ocmpile time are actually more robust approach since we don't have strict policy of runnign unit tests before accepting any change. Proper alignment control is coming shortly. This reverts commit 7c3a06c34918567e6b0ab67bded60725ff63073b.
