2022-02-10GPencil: Update-on-write using update cacheFalk David
This implements the update cache described in T95401. The cache is currently only used for drawing strokes and sculpting (using the push brush). **Note: Making use of the cache throughout grease pencil will have to be done incrementally in other patches. ** The update cache stores what elements have changed in the original data-block since the last time the eval object was updated. Additionally, the update cache can store multiple updates to the data and minimizes the number of elements that need to be copied. Elements can be tagged using `BKE_gpencil_tag_full_update` and `BKE_gpencil_tag_light_update`. A full update means that the element itself will be copied but also all of the content inside. E.g. when a layer is tagged for a full update, the layer, all the frames inside the layer and all the strokes inside the frames will be copied. A light update means that only the properties of the element are copied without any of the content. E.g. if a layer is tagged with a light update, it will copy the layer name, opacity, transform, etc. When the update cache is in use (e.g. elements have been tagged) then the depsgraph will not trigger a copy-on-write, but an update-on-write. This means that the update cache will be used to determine what elements have changed and then only those elements will be copied over to the eval object. If the update cache is empty or the data block was tagged with a full update, we always fall back to a copy-on-write. Currently, the update cache is only used by the active depsgraph. This is because we need to free the update cache after an update-on-write so it's reset and we need to make sure it is not freed or read by other depsgraphs.

2022-02-08Fix T91253: Slow pose bone selection with many bonesCampbell Barton
Viewport cull bones during selection to avoid depth-picking reading the depth buffer for bones that aren't in the viewport. Files with thousands of bones could hang blender for seconds while selecting. The issue could still happen with overlapping bones or when zoomed out so all bones are under the cursor, however in practice this rarely happens. Now files with many bones select quickly. Related changes include: - Split `BKE_pchan_minmax` out of `BKE_pose_minmax`. - Add `mat3_to_size_max_axis` to return the length of the largest axis (used for scaling the radius).

2022-01-28DrawManager: Image engine support huge images.Jeroen Bakker
Adding better support for drawing huge images in the image/uv editor. Also solved tearing artifacts. The approach is that for each image/uv editor a screen space gpu texture is created that only contains the visible pixels. When zooming or panning the gpu texture is rebuild. Although the solution isn't memory intensive other parts of blender memory usage scales together with the image size. * Due to complexity we didn't implement partial updates when drawing images tiled (wrap repeat). This could be added, but is complicated as a change in the source could mean many different changes on the GPU texture. The work around for now is to tag all gpu textures to be dirty when changes are detected. Original plan was to have 4 screen space images to support panning without gpu texture creation. For now we don't see the need to implement it as the solution is already fast. Especially when GPU memory is shared with CPU ram.

Changes to recent addition: c85c52f2ce478ab0e30c5e93fd5a5cb812db232f. Having both BLI_paths_equal and BLI_path_cmp made it ambiguous which should be used, as `BLI_paths_equal` wasn't the equivalent to `BLI_path_cmp(..) == 0` as it is for string equals macro `STREQ(..)`. It's also a more specialized function which is not used for path comparison throughout Blender's internal path handling logic. Instead rename this `BLI_path_cmp_normalized` and return the result of `BLI_path_cmp` to make it clear paths are modified before comparison. Also add comments about the conventions for Blender's path comparison as well as a possible equivalent to Python's `os.path.samefile` for checking if two paths point to the same location on the file-system.

2022-01-27USD Preview Surface material export.Michael Kowalski
Add `USD Preview Surface From Nodes` export option, to convert a Principled BSDF material node network to an approximate USD Preview Surface shader representation. If this option is disabled, the original material export behavior is maintained, where viewport setting are saved to the Preview Surface shader. Also added the following options for texture export. - `Export Textures`: If converting Preview Surface, export textures referenced by shader nodes to a 'textures' directory which is a sibling of the USD file. - `Overwrite Textures`: Allow overwriting existing texture files when exporting textures (this option is off by default). - `Relative Texture Paths`: Make texture asset paths relative to the USD. The entry point for the new functionality is `create_usd_preview_surface_material()`, called from `USDAbstractWriter::ensure_usd_material()`. The material conversion currently handles a small subset of Blender shading nodes, `BSDF_DIFFUSE`, `BSDF_PRINCIPLED`, `TEX_IMAGE` and `UVMAP`. Texture export is handled by copying texture files from their original location to a `textures` folder in the same directory as the USD. In-memory and packed textures are saved directly to the textures folder. This patch is based, in part, on code in Tangent Animation's USD exporter branch.

2022-01-13Refactor: Move normals out of MVert, lazy calculationHans Goudey
As described in T91186, this commit moves mesh vertex normals into a contiguous array of float vectors in a custom data layer, how face normals are currently stored. The main interface is documented in `BKE_mesh.h`. Vertex and face normals are now calculated on-demand and cached, retrieved with an "ensure" function. Since the logical state of a mesh is now "has normals when necessary", they can be retrieved from a `const` mesh. The goal is to use on-demand calculation for all derived data, but leave room for eager calculation for performance purposes (modifier evaluation is threaded, but viewport data generation is not). **Benefits** This moves us closer to a SoA approach rather than the current AoS paradigm. Accessing a contiguous `float3` is much more efficient than retrieving data from a larger struct. The memory requirements for accessing only normals or vertex locations are smaller, and at the cost of more memory usage for just normals, they now don't have to be converted between float and short, which also simplifies code In the future, the remaining items can be removed from `MVert`, leaving only `float3`, which has similar benefits (see T93602). Removing the combination of derived and original data makes it conceptually simpler to only calculate normals when necessary. This is especially important now that we have more opportunities for temporary meshes in geometry nodes. **Performance** In addition to the theoretical future performance improvements by making `MVert == float3`, I've done some basic performance testing on this patch directly. The data is fairly rough, but it gives an idea about where things stand generally. - Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms), showing that accessing just `MVert` is now more efficient. - Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight change that at least shows there is no regression. - Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small but observable speedup. - Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms), shows that using normals in geometry nodes is faster. - Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms), shows that calculating normals is slightly faster now. - File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB), Normals are not saved in files, which can help with large meshes. As for memory usage, it may be slightly more in some cases, but I didn't observe any difference in the production files I tested. **Tests** Some modifiers and cycles test results need to be updated with this commit, for two reasons: - The subdivision surface modifier is not responsible for calculating normals anymore. In master, the modifier creates different normals than the result of the `Mesh` normal calculation, so this is a bug fix. - There are small differences in the results of some modifiers that use normals because they are not converted to and from `short` anymore. **Future improvements** - Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier already retrieves normals if they are needed anyway. - Copy normals as part of a better CoW system for attributes. - Make more areas use lazy instead of eager normal calculation. - Remove `BKE_mesh_normals_tag_dirty` in more places since that is now the default state of a new mesh. - Possibly apply a similar change to derived face corner normals.

2022-01-12BLI: Refactor vector types & functions to use templatesClément Foucault
This patch implements the vector types (i.e:`float2`) by making heavy usage of templating. All vector functions are now outside of the vector classes (inside the `blender::math` namespace) and are not vector size dependent for the most part. In the ongoing effort to make shaders less GL centric, we are aiming to share more code between GLSL and C++ to avoid code duplication. ####Motivations: - We are aiming to share UBO and SSBO structures between GLSL and C++. This means we will use many of the existing vector types and others we currently don't have (uintX, intX). All these variations were asking for many more code duplication. - Deduplicate existing code which is duplicated for each vector size. - We also want to share small functions. Which means that vector functions should be static and not in the class namespace. - Reduce friction to use these types in new projects due to their incompleteness. - The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a bit of a let down. Most clases are incomplete, out of sync with each others with different codestyles, and some functions that should be static are not (i.e: `float3::reflect()`). ####Upsides: - Still support `.x, .y, .z, .w` for readability. - Compact, readable and easilly extendable. - All of the vector functions are available for all the vectors types and can be restricted to certain types. Also template specialization let us define exception for special class (like mpq). - With optimization ON, the compiler unroll the loops and performance is the same. ####Downsides: - Might impact debugability. Though I would arge that the bugs are rarelly caused by the vector class itself (since the operations are quite trivial) but by the type conversions. - Might impact compile time. I did not saw a significant impact since the usage is not really widespread. - Functions needs to be rewritten to support arbitrary vector length. For instance, one can't call `len_squared_v3v3` in `math::length_squared()` and call it a day. - Type cast does not work with the template version of the `math::` vector functions. Meaning you need to manually cast `float *` and `(float *)[3]` to `float3` for the function calls. i.e: `math::distance_squared(float3(nearest.co), positions[i]);` - Some parts might loose in readability: `float3::dot(v1.normalized(), v2.normalized())` becoming `math::dot(math::normalize(v1), math::normalize(v2))` But I propose, when appropriate, to use `using namespace blender::math;` on function local or file scope to increase readability. `dot(normalize(v1), normalize(v2))` ####Consideration: - Include back `.length()` method. It is quite handy and is more C++ oriented. - I considered the GLM library as a candidate for replacement. It felt like too much for what we need and would be difficult to extend / modify to our needs. - I used Macros to reduce code in operators declaration and potential copy paste bugs. This could reduce debugability and could be reverted. - This touches `delaunay_2d.cc` and the intersection code. I would like to know @howardt opinion on the matter. - The `noexcept` on the copy constructor of `mpq(2|3)` is being removed. But according to @JacquesLucke it is not a real problem for now.

It it rather an old experiment now which didn't pay off. The initial idea was to have main and jobs threads on fast nodes of TR2 processors. This didn't really work reliably because in Blender we need to be able to create nested threads without their affinity set. This is not how some of OS are creating nested threads, and we don't always have access to child threads to reset their affinity. So overall complexity of the initial idea implementation became too much compared to the performance gain.

2022-01-03UDIM: Support virtual filenamesJesse Yurkovich
This implements the design detailed in T92696 to support virtual filenames for UDIM textures. Currently, the following 2 substitution tokens are supported: | Token | Meaning | | ----- | ---- | | <UDIM> | 1001 + u-tile + v-tile * 10 | | <UVTILE> | Equivalent to u<u-tile + 1>_v<v-tile + 1> | Example for u-tile of 3 and v-tile of 1: filename.<UDIM>_ver0023.png --> filename.1014_ver0023.png filename.<UVTILE>_ver0023.png --> filename.u4_v2_ver0023.png For image loading, the existing workflow is unchanged. A user can select one or more image files, belonging to one or more UDIM tile sets, and have Blender load them all as it does today. Now the <UVTILE> format is "guessed" just as the <UDIM> format was guessed before. If guessing fails, the user can simply go into the Image Editor and type the proper substitution in the filename. Once typing is complete, Blender will reload the files and correctly fill the tiles. This workflow is new as attempting to fix the guessing in current versions did not really work, and the user was often stuck with a confusing situation. For image saving, the existing workflow is changed slightly. Currently, when saving, a user has to be sure to type the filename of the first tile (e.g. filename.1001.png) to save the entire UDIM set. The number could differ if they start at a different tile etc. This is confusing. Now, the user should type a filename containing the appropriate substitution token. By default Blender will fill in a default name using the <UDIM> token but the user is free to save out images using <UVTILE> if they wish. Differential Revision: https://developer.blender.org/D13057

2021-12-17Allocator: simplify using guarded allocator in C++ codeJacques Lucke
Using the `MEM_*` API from C++ code was a bit annoying: * When converting C to C++ code, one often has to add a type cast on returned `void *`. That leads to having the same type name three times in the same line. This patch reduces the amount to two and removes the `sizeof(...)` from the line. * The existing alternative of using `OBJECT_GUARDED_NEW` looks a out of place compared to other allocation methods. Sometimes `MEM_CXX_CLASS_ALLOC_FUNCS` can be used when structs are defined in C++ code. It doesn't look great but it's definitely better. The downside is that it makes the name of the allocation less useful. That's because the same name is used for all allocations of a type, independend of where it is allocated. This patch introduces three new functions: `MEM_new`, `MEM_cnew` and `MEM_delete`. These cover the majority of use cases (array allocation is not covered). The `OBJECT_GUARDED_*` macros are removed because they are not needed anymore. Differential Revision: https://developer.blender.org/D13502

Saving with only a filename (from Python) wasn't being prevented, while it would successfully write the file to the working-directory, path remapping and setting relative paths wouldn't work afterwards as `Main.filepath` would have no directory component. Disallow this since it's a corner case which only ever occurs when path names without any directories are used from Python, the overhead of expanding the working-directory for all data saving operations isn't worthwhile.

Previously it would write to "untitled.blend" and set the `G.main->filepath` to this as well. - bpy.ops.wm.save_mainfile(filepath="untitled.blend") fails & reports and error as the filename has no directory component. - `BLI_path_is_abs_from_cwd` was added to check if the path would attempt to expand to the CWD.
