From 8197a611fae29713a8096f5798bee65b8dae30c6 Mon Sep 17 00:00:00 2001 From: Gordon MacPherson Date: Tue, 20 Oct 2020 18:00:16 +0100 Subject: [PATCH] Rewrite FBX Importer to convert directly to Godot scene format Co-authored-by: Gordon MacPherson Co-authored-by: Andrea Catania Co-authored-by: K. S. Ernest (iFire) Lee This is a complete rewrite of the importer. It will give more deterministic behaviour and has been sponsored by IMVU inc, over 1 year has gone into the development of this importer to remove the burden of the FBX SDK. This was my project for 1 entire year and I really enjoyed the opportunity to add to Godot. Along the road of implementing fixes we implemented fbx pivots, animations and inheritance type handling, which in most cases works properly. We have implemented animation and mesh skinning too this should work out of the box, if there are issues let us know. It's designed so that you can expand this with ease, and fix bugs easily too. It can import from Autodesk Maya and import into Godot, with pivots. There are bits we could polish but for now this is good enough. Additional fixes made before upstreaming: - fixed memory leaks - ensure consistent ordering on mac linux and windows for fbx tree. (very important for material import to be deterministic) - disabled incorrect warnings for fbx_material - added compatibility code for /RootNode/ so compat is not broken - Optimise FBX - directly import triangles - remove debug messages - add messages for mesh id, mesh re-import is sometimes slow and we need to know what mesh is being worked on - Document no longer uses unordered maps - Removed some usages of &GetRequiredToken replaced with safe *GetRequiredToken() function - Added parser debugging - Added ERR_FAIL_CONDS for unsupported mesh formats (we can add these later super easy to do now) - Add memory debugging for the Tokens and the TokenParser to make it safe - Add memory initialisation to mesh.cpp surface_tool.h and mesh.h - Initialise boolean flags properly - Refactored to correct naming for the fbx_mesh_data.h so you know what data you are working on - Disabled corruption caused by the FIXME: - Fixed document reading indexes and index_to_direct vs indexes mode - Fixed UV1 and UV2 coordinates - Fixed importer failing to import version 7700 files - Replaced memory handling in the FBX Document with pointers, before it was dereferencing invalid memory. - Fixed typed properties - Improved Document API - Fixed bug with ProcessDOMConnection() not working with the bool flag set to true. - Fixed FBX skinning not deforming for more than one single mesh - Fixed FBX skeleton mapping and skin mapping not being applied properly (now retrieved from document skin list) - Fixed set_bone_pose being used in final version() - Fixed material properties exceeding 1.0. - FBX Document parser revamped to use safe memory practices, and with graceful error messages. - ScopePtr, TokenPtr and various internal types have been fleshed out to use proper typedefs across the codebase. - Fixed memory leaks caused by token cleanup failing (now explicit cleanup step, no shared_ptr, etc) - Fixed bug with PropertyTable not reading all properties and not cleaning up properly. - Fixed smoothing groups not working - Fixed normal duplications - Fixed duplication check for pre-existing coordinates. - Fixed performance of vertex lookup in large meshes being slow, using lookup table separate to the data for indexing, this reduces import time from 10 minutes of bistro down to 30 seconds. - Fixed includes requiring absolute path in headers and cpp files using CPPPath. Bugs/Features wish list: - locator bones - quat anim key interpolation (most fbx maya files have euler rotations from blender and maya, nobody uses this) - some rigs skins scale up when SSC enabled inconsistently per bone - some skins can disappear entirely - material mapping needs expanded, but this will be done for 4.0 as it requires rewrite. Workarounds for issues found until we patch them: - mesh -> clear skin can resolve most of the bugs above. - locators can be worked around by removing them before exporting your rig. - some material properties wont always import, this is okay to override in the material properties. **If you are having issues or need support fear not!** Please provide minimal rigs which can reproduce issues as we can't spend a lot of time investigating each rig. We need a small example which breaks and we can then sort the problem. In some cases this is not possible so its okay to privately send models to us via IRC or a ticket and we can provide an email address, we won't reveal or disclose privately sent rig files to any companies, or to companies I work for, they will not be shared, only tested and bugs will be drawn up from the conclusions. Also include identifying information about what you did and how it didn't work. Please file each file separately in a bug report, unless the problem is the same. This was sponsored by IMVU, and a special thanks to everyone who supported this project.

The focus for the binary format -(.assbin) is fast loading. Optional deflate compression helps reduce file size. The XML -flavour, .assxml or simply .xml, is just a plain-to-xml conversion of aiScene. - -ASSBIN is Assimp's binary interchange format. assimp_cmd (<root>/tools/assimp_cmd) is able to -write it and the core library provides a loader for it. - -@section assxml XML File format - -The format is pretty much self-explanatory due to its similarity to the in-memory aiScene structure. -With few exceptions, C structures are wrapped in XML elements. - -The DTD for ASSXML can be found in <root>/doc/AssXML_Scheme.xml.

But for most developers its likely - * useful just for programming sanity. - * - * The problem is that some compiler vendors chose to ignore the C99 - * standard and some older compilers have no opportunity to be updated. - * Because of this situation, simply including stdint.h in your code - * makes it unportable. - * - * So that's what this file is all about. Its an attempt to build a - * single universal include file that works on as many platforms as - * possible to deliver what stdint.h is supposed to. Even compilers - * that already come with stdint.h can use this file instead without - * any loss of functionality. A few things that should be noted about - * this file: - * - * 1) It is not guaranteed to be portable and/or present an identical - * interface on all platforms. The extreme variability of the - * ANSI C standard makes this an impossibility right from the - * very get go. Its really only meant to be useful for the vast - * majority of platforms that possess the capability of - * implementing usefully and precisely defined, standard sized - * integer scalars. Systems which are not intrinsically 2s - * complement may produce invalid constants. - * - * 2) There is an unavoidable use of non-reserved symbols. - * - * 3) Other standard include files are invoked. - * - * 4) This file may come in conflict with future platforms that do - * include stdint.h. The hope is that one or the other can be - * used with no real difference. - * - * 5) In the current version, if your platform can't represent - * int32_t, int16_t and int8_t, it just dumps out with a compiler - * error. - * - * 6) 64 bit integers may or may not be defined. Test for their - * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX. - * Note that this is different from the C99 specification which - * requires the existence of 64 bit support in the compiler. If - * this is not defined for your platform, yet it is capable of - * dealing with 64 bits then it is because this file has not yet - * been extended to cover all of your system's capabilities. - * - * 7) (u)intptr_t may or may not be defined. Test for its presence - * with the test: #ifdef PTRDIFF_MAX. If this is not defined - * for your platform, then it is because this file has not yet - * been extended to cover all of your system's capabilities, not - * because its optional. - * - * 8) The following might not been defined even if your platform is - * capable of defining it: - * - * WCHAR_MIN - * WCHAR_MAX - * (u)int64_t - * PTRDIFF_MIN - * PTRDIFF_MAX - * (u)intptr_t - * - * 9) The following have not been defined: - * - * WINT_MIN - * WINT_MAX - * - * 10) The criteria for defining (u)int_least(*)_t isn't clear, - * except for systems which don't have a type that precisely - * defined 8, 16, or 32 bit types (which this include file does - * not support anyways). Default definitions have been given. - * - * 11) The criteria for defining (u)int_fast(*)_t isn't something I - * would trust to any particular compiler vendor or the ANSI C - * committee. It is well known that "compatible systems" are - * commonly created that have very different performance - * characteristics from the systems they are compatible with, - * especially those whose vendors make both the compiler and the - * system. Default definitions have been given, but its strongly - * recommended that users never use these definitions for any - * reason (they do *NOT* deliver any serious guarantee of - * improved performance -- not in this file, nor any vendor's - * stdint.h). - * - * 12) The following macros: - * - * PRINTF_INTMAX_MODIFIER - * PRINTF_INT64_MODIFIER - * PRINTF_INT32_MODIFIER - * PRINTF_INT16_MODIFIER - * PRINTF_LEAST64_MODIFIER - * PRINTF_LEAST32_MODIFIER - * PRINTF_LEAST16_MODIFIER - * PRINTF_INTPTR_MODIFIER - * - * are strings which have been defined as the modifiers required - * for the "d", "u" and "x" printf formats to correctly output - * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t, - * (u)least32_t, (u)least16_t and (u)intptr_t types respectively. - * PRINTF_INTPTR_MODIFIER is not defined for some systems which - * provide their own stdint.h. PRINTF_INT64_MODIFIER is not - * defined if INT64_MAX is not defined. These are an extension - * beyond what C99 specifies must be in stdint.h. - * - * In addition, the following macros are defined: - * - * PRINTF_INTMAX_HEX_WIDTH - * PRINTF_INT64_HEX_WIDTH - * PRINTF_INT32_HEX_WIDTH - * PRINTF_INT16_HEX_WIDTH - * PRINTF_INT8_HEX_WIDTH - * PRINTF_INTMAX_DEC_WIDTH - * PRINTF_INT64_DEC_WIDTH - * PRINTF_INT32_DEC_WIDTH - * PRINTF_INT16_DEC_WIDTH - * PRINTF_UINT8_DEC_WIDTH - * PRINTF_UINTMAX_DEC_WIDTH - * PRINTF_UINT64_DEC_WIDTH - * PRINTF_UINT32_DEC_WIDTH - * PRINTF_UINT16_DEC_WIDTH - * PRINTF_UINT8_DEC_WIDTH - * - * Which specifies the maximum number of characters required to - * print the number of that type in either hexadecimal or decimal. - * These are an extension beyond what C99 specifies must be in - * stdint.h. - * - * Compilers tested (all with 0 warnings at their highest respective - * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32 - * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio - * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3 - * - * This file should be considered a work in progress.
