IO能力测试
虽然说,Assimp能支持这么多格式,但支持的粒度、完整度,还是要测试的。
构建工程:直接用CMake,构建VS的工程即可。
测试方法¶
assimp_cmd子项目提供了基础的读写示例,通过命令行调用即可调试
测试例子:
- 将assimp_cmd设置为启动项
- 右键assimp_cmd > 属性 > 调试 > 命令参数,输入
info D:\test\assimp-5.0.1\data\assimp-mdb\model-db\Obj\Wuson\WusonOBJ.obj
- 运行即可调试
测试数据:在以下文件目录中有很多模型文件
- assimp-5.0.1\data\assimp-mdb\model-db
- assimp-5.0.1\test\models
参数说明:
const char* AICMD_MSG_HELP =
"assimp <verb> <parameters>\n\n"
" verbs:\n"
" \tinfo - Quick file stats\n"
" \tlistext - List all known file extensions available for import\n"
" \tknowext - Check whether a file extension is recognized by Assimp\n"
#ifndef ASSIMP_BUILD_NO_EXPORT
" \texport - Export a file to one of the supported output formats\n"
" \tlistexport - List all supported export formats\n"
" \texportinfo - Show basic information on a specific export format\n"
#endif
" \textract - Extract embedded texture images\n"
" \tdump - Convert models to a binary or textual dump (ASSBIN/ASSXML)\n"
" \tcmpdump - Compare dumps created using \'assimp dump <file> -s ...\'\n"
" \tversion - Display Assimp version\n"
"\n Use \'assimp <verb> --help\' for detailed help on a command.\n"
;
导入OBJ,输出fbx¶
IFC测试¶
导入IFC,输出fbx
export D:\test\assimp-5.0.1\data\assimp-mdb\model-db\ifc\1.ifc --format=FBX
报错信息
ERROR: Failed to load file: (entity #25) type error reading literal field - expected argument 8 to IfcSpatialStructureElement to be a `IfcElementCompositionEnum`
测试数据中1.ifc,9.ifc比较复杂,都是上面的报错。
对于简单的wall.ifc,没有 IfcSpatialStructureElement
或 IfcElementCompositionEnum
构件类的,就可以读取成功
gltf测试¶
初步测试读写正常
