ASSIMP构建大纲:
因为递归的原因有必要把大纲还原,类似katana和maya大纲一样
以maya为例:(输出的时候别导出obj,fbx可以保护层级,abc也可以,但是现在assimp不支持,回头可以用abc api 搞一个)
所以我在函数原型加入一个pwd
void processNode(aiNode * node, const aiScene* scene,string pwd);
#include <iostream> #include <assimp/Importer.hpp> #include <assimp/scene.h> #include <assimp/postprocess.h> #include <string> using namespace std; void processNode(aiNode * node, const aiScene* scene, string pwd); int main(){ Assimp::Importer import; string path = "maya.fbx"; const aiScene * scene = import.ReadFile(path, aiProcess_Triangulate | aiProcess_FlipUVs); if(!scene || scene->mFlags & AI_SCENE_FLAGS_INCOMPLETE || !scene->mRootNode) { cout << "ERROR::ASSIMP::" << import.GetErrorString() << endl; } string directory = path.substr(0, path.find_last_of(‘/‘)); cout << directory << endl; // Get Root Node aiNode * node = scene->mRootNode; processNode(node,scene,"/"); return 0; } void processNode(aiNode * node, const aiScene* scene,string pwd){ cout << ">>LOOP At Node:" << pwd <<" WORLD MATRIX:" << endl; aiMatrix4x4 mat = node->mTransformation; cout << "{\n"; cout << "\t" <<mat.a1 << " " << mat.a2 << " " << mat.a3 << " " << mat.a4 << endl; cout << "\t" <<mat.b1 << " " << mat.b2 << " " << mat.b3 << " " << mat.b4 << endl; cout << "\t" <<mat.c1 << " " << mat.c2 << " " << mat.c3 << " " << mat.c4 << endl; cout << "\t" <<mat.d1 << " " << mat.d2 << " " << mat.d3 << " " << mat.d4 << endl; cout << "}\n"; for(unsigned int i = 0; i < node->mNumMeshes; i++) { aiMesh *mesh = scene->mMeshes[node->mMeshes[i]]; // mesh points cout <<">>Num points:" <<mesh->mNumVertices<< endl; // Dump materials infos aiMaterial *mat = scene->mMaterials[mesh->mMaterialIndex]; cout << ">>Get Mesh Name: "<<mesh->mName.C_Str()<< " <-> MaterialName: " << mat->GetName().C_Str() << endl; cout << ">>start dumping the texture:\n"; cout << "{\n"; for(unsigned int i = 0; i < mat->GetTextureCount(aiTextureType_DIFFUSE); i++) { aiString str; mat->GetTexture(aiTextureType_DIFFUSE, i, &str); cout << "\tdiffuseTexture: "<<str.C_Str() << endl; } for(unsigned int i = 0; i < mat->GetTextureCount(aiTextureType_NORMALS); i++) { aiString str; mat->GetTexture(aiTextureType_NORMALS, i, &str); cout << "\tNormalTexture: "<<str.C_Str() << endl; } for(unsigned int i = 0; i < mat->GetTextureCount(aiTextureType_AMBIENT); i++) { aiString str; mat->GetTexture(aiTextureType_AMBIENT, i, &str); cout << "\tAmbientTexture: "<<str.C_Str() << endl; } for(unsigned int i = 0; i < mat->GetTextureCount(aiTextureType_OPACITY); i++) { aiString str; mat->GetTexture(aiTextureType_OPACITY, i, &str); cout << "\tOpacityTexture: "<<str.C_Str() << endl; } for(unsigned int i = 0; i < mat->GetTextureCount(aiTextureType_SPECULAR); i++) { aiString str; mat->GetTexture(aiTextureType_SPECULAR, i, &str); cout << "\tSpecularTexture: "<<str.C_Str() << endl; } for(unsigned int i = 0; i < mat->GetTextureCount(aiTextureType_HEIGHT); i++) { aiString str; mat->GetTexture(aiTextureType_HEIGHT, i, &str); cout << "\tHeightTexture: "<<str.C_Str() << endl; } for(unsigned int i = 0; i < mat->GetTextureCount(aiTextureType_UNKNOWN); i++) { aiString str; mat->GetTexture(aiTextureType_HEIGHT, i, &str); cout << "\tUnkownTexture: "<<str.C_Str() << endl; } cout << "}\n"; } for(unsigned int i = 0; i < node->mNumChildren; i++) { string pathName = pwd + node->mChildren[i]->mName.C_Str(); pathName += "/"; processNode(node->mChildren[i], scene,pathName); } cout << "\n"; }
