Body
I have encountered a problem trying to run a simple model loader/displayer based off some tutorials. Whenever I compile the following code, I get this error: <pre><code>Unhandled exception at 0x77ad15de in Test.exe: 0xC0000005: Access violation reading location 0x00000000. </code></pre> I know this means that a null pointer is being accessed which is illegal, but I cant seem to find one. Here is my code: <pre><code>gleMesh gleLoadMesh(const char* filename){ const aiScene* scene = aiImportFile(filename, aiProcessPreset_TargetRealtime_Fast); if(!scene){ fprintf(stderr,"[WARNING] Could not load file %s", filename); gleMesh load = {0,0,0,0}; return load; } const struct aiMesh* mesh = scene->mMeshes[0]; int tris = mesh->mNumFaces*3; float *verts = new float[mesh->mNumFaces*3*3]; float *normals = new float[mesh->mNumFaces*3*3]; float *uvs = new float[mesh->mNumFaces*3*3]; for(unsigned int i = 0; i < mesh->mNumFaces; i++){ const aiFace face = mesh->mFaces[i]; for(unsigned int j = 0; j < 3; j++){ aiVector3D vert = mesh->mVertices[face.mIndices[j]]; memcpy(verts, &vert, sizeof(float)*3); verts += 3; aiVector3D normal = mesh->mNormals[face.mIndices[j]]; memcpy(normals, &normal, sizeof(float)*3); normals += 3; aiVector3D uv = mesh->mTextureCoords[0][face.mIndices[j]]; memcpy(uvs, &uv, sizeof(float)*2); uvs += 2; } } gleMesh load = {0,0,0,0}; if(glv3){ glGenBuffers(1, &load.vertex); glBindBuffer(GL_ARRAY_BUFFER, load.vertex); glBufferData(GL_ARRAY_BUFFER, sizeof(verts), verts, GL_STATIC_DRAW); glGenBuffers(1, &load.normal); glBindBuffer(GL_ARRAY_BUFFER, load.normal); glBufferData(GL_ARRAY_BUFFER, sizeof(uvs), uvs, GL_STATIC_DRAW); glGenBuffers(1, &load.uv); glBindBuffer(GL_ARRAY_BUFFER, load.uv); glBufferData(GL_ARRAY_BUFFER, sizeof(uvs), uvs, GL_STATIC_DRAW); load.numTris = tris; } else{ load.vertex = glGenLists(1); glNewList(load.vertex, GL_COMPILE); int j = 0; for(unsigned int i = 0; i < mesh->mNumFaces; i++){ glNormal3f(normals[j], normals[j+1], normals[j+2]); glVertex3f(verts[j], verts[j+1], verts[j+2]); j+=3; } glEndList(); } verts -= mesh->mNumFaces*3*3; normals -= mesh->mNumFaces*3*3; uvs -= mesh->mNumFaces*3*2; aiReleaseImport(scene); return load; </code></pre> } I use this function here: <pre><code>int main(){ gleInit("Test", GLFW_WINDOW, SCREEN_WIDTH, SCREEN_HEIGHT); mesh1 = gleLoadMesh("resource/model/test.blend"); while(!glfwGetKey(GLFW_KEY_ESC) && glfwGetWindowParam(GLFW_OPENED)){ draw(); capFPS(); } gleQuit(); return 0; } </code></pre> The strangest part is, depending on what model format I choose to load, I will get an error break in a different place, but the error is always the same. I am using assimp version 3.0 and visual studio 2010.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
