objpar | Single header Wavefront OBJ parser written in C | Graphics library

objpar is a C library typically used in User Interface, Graphics applications. objpar has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Single header Wavefront OBJ parser. Currently it depends on stdlib’s atoi and atof. You can provide your own implementation by doing. The current implementation defines two structures. The first one is struct objpar_data and the second one is struct objpar_mesh. The only function call needed to parse the OBJ string is objpar. The function objpar_build_mesh will generate a flat array containing the vertex data for the specified struct objpar_data structure. The vertex structure will depend on which parameters are stored on the parsed obj file. Here is how it would look for a file with position, normals and texture coordinates. The struct objpar_mesh structure will provide the data, vertex stride, vertex count, position, texcoord and normal offsets. With this information you can define your vertex input layout for different graphics API. If an offset has a value of -1 it means that it’s not part of the vertex.
