So I'm writing a parser for wavefront obj model files and there are a few irregularities that I'm not sure how to handle. So based off of my reading, a mesh can be broken up into groups using the...

How does one export a 3D Studio animated model to OBJ format (if possible)? What will be the resulting file like? How would I read that?

I was building a little 3D-application using ThreeJS and WebGL. I purposely chose not to convert models into ThreeJS compatible .json files, instead started building an importer. It works, but I al...

I am working on a .obj handler in c++. Importing the data shouldn't be a Problem, but i do not understand why it is possible, that a .obj (e.g. exported from blender) has more 'vt' entries than 'v'...

I'm developing an application with React VR and I've created an 3D pokeball with blender. I've export this as Wavefront .obj file and use it in my React VR application. In the console I see this w...

At first, it seemed obvious... Make 2 triangles per face wherever 4 indices were found, right? Meaning, the following: v 1.000000 1.000000 0.000000 v -1.000000 1.000000 -0.000000 v 1.000000 -1.000...

I have a .mtl file next to my .obj file which specifies the materials for the object. Im trying to create a parser but dont know what the "Ke" attribute means. e.g: Ka 0.78 0.78 0.78 Kd 0.78 0.78...

I've imported a Wavefront OBJ file from a URL and now I'd like to insert it into my scene (SceneKit) on my iOS 9 app (in Swift). What I've done so far is: let asset = MDLAsset(URL: localFileUrl) p...

I'm coding my own .obj parser in objc for OpenGL ES 2.0 to get a better understanding on how this OpenGLES thing works. Loading the vertices and showing a model with vertex colors on it works like ...

While trying to a parse a wavefront .obj file, I thought of two approaches: Create an 2D array the size of the number of vertices. When a face uses a vertex, get it's coordinates from the array. ...

I want to know how can I use the vertex normals for lightning effect? Currently what I have is I can send both vertex and texture coords to the shader and use them but with normals, I don't know ho...

I am creating an OBJ parser which reads the file and draw it using glDrawElements. The thing here is the model is correctly drawn but when I try to give it a texture, it is incorrectly mapped. I ha...

I have this kind of matrix (13 x 13): 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 0 0 ...

I am trying to load .obj files into an Android project with LibGDX. The files have no texture file, but include materials in .mtl files. I'm using the latest official nightly, and rendering the obj...

So using a Wavefront object file how am i supposed to render faces that have more than 4 vertices in OpenGL? I understand that if it has 3 vertices I use GL_TRIANGLES, if it has 4 I use GL_QUADS, ...

I want to recursively parse a string and store the results in one struct. I've written a parser that can handle one iteration. The input is formatted as follows: v 1.5 2.0 2.5 v 3.0 3.5 4.0 f 1 2 ...

I want to write a parser for Blender's .obj file. The file format seems self explanatory, but also it seems to be missing some data. For example, a simple cube (the default Blender cube) has 8 line...

I'm writing an android app using openGL ES. I followed some online tutorials and managed to load up a textured cube using hard-coded vertices/indices/texture coordinates As a next step I wrote a p...

Back with my daily silly question. Today I'm trying to put a struct in an NSArray. Alright, that's easy, wrap it in a NSData. If you know me, you know you're about to see code. In this example, I'm...
