Hello guys.

I came across a problem today. I exported a single cube from blender, and I tried to wrote a simple .obj loader to use. I think my parsing method is okay, but I have problem putting the data into a vbo/ibo. The vertex and fragment shader is working, I used them before. What I get is a deformated cube. Like faces (quad) only got one of the tris drawn.

Vertex class contains fields for position, texcoords, and normals

FaceData just holds the ID for vertex, texcoord and normal.


public class Model {

    ArrayList<Vertex> vertices = new ArrayList<Vertex>();
    ArrayList<Vector3f> pos = new ArrayList<Vector3f>();
    ArrayList<Vector2f> tex = new ArrayList<Vector2f>();
    ArrayList<Vector3f> norm = new ArrayList<Vector3f>();
    ArrayList<FaceData> faces = new ArrayList<FaceData>();

    int vbo;
    int ibo;

    public int indexCount;

    public Model(String name)
    {
        parseObj(name);

        FloatBuffer vertBuffer = BufferUtils.createFloatBuffer(vertices.size() * 8);

        for(Vertex v : vertices)
        {
            vertBuffer.put(v.getElements());
        }

        vertBuffer.flip();

        vbo = GL15.glGenBuffers();
        GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, vbo);
        GL15.glBufferData(GL15.GL_ARRAY_BUFFER, vertBuffer, GL15.GL_STATIC_DRAW);
        GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, 0);

        IntBuffer indices = BufferUtils.createIntBuffer(faces.size());

        for(FaceData f : faces)
        {
            indices.put(f.vertexID - 1);
            indexCount++;
        }

        indices.flip();

        ibo = GL15.glGenBuffers();
        GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, ibo);
        GL15.glBufferData(GL15.GL_ELEMENT_ARRAY_BUFFER, indices, GL15.GL_STATIC_DRAW);
        GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, 0);
    }

    public void render()
    {
        GL11.glBindTexture(GL11.GL_TEXTURE_2D, 0);

        GL20.glEnableVertexAttribArray(0);
        GL20.glEnableVertexAttribArray(1);
        GL20.glEnableVertexAttribArray(2);

        GL20.glVertexAttribPointer(1, 2, GL11.GL_FLOAT, false, 32, 12);
        GL20.glVertexAttribPointer(2, 3, GL11.GL_FLOAT, false, 32, 20);
        GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, ibo);
        GL11.glDrawElements(GL11.GL_TRIANGLES, indexCount, GL11.GL_UNSIGNED_INT, 0);
        GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, 0);

        GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, 0);

        GL20.glDisableVertexAttribArray(0);
        GL20.glDisableVertexAttribArray(1);

int texcount = -1;

	   for (i = 0; i < k->Count; i++)
		if (Pos("vt",LowerCase(k->Strings[i])) > 0) {
	   s = k->Strings[i];
get_all_in_nawias(s, " ",4);
				 texcount = texcount + 1;
VBO_T[texcount].x = pstrtofloat(w_nawiasie[4][1]);
VBO_T[texcount].y = pstrtofloat(w_nawiasie[4][2]);



	   }

delete k;

SaveModel(result+"PYK2.tachogl",false);
SaveToBGLCMD(result+"PYK_BGLCMD.TXT",false);
}

this is the present code now it uses one librarty that i have written long time ago in object pascal but i have it on my broken notebook, and i dont have time to show you this unit:

one thing is that

get_all_in_nawias(s, " ",4); is a function that separates string into an array (the splitter is in this case " ")

but i looked into this more modern code and found some steps you want to make:

count vertices and faces, then you gather face info and match corresponding vertices to it, its all there

First of all, just to make sure: remember that indices in OBJ models start counting from 1, not from 0. Yes, this catches off-guard pretty much everybody who attempts to make an OBJ parser. I didn't take a close look at the code so I may have missed something but it didn't seem like you were accounting for that.

EDIT: nevermind it seems like you handle that at the end, unless I misunderstood something.

Don't pay much attention to "the hedgehog" in my nick, it's just because "Sik" was already taken =/ By the way, Sik is pronounced like seek, not like sick.

I replaced drawElement with drawArrays, and it draws the cube perfectly, so the problem is with the indices.
