Hello!

I am trying to use OpenGLES to draw a x by y matrix of squares about an arbitrary point.

I have an array sideVertice[] that holds a series of vertex structs defined as such

typedef struct {
    GLfloat x;
    GLfloat y;
    GLfloat z;
} Vertex3D;

and an element array defined as such

GLubyte elementArray[];

my draw loop is as such

        glLoadIdentity();
        glVertexPointer(3, GL_FLOAT, 0, cube.sideVertice);

        for (int i=0; i<((cube.cubeSize + 1)*(cube.cubeSize + 1)); i++) {
            for (int j=0; j<=3; j++) {
                elementArray[j] = j + i*4;
                glDrawElements(GL_TRIANGLE_STRIP, 4, GL_UNSIGNED_BYTE, elementArray);
            }
        }
        for (int i=0; i<=3; i++)
            elementArray[i] = i;

However, the visual output is corrupted and I cannot figure out what the problem is.

here is an output of the vertice held in the array:

any ideas?
