Java JOGL textured object not translating -

i have been attempting use jogl in standalone java app. have done work opengles on android , ported code android opengl java app. there have been syntax changes methods , build steps similar , in place.

i able draw vertex arrays of floats on canvas , pass color data shaders. working on texturing. problem is. able texture , apply additional colors shaders via java want able move object in 3d space.

without texturing, able rotate/translate object when apply texturing object (which apply texture), can not rotate/translate object.

if can point in right direction of overlooking. have searched , looked @ tutorials , examples seem doing basics of have.

to clarify, having issues moving textured object in 3d space.

this examplegl main renderer:

this texturehelper class:

public class texturehelper {  public static texture loadtexture(gl2 gl, glprofile glprofile, string filepath, string extension) {      try {             gl.glmatrixmode(gl2.gl_texture);             gl.glloadidentity();              inputstream stream = new fileinputstream(filepath);             texturedata data = textureio.newtexturedata(glprofile, stream, false, extension);             texture tex = textureio.newtexture(data);                          return tex;         }         catch (ioexception exc) {             exc.printstacktrace();             system.exit(1);         }     return null; }  } 

below vertex shader using when attempting apply texture:

uniform vec3 vertcolor;  attribute vec2 a_texcoord;  varying vec2 v_texcoord; varying vec3 col;   void main() {  gl_position=gl_modelviewprojectionmatrix*gl_vertex;  col=vertcolor;  v_texcoord = a_texcoord; } 

below fragment shader using when attempting apply texture:

precision mediump float;          uniform sampler2d s_texture; varying vec2 v_texcoord;  varying vec3 col;             void main()                          {                                // pass through color gl_fragcolor = vec4( col, 1.0 ) * texture2d(s_texture, v_texcoord);                                          } 

just woke morning , went right program starring @ it. realized may need set modelview matrix drawing before translation. worked!

this method missing , needed add before loading identitiy matrix. must have been set matrix.

gl.glmatrixmode(gl2.gl_modelview); 

honestly don't understand why works not but, when not textured, worked.

here simple change drawing method in main renderer:

@override public void display(glautodrawable drawable) {     // todo auto-generated method stub      gl2 gl = drawable.getgl().getgl2();      gl.glclear(gl2.gl_color_buffer_bit | gl2.gl_depth_buffer_bit);                   gl.glmatrixmode(gl2.gl_modelview);      gl.glloadidentity();      // call draw code here          gl.gltranslatef(0, 0, xloc);         gl.glrotatef(rotatex, 1, 0, 0);         gl.glrotatef(rotatey, 0, 1, 0);         gl.glrotatef(rotatez, 0, 0, 1);          square.draw(gl);       // end calls drawing   }
