HELP! MutiTexturing in JME using GLSL

Troubleshooting General Help
1

When using MutiTexturing with GLSL,only the first texture can be accessed. The others cannot be visited. Why?



here is the code

import com.jme.app.BaseGame;
import com.jme.bounding.BoundingSphere;
import com.jme.image.Texture;
import com.jme.input.FirstPersonHandler;
import com.jme.input.InputHandler;
import com.jme.input.KeyBindingManager;
import com.jme.input.KeyInput;
import com.jme.light.PointLight;
import com.jme.math.FastMath;
import com.jme.math.Quaternion;
import com.jme.math.Vector3f;
import com.jme.renderer.Camera;
import com.jme.renderer.ColorRGBA;
import com.jme.scene.Node;
import com.jme.scene.Spatial;
import com.jme.scene.shape.Sphere;
import com.jme.scene.state.GLSLShaderObjectsState;
import com.jme.scene.state.LightState;
import com.jme.scene.state.TextureState;
import com.jme.scene.state.ZBufferState;
import com.jme.system.DisplaySystem;
import com.jme.system.JmeException;

import com.jme.util.Timer;

public class TextureMapping extends BaseGame
{
   private Node rootNode;
   protected Timer timer;
   private Camera cam;
   protected InputHandler input;
   
   private int width, height, depth, freq;
   private boolean fullscreen;
   
   private Sphere sphere = new Sphere("sphere1",150,150,10);
   private float angle = 0;
   Quaternion quad=new Quaternion();
   Quaternion rotQuat=new Quaternion();
   
   @Override

      // TODO Auto-generated method stub
      timer.update();
      interpolation = timer.getTimePerFrame();   
      input.update(interpolation);
      // if escape was pressed, we exit
      if (KeyBindingManager.getKeyBindingManager().isValidCommand("exit"))
      {
         finished = true;
      }
      if (interpolation < 1)
      {
         angle = angle + (interpolation * 0.5f);
         if (angle > 360)
         {
            angle = 0;
         }
      }
      
      quad.fromAngleAxis(-FastMath.PI/2,new Vector3f(1,0,0));

      sphere.setLocalRotation(rotQuat);
   }

   @Override
   protected void render(float interpolation)
   {
      // TODO Auto-generated method stub
      display.getRenderer().clearBuffers();
      display.getRenderer().draw(rootNode);
   }

   @Override
   protected void initSystem()
   {
      // TODO Auto-generated method stub
      width = properties.getWidth();
      height = properties.getHeight();
      depth = properties.getDepth();
      freq = properties.getFreq();
      fullscreen = properties.getFullscreen();
      
      try
      {
         display = DisplaySystem.getDisplaySystem(properties.getRenderer());
         display.createWindow(width, height, depth, freq, fullscreen);

         cam = display.getRenderer().createCamera(width, height);
      }
      catch (JmeException e)
      {
         e.printStackTrace();
         System.exit(1);
      }

      //set the background to black
      display.getRenderer().setBackgroundColor(ColorRGBA.black);
      
      //initialize the camera
      cam.setFrustumPerspective(45.0f, (float)width / (float)height, 1, 1000);
      Vector3f loc = new Vector3f(0.0f, 0.0f, 35.0f);
      Vector3f left = new Vector3f(-1.0f, 0.0f, 0.0f);
      Vector3f up = new Vector3f(0.0f, 1.0f, 0.0f);
      Vector3f dir = new Vector3f(0.0f, 0f, -1.0f);
      // Move our camera to a correct place and orientation.
      cam.setFrame(loc, left, up, dir);
      /** Signal that we've changed our camera's location/frustum. */
      cam.update();
      
      /** Create a input controller. */

you have to set the texture unit number for the samplers. like setUniform( "Monkey", 0 ), setUniform( "Dirt", 1 ) etc

look at the bloomrenderpass source on how it's done…

thanks very much.it works well when i add

   so.setUniform("Monkey", 0);

       so.setUniform("Dirt",1);

.



and another question. if i have a "uniform sampler3D Noise" in fragment shader. How to setup it in the application. Did JME support 3DTexture?

4

and how to setup samples like sampler2DShadow,sampler2DShadow and samplerCube??  :smiley:
