LWJGL SlickUtil Texture Binding

Question

I am making a 3D game using LWJGL and I have a texture class with static variables so that I only need to load textures once, even if I need to use them more than once. I am using Slick Util for this. When I bind a texture it works fine, but then when I try to render something else after I have rendered the model with the texture, the texture is still being bound. How do I unbind the texture and set the rendermode to the one that was in use before any textures were bound? Some of my code is below. The problem I am having is the player texture is being used in the box drawn around the player after it the model has been rendered.

Model.java

public class Model {

public List<Vector3f> vertices = new ArrayList<Vector3f>();
public List<Vector3f> normals = new ArrayList<Vector3f>();
public ArrayList<Vector2f> textureCoords = new ArrayList<Vector2f>();
public List<Face> faces = new ArrayList<Face>();

public static Model TREE;
public static Model PLAYER;

public static void loadModels() {
    try {
        TREE = OBJLoader.loadModel(new File("assets/model/tree_pine_0.obj"));
        PLAYER = OBJLoader.loadModel(new File("assets/model/player.obj"));
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public void render(Vector3f position, Vector3f scale, Vector3f rotation, Texture texture, float shinyness) {
    glPushMatrix();
    {
        texture.bind();

        glColor3f(1, 1, 1);
        glTranslatef(position.x, position.y, position.z);
        glScalef(scale.x, scale.y, scale.z);
        glRotatef(rotation.x, 1, 0, 0);
        glRotatef(rotation.y, 0, 1, 0);
        glRotatef(rotation.z, 0, 0, 1);

        glMaterialf(GL_FRONT, GL_SHININESS, shinyness);

        glBegin(GL_TRIANGLES);
        {
            for (Face face : faces) {
                Vector2f t1 = textureCoords.get((int) face.textureCoords.x - 1);
                glTexCoord2f(t1.x, t1.y);
                Vector3f n1 = normals.get((int) face.normal.x - 1);
                glNormal3f(n1.x, n1.y, n1.z);
                Vector3f v1 = vertices.get((int) face.vertex.x - 1);
                glVertex3f(v1.x, v1.y, v1.z);

                Vector2f t2 = textureCoords.get((int) face.textureCoords.y - 1);
                glTexCoord2f(t2.x, t2.y);
                Vector3f n2 = normals.get((int) face.normal.y - 1);
                glNormal3f(n2.x, n2.y, n2.z);
                Vector3f v2 = vertices.get((int) face.vertex.y - 1);
                glVertex3f(v2.x, v2.y, v2.z);

                Vector2f t3 = textureCoords.get((int) face.textureCoords.z - 1);
                glTexCoord2f(t3.x, t3.y);
                Vector3f n3 = normals.get((int) face.normal.z - 1);
                glNormal3f(n3.x, n3.y, n3.z);
                Vector3f v3 = vertices.get((int) face.vertex.z - 1);
                glVertex3f(v3.x, v3.y, v3.z);
            }

Thanks for the help.

Answer 1

The quick way is enabling/disabling textures using glEnable(GL_TEXTURE_2D) / glDisable(GL_TEXTURE_2D). Whether it would be best to enable textures before rendering the player and then disabling them after or disabling them before the box and enabling them after, depends on the how/if the rest of your program uses textures throughout.
