Problem with: glutSolidSphere & GL_QUADS

[Bananni]

Hi,
for my battle system im using a Cubemap to fake a full 3D world.
Im using 6 textures, 4 for sides and 2 for ground and sky.
Now i would like to use GL_QUADS to display my 2D battlers.
The problem now is: My Battlers arent display =/
Heres the code/setting im using:
settings:

1   2   3   4   5   6   7   8   9   10   11   12   13   14

gl.glClearColor(0.0f, 0.0f, 0.0f, 0.5f);         gl.glShadeModel(GL.GL_FLAT);         gl.glEnable(GL.GL_TEXTURE_2D);         gl.glEnable(GL.GL_BLEND);         gl.glColorMask(true, true, true, true);         double widht = 774;         double height = 540;         final float h = (float) width / (float) height;         gl.glMatrixMode(GL.GL_PROJECTION);         gl.glLoadIdentity();         glu.gluPerspective(60.0f, h, .1, 10);         gl.glViewport(0, 0, (int)width, (int)height);         gl.glMatrixMode(GL.GL_MODELVIEW);         gl.glLoadIdentity();

render:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36   37   38   39   40   41   42   43   44   45   46   47   48   49

public void render(GL gl){     renderBG(gl);     for(int i=0;i<battler.length;i++){ // 2 Battlers       Texture tex = battler[i].battler.animations[battler[i].action].getFrame(); // The Texture is a texture with content.       tex.bind();       tex.enable();       gl.glTranslatef(battler[i].coor.xf, battler[i].coor.yf, battler[i].coor.zf); // All Coor are zero.       TextureCoords coords = tex.getImageTexCoords();       gl.glBegin(GL.GL_QUADS);         gl.glTexCoord2f(coords.left(), coords.bottom());         gl.glVertex3f(0, 0, 0);         gl.glTexCoord2f(coords.right(), coords.bottom());         gl.glVertex3f(1, 0, 0);         gl.glTexCoord2f(coords.right(), coords.top());         gl.glVertex3f(1, 1, 0);         gl.glTexCoord2f(coords.left(), coords.top());         gl.glVertex3f(0, 1, 0);       gl.glEnd();       gl.glTranslatef(-battler[i].coor.xf, -battler[i].coor.yf, -battler[i].coor.zf);     }   }   private void useCamera(GL gl){     gl.glRotatef((float)Math.toDegrees(Camera.v),1f,0f,0f); // is zero.     gl.glRotatef((float)Math.toDegrees(Camera.h),0f,1f,0f); // is zero.     gl.glRotatef((float)Math.toDegrees(Camera.c),0f,0f,1f); // is zero.   }   private void renderBG(GL gl){     cubemap.bind();     cubemap.enable();     gl.glEnable(GL.GL_LIGHTING);     gl.glTexGeni(GL.GL_S, GL.GL_TEXTURE_GEN_MODE, GL.GL_NORMAL_MAP);     gl.glTexGeni(GL.GL_T, GL.GL_TEXTURE_GEN_MODE, GL.GL_NORMAL_MAP);     gl.glTexGeni(GL.GL_R, GL.GL_TEXTURE_GEN_MODE, GL.GL_NORMAL_MAP);     gl.glEnable(GL.GL_TEXTURE_GEN_S);     gl.glEnable(GL.GL_TEXTURE_GEN_T);     gl.glEnable(GL.GL_TEXTURE_GEN_R);     gl.glTexEnvi(GL.GL_TEXTURE_ENV, GL.GL_TEXTURE_ENV_MODE, GL.GL_REPLACE);     gl.glMatrixMode(GL.GL_TEXTURE);     gl.glPushMatrix();     gl.glLoadIdentity();     useCamera(gl);     glut.glutSolidSphere(5.0, 40, 20);     gl.glDisable(GL.GL_LIGHTING);     gl.glPopMatrix();     gl.glMatrixMode(GL.GL_MODELVIEW);     gl.glDisable(GL.GL_TEXTURE_GEN_S);     gl.glDisable(GL.GL_TEXTURE_GEN_T);     gl.glDisable(GL.GL_TEXTURE_GEN_R);   }

Hi!

Have you ever succeeded in displaying your fighters before using quads?

[Bananni]

Yes, in ortho mode they was displayed, before in 3D Mode also, but now its not possible anymore and i dont get it why i cant display them anymore =/
OK! now my system is displaying the Quad, i made a mistake with Z, i used + instead of - and i forgot to use: cubemap.disable();
Thx, can be closed

Please can you post the both pieces of code with your corrections? It would allow me to see exactly what you did to make it work.

The upper part i didnt change.
I juz realized that i used .1 to 10 for range.
So i changed the Z Coor of my Battler to -6f and there he was :3
In the next step i saw that my battler has a polygon, but no texture.
I searched for the reason and i saw the line: cubemap.enable();
so i completet it @ the end of my background rendering by: cubemap.disable();
Here are my modifications:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36   37   38

private void renderBG(GL gl){     gl.glLoadIdentity();     cubemap.bind();     // -------------------------------------- WHERES THE REST? :(    cubemap.enable();     // -------------------------------------------------------------------    gl.glEnable(GL.GL_LIGHTING);     gl.glTexGeni(GL.GL_S, GL.GL_TEXTURE_GEN_MODE, GL.GL_NORMAL_MAP);     gl.glTexGeni(GL.GL_T, GL.GL_TEXTURE_GEN_MODE, GL.GL_NORMAL_MAP);     gl.glTexGeni(GL.GL_R, GL.GL_TEXTURE_GEN_MODE, GL.GL_NORMAL_MAP);     gl.glEnable(GL.GL_TEXTURE_GEN_S);     gl.glEnable(GL.GL_TEXTURE_GEN_T);     gl.glEnable(GL.GL_TEXTURE_GEN_R);     gl.glTexEnvi(GL.GL_TEXTURE_ENV, GL.GL_TEXTURE_ENV_MODE, GL.GL_REPLACE);     gl.glMatrixMode(GL.GL_TEXTURE);     gl.glPushMatrix();     gl.glLoadIdentity();     useCamera(gl);     glut.glutSolidSphere(5.0, 40, 20);     gl.glDisable(GL.GL_LIGHTING);     gl.glPopMatrix();     gl.glMatrixMode(GL.GL_MODELVIEW);     gl.glDisable(GL.GL_TEXTURE_GEN_S);     gl.glDisable(GL.GL_TEXTURE_GEN_T);     gl.glDisable(GL.GL_TEXTURE_GEN_R);     // ------------------------------------------------- HERE IT IS :3    cubemap.disable();     // -------------------------------------------------------------------  }
