Steps in Texture Mapping

  1. Set texture environment parameter (if not common for all texture, this has to be done later): 
     gl.glTexEnvf( .... );
  2. Read the texture into main memory (usually from a file) into a ByteBuffer. 
    


  3. 
Create texture object(s), one ID for each texture
we want in texture memory:

     gl.glGenTextures( ... );

    


  4. 
Specify a texture for an object
and load the texture from client memory (main memory)
into OpenGL's texture memory:

     gl.glBindTexture( ... );  // Set current texture.
 gl.glTexImage2D( ... );
 OR
 glu.gluBuild2DMipmaps(  ... )

    


  5. 
Set the textures' parameter:

     gl.glBindTexture( ... );  // Set current texture.
 gl.glTexParameteri( ... );

    


  6. 
Enable texture mapping:

     gl.glEnable( GL.GL_TEXTURE_2D );

    




  7. 
Indicate how the texture 
is to be applied to each pixel
Draw the scene, supplying both 
texture and geometric coordinates:

     gl.glBindTexture( ... );  // Set current texture.

	gl.glTexCoord2f( .. );
	gl.glVertex3f( .. );
	gl.glTexCoord2f( .. );
	gl.glVertex3f( .. );

    


  8. 
Delete texture from texture memory
(maybe disable textureing):

     gl.glDeleteTextures( ... );
 gl.glDisable( ... );
