Problem using Batch.migrate with an IndexedVertexList #603

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Here is a simplified code which do nothing but in my app, using this leads to 
major problems on texture mapping (plus the error on ivl.delete())

import pyglet as pg
batch = pg.graphics.Batch()
ivl = batch.add_indexed(3,
                        pg.gl.GL_TRIANGLES,
                        None,
                        (0, 1, 2)
                        ('v2f', (0, 0, 0, 1, -1, 0)))
batch.migrate(ivl, pg.gl.GL_TRIANGLES, None, batch)    # This line is the 
problem
ivl.delete()

Error message on ivl.delete() :

So I just think Batch.migrate is not to be used with IndexedVertexList.

GoogleCodeExporter commented 9 years ago 
I am working on creating a 3d graphics engine and using the concepts behind 
sprite.Sprite and the graphics.py demo to create a 3d set of primitive objects 
(using pyglet 1.1.4 btw).  

Now to implement picking I want to be able to change the group the primitive 
belongs to.  Based on sprite.Sprite, changing groups basically calls 
self._batch.migrate(self._vertex_list, GL_QUADS, self._group, self._batch).  
Note that self._vertexlist in sprite.Sprite is not an indexed list (see 
Sprite._create_vertex_list).  When I try to do the same thing with an indexed 
vertexlist in my 3d engine I am getting some strange behavior. Looking at 
Batch.migrate in pyglet\graphics\__init__.py it seems that the 
batch._get_domain function is always called with False as the first argument, 
indicating that it's a regular vertexlist.  Therefore IndexedVertexList are not 
supported as issue 603 mentions.  

Taking a closer look at pyglet.graphics.vertexdomain revealed that 
IndexedVertexLists do not have .migrate method overloaded to account for the 
index buffer similar to .resize.  I took the concepts in VertexList.migrate and 
IndexedVertexList.resize and came up with the solution at the link provided 
below.  Here is the link to the repository and changes I made.

Let me know if this solves issue 603.

Version 1.1.4 is considered final, the development is happening in 1.2. I can 
only suggest you to try 1.2 from repository and see if that works for you 
(although it implies some API changes).
