I'm trying to write a vbo visualizer for raptor, but for some reason it crashes everytime I try to upload the texcoord's. The initial vertex buffer send works fine, so I'm not sure what could be causing it.
Here's the code. it crashes right after I log "Sending uv data". No error screen, just a blank screen for 20 seconds followed by an automatic power-down.
| Code: |
class VL_VertexBufferObject : public Visualizer
{
public:
virtual Visualizer * RequestNew()
{
return (Visualizer *) new VL_VertexBufferObject;
}
virtual void CreateResources()
{
Logger->Log("Creating VBO resources.\n");
glGenBuffersARB( 1, &_vbuf );
glGenBuffersARB( 1, &_tbuf );
glGenBuffersARB( 1, &_uvbuf );
Logger->Log("Created.\n");
}
virtual void SyncData()
{
Logger->Log("Syncing data.\n");
glBindBufferARB( GL_ARRAY_BUFFER_ARB, _vbuf );
Logger->Log("Sending data.\n");
glBufferDataARB( GL_ARRAY_BUFFER_ARB, _vertc*3*sizeof(float), (void *)_verts, GL_STATIC_DRAW_ARB );
Logger->Log("Sent.\n");
_mat->_texs.start();
int stage = 0;
while( _mat->_texs.next() == true )
{
if( stage == 0 )
{
Texture *tex = _mat->_texs.get();
Logger->Log("Binding uvbuf\n");
glBindBufferARB( GL_ARRAY_BUFFER_ARB,_uvbuf );
Logger->Log("Bound.\n");
Logger->Log("Sending uv data.\n");
glBufferDataARB( GL_ARRAY_BUFFER_ARB, _vertc*3*sizeof(float),(void *)_coords[tex->_coordset]->_uv, GL_STATIC_DRAW_ARB );
Logger->Log("Sent.\n");
}
stage++;
}
Logger->Log("Synced.\n");
}
virtual void Bind()
{
Logger->Log("Binding VBO\n");
glEnableClientState( GL_VERTEX_ARRAY );
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glBindBufferARB( GL_ARRAY_BUFFER_ARB, _vbuf );
glVertexPointer( 3,GL_FLOAT,0,(char *)NULL);
glBindBufferARB( GL_ARRAY_BUFFER_ARB, _vbuf );
glTexCoordPointer( 3,GL_FLOAT,0,(char *)NULL);
Logger->Log("Bound.\n");
}
virtual void Unbind()
{
Logger->Log("Unbinding.\n");
glDisableClientState( GL_VERTEX_ARRAY );
glDisableClientState(GL_TEXTURE_COORD_ARRAY);
Logger->Log("Unbound.\n");
}
virtual void Render()
{
Logger->Log("Rendering VBO \n");
glDrawElements(GL_TRIANGLES,_tric*3,GL_UNSIGNED_INT,_tris);
Logger->Log("Rendered.\n");
}
GLuint _vbuf;
GLuint _tbuf;
GLuint _uvbuf;
};

Here's the logger output.
