How is the work with Assimp going?

Acutally I'm working on an something of an entity system right now, but it's mainly for the map editor

The models are rendered like they were before, but the code is cleaner now and I'm using Display Lists (26% Performance Increase) and Backface Culling (30% Performance Increase) faster but technique is nothing special. Also the old build of the OBJ Loader was really messy, didn't support rendering a mixture of quads/tris and wasn't very usable or fast.

I haven't done much with VBO's and what not, what do you mean by batch rendering??

for i = each model group
{
	currentModel=i;
	glBindTexture(..., currentModel->m_texture);
	glTexCoordPointer(...,...,..., currentModel->m_texCoords);
	glVertexPointer(..., ..., ..., currentModel->m_verticies);

	for l = each entity in model group
	{
		currentEntity=l;
		glPushMatrix();
			glTranslatef(currentEntity->x,currentEntity->y,currentEntity->z);glRotatef(currentEntity->r,currentEntity->rx,currentEntity->ry,currentEntity->rz);//etc.
		glPopMatrix();
	}
}

It's very motivating, and in a sort of "I want to learn everything and do it all myself" kind of way, this reminds me a very lot of Elysian Shadows. Keep rocking, friend.

zeid wrote: I hope that makes sense to you. Thats a very rough example of what I mean. Basically you are only setting up the model and texture to draw once, but then you are drawing the model multiple times in different places/with different properties.

GLuint _displayListId;

..

void MakeList()
    {
        // Set up a Display List for Drawing the Entity //
        _displayListId = glGenLists(1); // Make Room for the Display List //
        glNewList(_displayListId, GL_COMPILE); // Begin the Display List //
        DrawSomeShit(); // Add Commands for Drawing the Entity to the Display List //
        glEndList(); // End the Display List //
    }

void Draw(float x, float y, float z)
    {
        // Call the Display List for Drawing the Entity //
        glPushMatrix();
            glTranslatef(x, y, z);
            glCallList(_displayListId);
        glPopMatrix();
    }
