[solved] [batching] How to transform drawing primitives

OpenGL Development
#1

So I have a problem, In my eyes, doing this:

someBatch.begin();
someBatch.add(10, 10, 10, myMesh);
someBatch.end();

Is super super bad… I’d prefer if it was

someBatch.begin();
someBatch.add(myMesh);
someBatch.end();

And used a matrix inside the mesh to change it’s positions/texcoords like so:

public class MeshBatch ...

public void add(Mesh mesh){
       for(Vertex v : mesh.getVertices){
             v.position = v.position.mul(mesh.vertTransform);
             v.texUV    = v.texCoord.mul(mesh.texTransform);
       }
       //... Add values to buffer
}

...

Would doing the above operation be bad on the CPU? Is there another possible way (if so, please explain)?

Thanks in advance!
