I am attempting to render an ItemStack in 3D, hovering over a block.

I would like to use a FastTESR to do so.

I am using 

renderItem.getItemModelWithOverrides(stack, null, null);

to get the item model.

 

Problem is I would like to apply translation, rotation and scaling to the rendered model.
Is there a handy method I can use without touching all the baked quads myself?

(Also if there is better practice to do this I would greatly appreciate any advice)

 

Pointing me to some reference code or an example implementation should be enough.

Would it even be a good Idea to do those transformations every frame?
Using a FastTESR they would probably have to be computed on the CPU and using the matrix stack would be more efficient?

Thoughts?

 

If not are there common methods to apply transformations to the entirety of an IBakedModel?

I do not usually bump posts, but I have been digging through rendering classes for 2 days now and I cannot find something that is really helpful.
IBakedModel's are so finite.

I believe diesieben07 linked this code for a similar post about transforming baked quads.

Thanks that is exactly what I was looking for.
Yet the question remains if it is actually more efficient than using the matrix stack. Doing so many vertex operations on the cpu every frame does not feel correct.

Well I want to make the item rotate slowly, which requires an update every single frame.
