Hi forum,
i want to use order independent transparency (OIT) by using the "multiplicative blending" approach outlined in this article.
http://www.openglsuperbible.com/2013/08/20/is-order-independent-transparency-really-necessary/
Out of the box Babylon.js already supports the "sorting approach", by implementing the third rendering step documented here: (http://doc.babylonjs.com/tutorials/Transparency_and_How_Meshes_Are_Rendered).
But this will not work for overlapping meshes (which I need). In addition the multiplicative approach does not need the sorting step.
I believe, that "injecting" an additional step after rendering sorted alpha blended meshes and before rendering sprites would be a solution. My question are:
- Does this approach make sense in the Babylon world?
- And if so, how could I implement it without changing Babylon itself
