The standard way to calculate mvp matrix is:
P*V*M * v1 = v2
In rendering my entity list, I would like to do something like the following:
(for those not involved in games, an "entity" is a "unit" in the game world, such as an enemy or ally, the mapping typically being one entity to one (animated) mesh)
Code :update() create camera matrix create view matrix as inverse of camera matrix precalculate combined pv matrix for each entity m * pv //as opposed to m * p * v if no precalc of pv make draw call
...Since this would result in one less matrix mul() per-entity, per-update -- leading to a fair saving when there are hundreds of entities active. Just not sure this is possible (mathematically) since then the matrix multiplication order p * v * m is duffed. Is there a way to do this, mathematically?
