![]() The bigger the steps required to walk down the length of added dimension the less performant it is. ![]() And the length of that dimension is determined by the distance of rasterization world position and parallax occlusion mapping world position. So you just add another dimension to every pixel rendering that mesh. With parallax occlusion mapping, you just take that world position and start walking forward (min and max step parameters allow you to define a range in space you can walk) unless you hit the height map. In the standard rendering of Unreal Engine 4, your mesh will be rasterized (rasterization is the process of drawing analytic shapes to screen utilizing linear transformations), this including tessellation, world position offset etc., and that rasterization output will be used as the world position, value of that pixel. But it can really bring your performance down depending on scene complexity, mesh complexity and screen resolution (talking about the current generation, as of 2017). Parallax Occlusion Mapping is a great technique for expressing more detail on sufficient hardware. ![]() Is this the next generation and better all around? Should i use POM as often as possible and eschew fine mesh details?īasically i'm asking, when is it good to use this feature, what's a good policy in applying it? Is it the best approach for doing this? Is it better than using a fairly complex mesh for all those little rocks? In terms of rendering time, and in terms of memory? How does this shift the load, and technical requirements on the client? This looks amazing, and works well as a tech demo. It's a relatively low poly hexagon with a POM Is it actually better, or more efficient, than doing the same thing with meshes?įor example, the rocky ground example from that scene: I can think of so many ways i could use this. I'm currently looking through the content examples project, and particularly the scene demonstrating parallax occlusion mapping.įrankly i'm blown away, this is amazing.
