In many cases displacement maps are useful for creating mountains as well as things like surfaces of rivers beds with tons of stones and pebbles without having the need to add more geometry.
FILTER FORGE 6 VS 5 SOFTWARE
So if you want some protrusion and realistic surface detail, find a software that's capable of doing that. Depending on the software displacement maps may not exist. The displacement value does something a step above what the bump map does: it actually alters the geometry creating a much more detailed and further realistic look and feel to the object.ĭisplacement maps and bump maps can share the same black-and-white maps. So it's just a simulation of light passing over an object. So the basic idea of a bump map in a shader is to give the viewer a sense of depth by simulating the flow of light on a bumpy surface (given the grayscale map.) The unfortunate thing is that bump maps do not simulate actual depth in other words even if it LOOKS as though the object's surface has some form of bump, the geometry doesn't. When you apply light to these objects, the light will get picked up in certain areas leaving other areas in shadow. For example a surface of a rock is bumpy or a tree bark has a bumpy look. The bump value simulates lighting on a surface of a bumpy object. The reason why people get confused is because they all look like they do the same thing (excepting in the case between displacement and bump values, they're significantly different.) But each have significant differences between how they achieve a certain look or feel.įirst of all the bump value. The three things here have one goal: to make things look realistic and each have their way of doing it.
To add to the confusion there are software developers who like to switch between the two terms displacement and bump in their software so be careful. Unfortunately, bump, normal, and displacement maps tend to confuse people. It’s one of the more basic examples of what you can do with Filter Forge but their gallery page has some amazing examples of what other people have created by combining multiple filters.Alright, thought I'd make a nice big informational post regarding the three key things that make your shader look nice and detailed. Here’s an example of a filter that converts your photo into a watercolor painting. You still need to browse the website for the filters but the filters load automatically into Filter Forge when you click the open link.
FILTER FORGE 6 VS 5 DOWNLOAD
I didn’t like the idea of browsing a website to download filters because the first thing that comes to mind is the hassle of saving/loading the filters. Their website gives you access to 9000+ filters but most of them are very specific and there are many variations of similar effects. If you want the most filters in the world, Filter Forge will please you. You can generate seamless 2D/3D textures and apply photo effects. Filter forge is a Photoshop plug-in and standalone program with 9000+ filters and an editor to create your own filters. Photoshop has many built-in filters but if you need more, say 9000+ more, then you might be interested in Filter Forge.
