Bump Maps in Photoshop 3D
Bump maps are grayscale images that allow you to kém chất lượng detail in 3d objects. The detail that they generate is simply a lighting trick on the surface of 3d objects. The actual 3d geometry is not changed in any way.
The 256 different levels of luminosity inbump maps are used to lớn tell the Photoshop how far to push down or pull down.
Bump maps are really easy lớn create using Photoshop’s 3 chiều filters. Go to Filter > 3 chiều > Generate Bump Map. This will bring up the Generate Bump maps dialog box which gives you an interactive 3d preview, with controls on how to generate the grayscale image that will 3d your Bump map.
After you generate your Bump map, you can edit it with any of photoshop’s regular adjustments, tools, or filters. One common technique is to lớn use the Dodge và Burn tools to lớn adjust the luminosityof certain areas.
Even thoughBump Maps can be very useful in many projects, their drawback is that in certain angles they vì chưng not look very realistic.
Normal Maps in Photoshop 3D
Normal Maps are very similar khổng lồ bump maps. They also allow you to giả the illusion of depth and detail on a 3 chiều object without actually adding any 3 chiều geometry. But Normal maps bởi it in a different way.
A normal bản đồ uses RGB information that corresponds lớn the X, Y và Z axis in 3d space. The RGB channels tell Photoshop the direction of the surface normals are oriented in for each & every polygon.
Normal maps are as easy khổng lồ create in Photoshop as Bump maps. Go khổng lồ Filter > 3 chiều > Generate Bump Map.
The Generate Normal maps dialog box is almost identical lớn the Generate Bump bản đồ dialog box. It also gives you an interactive 3 chiều preview, with controls on how to generate the image that will make up your Normal map.
Unlike a Bump map, Normal maps can be very difficult edit in Photoshop. Each RGB channel is adjusted lớn present a movement in a single axis in 3D. This means thatany adjustments would need to be made the appropriateRGB channel, & not the whole image.
Depth Maps in Photoshop 3D
Depth maps are 2d images that use their luminance values khổng lồ create 3d objects. Unlike Bump maps or Normal maps, Depth maps in Photoshop bởi vì alter the 3 chiều geometry of an object.
In this tutorial, we use a Bump map as a Depth bản đồ to create our 3d object.
This image was also created using a Depth maps 3D modeling technique similar khổng lồ the one shown in this video.

Reply Constance Reber 4 years ago Hi J,
I did enjoy this lesson and spent a lot of time on it, as this is new information for me. I will split my lesson nhận xét sessions into smaller chunks for now though since, lượt thích an old tệp tin cabinet, too much new front load causes random files khổng lồ fall out the back!
I did have significant difficulty following without frequent rewinds as the control panels are small và blurry, especially following along with a split screen (I use windows và have a large desktop monitor).
I would vày much better with a separate window on your screen that shows the editing selections as (or more) prominent than the sản phẩm results. I have the latest versions of Adobe & a strong machine, but my control options vary from yours at times, which is another reason why clear directions are imperative for those of us who are unfamiliar with 3d controls on PS. Sidebar: my tools are set to default & yet my selection marque only offers a 2 chiều vertical or horizontal line without any scrolling rectangles (used to lớn select render area). So, I just used the lasso (which looks different from yours too).
In this lesson, I really liked that there is not any background noise & that your voice is easy lớn understand.
