In order for erosion to occur three processes must take place: detachment, entrainment and transport. Erosion also requires a medium to move material. Wind, water, and ice are the mediums primarily responsible for erosion.

What is it used for today? Lithography is a printing medium using a stone press on which areas are made receptive to ink, while other areas are not. The word “litho” means stone, which relates to the use of the stone press. Today, lithography is mainly used in modern-pop art and in printmaking.

If the subject is carved into the wall – or is sculpted so it stands out – it is called a low relief image – it is partly 3-dimensional on the surface of the wall. A ‘frieze’ can likewise be in ‘releif’; in which case you’d be looking at a kind of 3-dimensional border – or it can simply lie flat against the surface.

The maps proceed from the general to the more specific. It is called a “relief-like” map, since it uses various colors and shading to shows areas of different elevation, and some shadowing to highlight steep slopes.

Contour lines are an effective device for representing relief on topographic maps. They can be defined as an imaginary line connecting points of equal elevation on the ground surface.

a relief map shows the difference between elevations in an area, and a physical map shows the natural features of the Earth. C.a relief map shows the natural features of the Earth, and a physical map shows human-created features such as boundaries.

In geography, a location’s relief is the difference between its highest and lowest elevations. A two-dimensional relief map displays the topography of a given area. Physical relief maps actually have raised areas that represent different elevations. (You may have seen them in school.)2019年8月9日

You’ll never mistake them for a water feature: the symbol is a blue triangle with a dot in the middle. These symbols have nothing to do with getting wet. They’re what the OS map describes as “tourist and leisure information” – things like pubs and campsites and viewpoints.

Physical maps are designed to show the natural landscape features of Earth. They are best known for showing topography, either by colors or as shaded relief. Physical maps often have a green to brown to gray color scheme for showing the elevation of the land.

A raised-relief map or terrain model is a three-dimensional representation, usually of terrain, materialized as a physical artifact.

Raised relief maps are sometimes referred to as three-dimensional maps. …

Bump maps and normal maps are essentially the same thing. The primary difference is that normal maps have more information in them(because they use an rgb input) to give a more accurate bump effect. Bump maps use only a black to white map to understand the depth.

Bump maps are really easy to create using Photoshop’s 3D filters. Go to Filter > 3D > Generate Bump Map. This will bring up the Generate Bump Map dialog box which gives you an interactive 3D preview, with controls on how to generate the grayscale image that will make up your Bump map.

Create the Normal Map

1. Open texture in Photoshop as you would normally any image. Make sure the image mode is set to RGB.
2. Choose Filter → 3D → Generate Normal Map…
3. Adjust your map as necessary (I left my to default). Click OK.
4. Save your file as PNG (not sure if it really matters). You’re done!

In Node Editor Add two color textures (Image Texture nodes), set one as Color and the other as Non-Color Data. Connect the second one to the Height input of the Bump node (set the Strenght as you like). Plug it then to the Normal input of your Diffuse node.
