Height Map

a height map is a digital representation of the surface of a 3d object a height map is a two dimensional image that stores the height of the terrain at each pixel height maps are used to create 3d terrain in video games and other applications they can also be used to create other 3d objects, such as mountains, valleys, and cliffs here are some of the benefits of using height maps in 3d graphics efficient height maps are a very efficient way to represent 3d terrain this is because they only store the height information at each pixel, and they do not store the information about the shape of the terrain scalable height maps can be scaled up or down without losing any detail this makes them ideal for creating large scale 3d terrains easy to use height maps are relatively easy to use this is because they can be imported into most 3d modeling software here are some of the drawbacks of using height maps in 3d graphics not as realistic height maps can produce unrealistic results, such as jagged edges and flat surfaces not as versatile height maps can only be used to create terrain that is made up of a series of flat planes limited detail height maps can only store a limited amount of detail this means that they cannot be used to create very detailed 3d terrain overall, height maps are a versatile and efficient way to represent 3d terrain in 3d graphics however, they can produce unrealistic results and are limited in the amount of detail they can store here are some additional tips for using height maps in 3d graphics use a high resolution height map using a high resolution height map will help to reduce the jagged edges and flat surfaces that can occur with low resolution height maps use a displacement map a displacement map is a type of texture map that can be used to add more detail to a height map a displacement map is essentially a height map that is stored as a texture when the texture is applied to a 3d object, the height of the object is modified to match the height of the displacement map use a normal map a normal map is a type of texture map that can be used to add more realism to a height map a normal map is a texture map that stores the normal vectors of the 3d object the normal vector is a vector that points in the direction of the surface normal at each pixel when a normal map is applied to a 3d object, the lighting on the object is modified to make it look more realistic feedback please be sure to submit issues or feature requests through the embedded feedback form in the event it is a major issue please contact us directly through discord
