Overall I think that doing more research into these maps has helped my understanding of these maps better, as before I only knew the brief information of the maps. Bump maps do not add geometry and the therefore keep low poly counts. Bump maps also manipulate the normals of an object to create the illusion of Bumps and Wrinkles. So unlike bump maps and normal maps, displacement maps can cause deformations to your model, therefore can do everything that changes in real geometry can do, such as casting shadows.īump Map A Bump map is a greyscale image, similar to a displacement map. These maps physically displace and effect the geometry of the mesh on which it is applied. A common use of this technique is to greatly enhance the appearance and details of a low poly model by generating a normal map from a high poly model or height map, this process is known as ‘Baking’.ĭisplacement Map Like a bump map, displacement maps are in grey-scale, in which store height information. It is used to add details without using more polygons. Then it will create a realistic fabric object such as sofa.
Its normal map can be applied to any graphical patterns (plain image) you want. By close examination, the micro-texture of the cloth can be seen. Normal Map Normal mapping is a technique used for faking the lighting of bumps and dents in a 3D Model. Fabric with Wrinkles and Creases(Fabric 0032) It is a plain fabric cloth, but it is very useful to texture cushions, pillows, bed sheets etc. So in this blog post I’m going to be talking about the different types of maps. In Today’s session we were taught the basics of different types of maps, mainly those that change the amount of detail in a Low Poly model.
