This value can also be negative, in which case the displacement pushes geometry inside the object. Higher values produce a greater displacement effect. A value of 0.0 means the object appears unchanged. You cannot use this method for 3D procedural textures or other textures that use object or world coordinates.Īmount – Specifies the amount of displacement. However, it requires that the object has valid UV coordinates. The advantage of this method is that it preserves all the details in the displacement map. The actual raytracing of the displaced surface is done in texture space, and the result is mapped back into 3D space. The displaced surface is rendered as a warped height-field based on that texture map. 2D Displacement – Bases the displacement on a texture map that is known in advance. Normal Displacement – Takes the original surface geometry and subdivides its triangles into smaller sub-triangles which are then displaced. Let me know if you have any questions.Mode/Map – Specifies the mode in which the displacement is rendered:
The process should be about the same in Kerkythea or Vray for Sketchup but I haven’t looked at it so I can’t be sure. I have also applied a transparency map in the above render because you can use maps singularly or layer them together to get the desired effect.īecause the displacement map is generating geometry, its profile is quite different from the bump map’s.
So, instead of appearing to have depth, displacment maps actually give the texture depth.īut because they are creating geometry displacement maps are also the most computer intensive and take the longest to render.Īs you can see the displacement map brings the texture to life and interacts with the scene’s light source. Displacement maps are the third and most powerful of the common maps.ĭisplacement maps can use the same black and white image that was developed for the bump map but instead of shifting the image while it stays flat, the Displacement map actually generates geometry by using the map as a heightfield where white is the most displacement and black is the least.
