bump tech

Bump mapping is very much like Texture mapping. However, where Texture Mapping added colour to a polygon, Bump Mapping adds, what appears to is surface roughness. This can has a dramatic effect on the look of a polygonal object. Bump Mapping can add minute detail to an object which would otherwise require a large number of polygons. Note that the polygon was stil

1. The following is a simple introduction to what is called bump Mapping.Bump mapping is also called bump mapping, in the current graphics processing and games are very popular (we should have played Halflife-2 or doom it? ）。 The biggest difference between a bump map and a normal map is that each pixel in the bump map

Bump mapping is a illumination technique used to disturb the surface vector of an object at the pixel level. It simulates the object's "bumps" by changing the light calculation ". A paper first published by Jim BlinN named "simulation of wrinkled surfaces" by bump mapping. blinN uses a grayscale height map to simulate the disturbance of the surface normal vector of an object. so what is

So how do you simulate this effect in 3D graphics? Is the modeling method used to build a rough surface for the surface of the model? This method is difficult to make real

The purpose of this tutorial is to help those who are interested in graphic rendering technology but suffer from finding free Chinese learning materials. None of my colleagues engaged in computer science have learned the basic operations of WINDOWS, and my computer technology has been completely self-taught step by step, the programming history of computing has been nearly five years. I often spend more than half of my learning time querying learning materials (I remember that it took nearly two

And promises to tell you about the important tools in 3D geometry, tangent space, in the background. Today, we are here to tell you about the next part of the work.Tangent SpaceAs we know, in the previous article, the normals in the described normal map are i

In order to calculate the I, J point's normal, we can first calculate the S, T direction Tangent Vector Based on the height difference:S (I, j) = T (I, j) = A is a scaling factor. Normal can be obtained from the two tangent vectors.N (I, j) = normalize (Cross (S, T) = cross (S, T)/length (Cross (S, T) = You can then sto
