Tangent spaces (Tangent space) normal mapping (normal Mapping)

// Please specify the source: Http://blog.csdn.net/BonChoix, thank you ~) Tangent spaces (Tangent space) Switching space, same as local space, world space, is one of the many coordinate systems in 3D graphics. One of the most important uses for

When normalmap is exported from 3dsmax, the "correct" Algorithm of the tangent vector

Currently, many tools can directly generate normalmap. Algorithm Different algorithms make the calculation of tangent and binormal a little different. Currently, most artists use 3 DSMAX most often. Using Max to generate normalmap is also a common

Reverse Engineering (RE) Reverse Modeling Technology

Geometric modeling technology has been widely used in product development and manufacturing. However, for various reasons, there are still many products that are not described by the CAD model, and the design and manufacturer are facing the physical

Computing Tangent in Ogre is very good!

Code Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Vector3 Math: calculateTangentSpaceVector ( Const Vector3 & position1, const Vector3 & position2, const Vector3 & position3, Real u1, Real v1,

Calculate the tangent space

Tangent space: Because the video card is generally used as the smallest rendering unit, we assume that the three points of the triangle are P1, P2, and P3, and set the space corresponding to the triangle to (T, B, n ), where T and B constitute the

"Unity Shader" uses the Shader of the normal map (normal map)

Why use normal mapsIn order to improve the model performance details without increasing the performance consumption, it is not a choice to increase the number of faces of the model, but rather to use the upper normal map (normal map) for the model's

A programmer's neural network reverse communication

It can be considered that artificial neural network is a meta function, it can receive a fixed number of digital input and generate a fixed number of digital output. In most cases, the neural network has a layer of hidden neurons in which the hidden

Algorithm analysis of baseline turn protection Area

Everyone is good, I am striving for the wind spiral written into the norms of the Liu Chongjun, I wish you all the year of the dog boom, thinking things into!What I want to share with you today is the method of calculating the baseline turn

[]html5 Canvas Drawing Tutorial (6) method of ArcTo in-canvas curve

Arc and ArcTo are similar from name to title. ArcTo is also a way of drawing curves, and the curves he draws are also arcs of a circle. But his parameters and arc are absolutely mortal.Ctx.arcto (X1,y1,x2,y2,radius), ArcTo's parameters include two
