From today onwards, we start translating Unity's official documents on shader. Translation level is more general, the purpose is mainly through translation to enhance the view of shader, but also make it easier for others to understand shader. The following starts the body content:WriteSurface ShadersShader that interact with light are very complex to write, with

Write in frontThanks to all the friends who came in to see. Yes, I'm currently going to write a book about unity shader.The purpose of the book is to have the following several: Summarize my experience with unity Shader and give others a reference. I am very aware of the difficulties of learning shader, and I have seen many questions raised by people in the group. I think learning

What is shaderA Shader (shader) is a program that operates on a 3D object and is executed by the GPU and is responsible for combining the input mesh (mesh) in a specified manner with the input map or color, and then outputting it. The drawing unit can draw the image onto the screen based on this output. The input map or color, plus the corresponding shader, as we

Shader is a piece of code that provides algorithms for specific processing stages in a rendering pipeline. The advent of shader is accompanied by a programmable rendering pipeline that enables game developers to control the rendering process and to have a greater creative space, so the emergence of shader can be seen as a revolution in real-time rendering techniq

has its own surface material, so, it can be said that the object's own property is "skeleton" + "surface material".It is because different objects have their own "skeleton" and "surface material", so that when we turn on the lights, we will see different objects.As we look at the world around us, we see many of the things that are present:1, the same scene, when the light is stronger, the object is also brighter, when the color of the light changes, we see the object surface color has also chan

Shader is very strange.CodeIts length is limited, its dynamic branch capabilities are weak, and its commands are expensive, which makes it difficult for you to use a single shader to handle all rendering requirements. there are so many different types of rendering requirements. If you want to write a specific piece of code for each rendering type, it will be very difficult, if we want to write a material sy

[Unity Shaders] explores the mechanism behind Surface Shader, shadersshader Reprinted please indicate the source: http://blog.csdn.net/candycat1992/article/details/39994049 Preface The mechanism behind Unity Surface Shader has always been a bit confusing for beginners. Unity Surface Shader is open to the public when it is in Unity 3.0. Its propaganda means als

Start with compute shader I like vertex/fragment shaders simple, they just do one thing (the vertex and color output to the screen), they do very well, but sometimes this simple limit you, when your CPU life cycle those matrices, Figure out and store on the map ...Compute Shader solves this problem, and I will explain its basics today, and I will tell you through an example of unity myself that using struct

　　Have always wanted to try to translate some of their own things, now found that translation is really not easy, if you directly to the author's original text in accordance with the English thinking translation, you will find Chinese reading is very awkward, but if you want to fully use the Chinese language way to translate, but also afraid of their understanding is not in place, Contrary to the author's willingness. So I think a lot of times, the domestic translator is helpless, the next time

For a long time did not insist on blogging blog, it is a moment to start a wave of post! Learning Unity for a while, about shader's book also read a few "Unity Shader primer", "Unity 3D shaderlab Development Combat Detail", open a series to record the learning notes. The principle is not much to say, a practical shader example is good.Looks like the beginning about shader's explanation are diffuse, however,

Shader, also known as shaders, is one of the more difficult points in unity.1:shader is a program for GPU execution, in Chinese called shaders;2: Shader is running on the graphics processing unit, can let the developer directly manipulate the graphics hardware rendering function;3:shader can develop a lot of good effec

Shader preparation for Cocos2dx engine 11-OpenGLES Rendering The underlying Graphics of Cocos2dx are drawn using OpenGL ES protocol. What is OpenGL ES? OpenGL ES (OpenGl for Embedded System) is a subset of OpenGL 3D graphics APIs. It is designed for Embedded devices such as mobile phones, PDAs, and game hosts. this API is defined and promoted by Khronos group. Khronos is a graphic software and hardware industry association, which focuses on open stand
