Use shader in cocos2dx (3.X)A shader's Basic Concept 1 What is a shaderThe shader is a painter that is used to render 3D images.With the shader, you can write your own graphics card rendering algorithm to make the screen more beautiful and realistic.2. shader ClassificationThere are two types of

Explanation of the Shader Series 9 Written by CG in Unity-mirror reflection and unityshader After the discussion, the next step will be the mirror reflection. Before starting the coding of the shader, you need to expand the previous knowledge to better understand the differences between the mirror reflection and the diffuse reflection. Note: The mirror reflection implemented in this article is colored by ve

Interpretation of the Shader Series 8 Written by CG in Unity-Multi-light source diffuse reflection and unityshader In the previous article, the simplest shader is only the diffuse reflection under a single light source, but often there is not only one light source in the scenario, so how can the diffuse reflection intensity of the surface of our objects be combined when multiple light sources exist? What do

This article is my study of Bull's set of shader tutorial (HTTP://WWW.UNITYTRAIN.CN/COURSE/96) After the simple summary, personal feeling this tutorial is not to advanced shader programming for the purpose, more like the purpose of giving people to fish. Below I will be divided into three parts: shader brief introduction, the basis of graphics, CG introduction fo

Label: style blog HTTP color Io OS ARAfter Apple launched metal, in addition to the new metal framewrok, it also had a new Shader Language. Recently, some metal porting tests were conducted, it is mainly about how the existing engine can quickly support metal solutions. I want to write my own experiences on edge Writing. The syntax of metal shader is closer to the HLSL of sm5. Therefore, the HLSL of sm4 or

In the previous article, the simplest shader is only the diffuse reflection under a single light source, but often there is not only one light source in the scenario, so how can the diffuse reflection intensity of the surface of our objects be combined when multiple light sources exist? What does the tag "lightmode" = "forwardbase" mentioned above mean? The built-in diffuseshader of unity, that is, when we create a material, the default

TimesCan save the provinceThree shader partsThis is a key point, we will find that the support Normals support the specular map, then we need a real-time light, otherwise after baking, the lights are off, shengThe most original diffuse effect + baking chart effect. For example: The left image is baked before the right picture is bakedOn the basis of baking, add a directional light, its normal effect with the high-gloss effect will come out. But add a

Following the summary of the shader introductory knowledge in the previous article, this paper summarizes the operation of texture mapping, transparency blending, vertex animation and post effect processing in shader. If there is something wrong, please point out the correction, thank you. The code for this article comes mainly from open source books: Unity EssentialsFirst, the texture in Unity shader1. Sim

In WebGL, the opengl-es-2.0 API is called, and the opengl-es is designed for embedded devices, which, like other devices, use GLSL (GL shading Language) to write fragment programs and execute on the GPU shader. To complete rendering of the object. GLSL plays a very important role in it, so to play good webgl, we have to understand GLSL, this article mainly introduces the basic use of shader and composition.

To achieve special effects, especially some post-processing effects, it is often necessary to replace each object's shader with another set of shader for rendering to the texture, then compositing or superimposed on the final screen in some way.A little more complicated, maybe different objects are replaced with shader.Camera.renderwithshader in Unity enables this functionality.The following is an official

began to learn unity also has one months, before you want to learn things summed up, recorded to facilitate their own later review, but work too busy always forget this thing, recently finally have time, intend to learn the things recorded every day. There are two reasons to write this article: 1. Many of the ideas are thought to be at school, but they have been forgotten for some time. 2. Used to look at other people's blog, and then suddenly found no other people's blogs, and then some content

In Android, the Shader class is provided for rendering images and some geometric figures. The Shader class includes five direct subclasses: BitmapShader, ComposeShader, LinearGradient, RadialGradient, and SweepGradient. Here, BitmapShader is used for image rendering; ComposeShader is used for hybrid rendering; LinearGradient is used for linear rendering; RadialGradient is used for Ring rendering; and SweepG

Cg=c for graphics C-language superset for computer graphics programmingPrerequisite Knowledge Points:1.CG code must be usedCgprogram。。。ENDCG, surround it.2. The main function name of the vertex shader and fragment shader can be arbitrary, but it needs to be #pragma vert and #pragma fragment and fully match the main function name, shader will find the portal3.FLOA

Recently in the optimization of doing unity Shader Forge and Marmoset, TA has encountered a shadow display problem, specifically as follows:In the forward rendering state, the static scene uses Blendlayer, which is the shader class generated by the shader forge, and when the dynamic character goes near a static object using Lightmap Bake map, the directional ligh

For example, supporting per-material-A-nice-to-make-shader more flexible, but if-you-always-leave that color set To white then it's useless computations performed for each vertex or pixel rendered on screen. Just calculate the parts you need and eliminate any unnecessary parts. For example,

Overview of the coloring of the OpenGL ES Shader Language (Official Document chapter II)In fact, OpenGL es coloring language is two closely related languages. These languages are used to create shaders in the OpenGL ES processing pipeline's programmable processor. In this document, unless otherwise noted, a language feature is available for all languages, and general usage will treat them as a language. Specific languages will indicate their target pr

Android shader Renderer The Renderer in android is mainly used as a Child class of shader. shader inherits from object and its Child classes include: 1. BitMapShader: The BitMapShader is a bitmap Renderer. You can find its name, BitmapShader is a sub-class of Shader. You can use Paint. setShader (

Only one vertex shader is active at a time. You can have multiple vertex shader, if an object has a special transform or light, you can choose the appropriate vertex shader to accomplish this task.You may want to use vertex shaders on each object or on each grid, for example, 10 meshes, you can use 10 different vertex shader
