What does TEXCOORD0 mean?

What does TEXCOORD0 mean?

POSITION is the vertex position, typically a float3 or float4 . NORMAL is the vertex normal, typically a float3 . TEXCOORD0 is the first UV coordinate, typically float2 , float3 or float4 . TANGENT is the tangent vector (used for normal mapping), typically a float4 . COLOR is the per-vertex color, typically a float4 .

What is a Cginc?

Lighting. cginc – standard surface shader lighting models; automatically included when you’re writing surface shaders. TerrainEngine.cginc – helper functions for Terrain. A Terrain GameObject adds a large flat plane to your scene and you can use the Terrain’s Inspector window to create a detailed landscape.

What is Appdata_full?

appdata_tan : vertex consists of position, tangent, normal and one texture coordinate. appdata_full : vertex consists of position, tangent, normal, four texture coordinates and color.

What language are Unity shaders written in?

HLSL language
In Unity, shader programs are written in a variant of HLSL language (also called Cg but for most practical uses the two are the same).

What is clip space?

Clip space is where the space points are in after the point transformation by the projection matrix, but before the normalisation by w . NDC space is the space points are in after the normalisation by w .

What is shader graph unity?

Shader Graph lets you easily author shaders by building them visually and see the results in real-time. You create and connect nodes in a network graph instead of having to write code.

What is generate shader includes?

In Unity, the process of generating the HLSL code from C# code is called generating shader includes. When Unity generates shader includes, it parses all the C# files in the project and, for every file that contains a struct with a GenerateHLSL attribute, generates corresponding HLSL code.

How do you make a shader in unity?

Create your new shader by right clicking in the Assets window and selecting Create->Shader->Standard Surface Shader. Figure 5: Creating a new shader. You may name the shader whatever you wish, but the remainder of this writing will refer to this shader as MyShader.

What is unity shader?

Rendering in Unity is done with Materials, Shaders and Textures. Shaders are small scripts that contain the mathematical calculations and algorithms for calculating the colour of each pixel rendered, based on the lighting input and the Material configuration. Textures are bitmap images.

What does a fragment shader do?

A Fragment Shader is the Shader stage that will process a Fragment generated by the Rasterization into a set of colors and a single depth value. The fragment shader is the OpenGL pipeline stage after a primitive is rasterized. Fragment shaders take a single fragment as input and produce a single fragment as output.

Is Unity HLSL or GLSL?

In Unity, shader programs are written in a variant of HLSL language (also called Cg but for most practical uses the two are the same). Later on, Unity will convert the Cg shader into HLSL, GLSL or Metal based on what it needs (probably the target platform).
