<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />

<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />

<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />
<br />

<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />
<br />

<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />
<br />

<hr />
<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />

<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />
<br />

<hr />
<div>== What is a Shader? ==<br />
A shader is a bit of computer code that is commonly used to describe how a surface will be rendered. It takes some inputs (textures, vertices, view angles, etc.), does some changes to them, then tells the game renderer to render them. <br />
<br />
Shaders are typically used for interactive rendering, like in a 3d game, where the view is rendered in real-time at 30 fps (or better). <br />
<br />
This page is all about these "real-time" shaders, which are optimized to render efficiently, trading better performance for less accuracy. <br />
<br />
Conversely, "offline" shaders are used with non-real-time renderers, like V-Ray or mental ray, and have more accurate effects like ray-tracing and sub-pixel filtering, but they are non-interactive (they can take several minutes to render each frame).<br />

<div>A Texture Atlas describes the method of packing many separate textures together into a single texture. Other common names for this are "decal sheet", "packed texture".<br />
<br />
Atlases save texture fetches, which can help improve the [[FPS|frame rate]].<br />
<br />
Each of the textures can be [[Tiling|tiled]] with themselves, just like a regular tiling texture. <br />
<br />
The textures can either be cropped out of the atlas by adding more edges to the model and cutting up the [[Texture Coordinates|texture coordinates]] (at the expense of increasing the [[Polygon_Count#Triangle_Count_vs._Vertex_Count|vertex count]]), or the textures can be arranged as [http://udn.epicgames.com/Three/TerrainAdvancedTextures.html#Texture%20Packing:%20Implementing%20large%20texture%20tile%20sets sub-tiles] and cropped out using a [[Shaders|shader]] (at the expense of increasing the shader instructions).<br />

== Atlas Methods ==<br />
There are two common atlas methods: one divides a single bitmap into multiple sub-maps (this is usually what artists mean when they say "atlas"), the other method packs different grayscale maps into each color channel (this can be called a multimap or [[ChannelPacking|channel packing]]). The two methods are not exclusive, they can also be used together in the same bitmap.<br />

== Gutters ==<br />
When a game model is textured using a single texture sheet, the texture will have typically have UV'd areas ([[Texture Coordinates|UV shells]]) and blank areas between them (gutters). <br />
<br />
The width of the gutter needs to be wide enough to accommodate how much [[EdgePadding]] you need. This varies depending on how large the texture is and the [[Texture filtering|texture filtering]] type used by the game renderer.<br />

<hr />
<div>Channel packing means using different grayscale images in each of a texture's image channels... Red, Green, Blue, and optionally Alpha. <br />
<br />
These channels are usually used to represent traditional RGB color data, plus Alpha transparency. However each channel is really just a grayscale image, so different types of image data can be stored in them.<br />
<br />
Individual channels can be extracted by a [[Shaders|shader]] to use them for particular effects, for example the red channel for glow, green channel for specular, blue channel for sound types, alpha channel for physics info, etc. Each channel can have a totally different layout, and thus use different [[TextureCoordinates|UVs]]. <br />
<br />
Games use this technique to avoid loading separate grayscale images, which saves [[Memory]]. However this does increase shader complexity, which can increase [[GameRenderingTerminology#Draw Call|draw calls]]. <br />
<br />
[[RMA]] is a type of packed map which contains [[Roughness map|Roughness]] + [[Metallic map|Metallic]] + [[Ambient occlusion map|Ambient occlusion]], which are used with [[PBR]] (Physically Based Rendering). <br />
<br />
== Swizzle ==<br />
Swizzling means to change the order of the color channels in a texture. For example, moving the red channel into the alpha channel, to prepare an image for [[Normal_Map_Compression#DXT5nm_Compression|DXT5nm compression]].<br />
<br />
Usually swizzling is done to create better results when using image compression, since the green channel sometimes uses more bits. This is because [http://www.physicsclassroom.com/class/light/Lesson-2/Visible-Light-and-the-Eye-s-Response the human visual system is biased] to perceive more values in the green range than in red or blue.<br />
<br />
See [[Normal Map Compression]].<br />
<br />
== Examples ==<br />

<hr />
<div>Face weighted normals (FWN) is a technique to improve shading for 3d models. Shading can be improved by adding bevels and altering the [[VertexNormal|vertex normals]] to be perpendicular on the larger flat polygons. This forces the shading to be blended across the smaller bevel faces, rather than across the entire model. <br />
<br />
However, the added bevels will often create long thin triangles, which can significantly reduce rendering performance. See [http://blog.selfshadow.com/2012/11/12/counting-quads/ Counting Quads].<br />
