The material texture is an image that maps to object's surfaces to provide color details and more.材质纹理是映射到对象表面以提供颜色细节等的图像。

The syntax is the following:语法如下:

TextureDimension name = "directory/name.format"  <attributes>
If the name of the texture is not specified, then the name will be equal to the texture source type. The following declarations are equal:
Texture <source="gbuffer_normal" unit=0>
Texture gbuffer_normal <source="gbuffer_normal" unit=0>
Texture <source="gbuffer_normal" unit=0>
Texture gbuffer_normal <source="gbuffer_normal" unit=0>

Types of Textures纹理类型#

  • Texture (or Texture2D) — a two-dimensional (2D) texture image where each element is a floatTexture (或 Texture2D) — 二维 (2D)质地每个元素都是浮点数的图像
  • TextureCurve — 2D curves in a form of a textureTextureCurve — 纹理形式的 2D 曲线
  • Texture2DArray — a homogeneous array of 2D textures where each texture has the same data format, filtering type, and dimensions (including mipmap levels)Texture2DArray — 2D 纹理的同构数组,其中每个纹理具有相同的数据格式、过滤类型和维度(包括 mipmap 级别)
  • Texture2DUint — a two-dimensional texture image where each element is an unsigned intTexture2DUint — 一个二维纹理图像,其中每个元素都是一个无符号整数
  • Texture2DInt — a two-dimensional texture image where each element is an intTexture2DInt — 一个二维纹理图像,其中每个元素都是一个int
  • Texture3D — is a volume texture that contains 3D texelsTexture3D — 是包含 3D 纹素的体积纹理
  • TextureCube — an array of 2D textures with 6 elements for each face of the cubeTextureCube — 2D 纹理数组,立方体的每个面都有 6 元素

Usage Examples使用示例#

	Texture diffuse = "core/textures/common/" <unit=0 auto_init=true>
float4 texture_color = TEXTURE(tex_diffuse, IN_UV);

If auto_init is set to true, the texture will be declared automatically in the shader the following way:如果 auto_init 设置为 true,纹理将通过以下方式在着色器中自动声明:

INIT_TEXTURE(0, tex_diffuse)

The texture can now be accessed in the shader via the tex_diffuse name. You don’t need to initialize it separately.现在可以通过 tex_diffuse 名称在着色器中访问纹理。您不需要单独初始化它。

The engine has some default textures. You can use shortcuts to reference them (instead of specifying the full path).引擎有一些默认纹理。您可以使用快捷方式来引用它们(而不是指定完整路径)。

Shortcut Full directory path
white core/textures/common/
black core/textures/common/

red core/textures/common/
grain core/textures/common/
cube_white core/textures/common/

    Texture2D // unit = 0 assigned by default
    Texture2D <unit=5> // unit = 5 assigned by user
    Texture3D  // unit = 2 assigned by default, because it is the third defined texture in the material
