code/TextureInput

A picture wired into this tex/Builder, as a texture.

Texture

Wire a picture into one of the tex/Builder's inputs and this node gives it as a texture, to read with the nodes that read any texture. code/TextureSample2D with a code/Sampler reads its colour at a uv, blending between pixels. code/TextureTexel reads one pixel exactly, at the pixel being written or next to it. code/TextureSize gives its size in pixels.

A 3D texture wired there (a tex/Volume, or a 3D tex/Builder) comes out as a 3D texture: read it with code/TextureTexel, or with code/TextureSample3D in VALUE mode at a uvw. Only a 3D tex/Builder can read one: in a 2D builder the build is refused with a message naming the input.

The colour comes out in linear light, whatever the picture holds: an 8-bit sRGB picture is decoded before anything blends it. A 32-bit float picture is refused, since a sampler cannot blend it.

Parameters

Name Type What it does
inputIndex UInt8 Which of the tex/Builder's inputs to read, 0 to 3. Something must be wired there.
