Module re_renderer::transform

Transformation utilities.

Some space definitions to keep in mind:

Texture coordinates:

• origin top left
• full texture ([left; right], [top; bottom]): ([0; 1], [0; 1])

NDC:

• origin center
• full screen ([left; right], [top; bottom]): ([-1; 1], [1; -1])

Pixel coordinates:

• origin top left
• full screen ([left; right], [top; bottom]): ([0; screen_extent.x], [0; screen_extent.y])

Structs

• RectTransform
  Defines a transformation from a rectangular region of interest into a rectangular target region.

Functions

• ndc_from_pixel
  Transforms texture coordinates to normalized device coordinates (NDC).
• ndc_from_texcoord
  Transforms texture coordinates to normalized device coordinates (NDC).
