Struct rerun::external::re_renderer::RectTransform

source · 
pub struct RectTransform {
    pub region_of_interest: RectF32,
    pub region: RectF32,
}
Expand description

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

This is “pan and scan”.

Transforms the range of region_of_interest to the range of region.

Fields§

§region_of_interest: RectF32

The region of the scene that should be visible.

§region: RectF32

The full scene.

Implementations§

source§

impl RectTransform

source

pub const IDENTITY: RectTransform = _

No-op rect transform that transforms from a unit rectangle to a unit rectangle.

source

pub fn to_ndc_scale_and_translation(&self) -> Mat4

Computes a transformation matrix that applies the rect transform to the NDC space.

This matrix is expected to be the left most transformation in the vertex transformation chain. It causes the area described by region_of_interest to be mapped to the area described by region. Meaning, that region represents the full screen of the NDC space.

This means that only the relation of the rectangles in RectTransform is important. Scaling or moving both rectangles by the same amount does not change the result.

source

pub fn scale(&self) -> Vec2
