Struct ColorGeo

pub struct ColorGeo { /* private fields */ }

Includes a 4x4 homogeneous geometry transformation, a 4x4 homogenous color transformation, a saturation modifier, and a color lookup table (LUT).

Implementations

impl ColorGeo

pub fn new( gpu: &WGPU, color_texture: &Texture, lut_texture: &Texture, color_target: ColorTargetState, ) -> Self

Creates a new ColorGeo phase.

pub fn set_color_target(&mut self, gpu: &WGPU, color_target: ColorTargetState)

Changes the postprocessing phase’s color target, re-creating the pipeline if needed

pub fn set_post( &mut self, gpu: &WGPU, trf: [f32; 16], color_trf: [f32; 16], sat: f32, )

Updates simple parameters for color-geometry transforms. To replace the lut, call ColorGeo::replace_lut.

pub fn replace_color_texture(&mut self, gpu: &WGPU, color: &Texture)

Replaces the color texture resource used by this postprocessing stage (for example, because the color target has changed size).

pub fn replace_lut(&mut self, gpu: &WGPU, lut: &Texture)

Replaces the lookup table used by this postprocessing stage. The LUT should be a 3D texture.

pub fn render<'s, 'pass>(&'s self, rpass: &mut RenderPass<'pass>)

where 's: 'pass,

Renders onto the given renderpass.

pub fn transform(&self) -> [f32; 16]

Returns the current geometric transform (a 4x4 homogeneous column-major matrix).

pub fn color_transform(&self) -> [f32; 16]

Returns the current color transform (a 4x4 homogeneous column-major matrix).

pub fn saturation(&self) -> f32

Returns the current saturation modifier (0.0 means identity, negative decreases and positive increases saturation).

pub fn set_transform(&mut self, gpu: &WGPU, mat: [f32; 16])

Sets the geometric transform (a 4x4 homogeneous column-major matrix).

pub fn set_color_transform(&mut self, gpu: &WGPU, mat: [f32; 16])

Sets the color transform (a 4x4 homogeneous column-major matrix).

pub fn set_saturation(&mut self, gpu: &WGPU, sat: f32)

Sets the saturation modifier (0.0 means identity, negative decreases and positive increases saturation).
