Struct easygpu_lyon::ShapeBuilder
source · pub struct ShapeBuilder {
pub default_color: [f32; 4],
/* private fields */
}
Expand description
Builds a shape using lyon for tesselation
Fields§
§default_color: [f32; 4]
This RGBA color is used when tesselating a path with no color data (Attributes in lyon terminology)
Implementations§
source§impl ShapeBuilder
impl ShapeBuilder
sourcepub fn new(zdepth: f32, default_color: [f32; 4]) -> Self
pub fn new(zdepth: f32, default_color: [f32; 4]) -> Self
Create a new ShapeBuilder with a given ZDepth
Arguments
zdepth
- The z depth for shapes in this builder to have
sourcepub fn prepare(&self, renderer: &Renderer) -> Shape
pub fn prepare(&self, renderer: &Renderer) -> Shape
Prepare and load this builder into the renderer.
This does not consume the builder, because wgpu copies the buffer rather than taking ownerhip.
sourcepub fn fill(
&mut self,
path: &Path,
options: &FillOptions
) -> Result<(), TessellationError>
pub fn fill( &mut self, path: &Path, options: &FillOptions ) -> Result<(), TessellationError>
Fill an arbitrary path from lyon::path
sourcepub fn stroke(
&mut self,
path: &Path,
options: &StrokeOptions
) -> Result<(), TessellationError>
pub fn stroke( &mut self, path: &Path, options: &StrokeOptions ) -> Result<(), TessellationError>
Stroke an arbitrary path from lyon::path
