Struct weldr::DrawContext

pub struct DrawContext {
    pub transform: Mat4,
    pub color: u32,
}

Drawing context used when iterating over all drawing commands of a file via SourceFile::iter().

Fields

transform: Mat4

Current transformation matrix for the drawing command. This is the accumulated transformation of all parent files.

When drawing a primitive (line, triangle, quad), the actual position of vertices is obtained by transforming the local-space positions of the drawing command by this transformation matrix.

let v0 = draw_ctx.transform * cmd.vertices[0];

color: u32

Current color for substitution of color 16.
