Trait implemented by graphics backends responsible for rendering the physics scene.

The only thing that is required from the graphics backend is to be able to render a colored line. Note that the color is only a suggestion and is computed from the DebugRenderStyle. The backend is free to apply its own style, for example based on the object being rendered.

Required Methods

fn draw_line( &mut self, object: DebugRenderObject<'_>, a: Point<Real>, b: Point<Real>, color: [f32; 4] )

Draws a colored line.

Note that this method can be called multiple time for the same object.

Provided Methods

fn filter_object(&self, _object: DebugRenderObject<'_>) -> bool

Predicate to filter-out some objects from the debug-rendering.

fn draw_polyline( &mut self, object: DebugRenderObject<'_>, vertices: &[Point<Real>], indices: &[[u32; 2]], transform: &Isometry<Real>, scale: &Vector<Real>, color: [f32; 4] )

Draws a set of line.

fn draw_line_strip( &mut self, object: DebugRenderObject<'_>, vertices: &[Point<Real>], transform: &Isometry<Real>, scale: &Vector<Real>, color: [f32; 4], closed: bool )

Draws a chain of line.
