Luna::VG::IShapeDrawList

Represents a draw list that contains shapes to be drawn.

interface Luna::VG::IShapeDrawList : public virtual Interface

Base type

• Interface

Member functions

• virtual void reset()=0

  Resets the draw list. The call clears all shapes recorded, but retains their memory and resources, so they can be reused for new shapes.

• virtual Vector< f32 > & get_shape_points()=0

  Gets shape points that are recorded in internal shape buffer.

• virtual void set_shape_buffer(RHI::IBuffer *shape_buffer)=0

  Sets the shape buffer used for the following draw calls.

• virtual RHI::IBuffer * get_shape_buffer()=0

  Gets the current set shape buffer. See remarks of set_shape_buffer for details.

• virtual void set_texture(RHI::ITexture *tex)=0

  Sets the texture to be sampled when rendering the succeeding shapes.

• virtual RHI::ITexture * get_texture()=0

  Gets the currently set texture.

• virtual void set_sampler(const RHI::SamplerDesc *desc)=0

  Sets the sampler state to be used when sampling bound textures.

• virtual RHI::SamplerDesc get_sampler()=0

  Gets the sampler state currently set.

• virtual void set_origin(const Float2 &origin)=0

  Sets the origin point for the following draw calls.

• virtual Float2 get_origin()=0

  Gets the origin point for the following draw calls.

• virtual void set_rotation(f32 degrees)=0

  Sets the rotation for the following draw calls.

• virtual f32 get_rotation()=0

  Gets the rotation for the following draw calls.

• virtual void draw_shape_raw(Span< const Vertex > vertices, Span< const u32 > indices)=0

  Draws one shape by submitting vertices and indices directly.

• virtual void draw_shape(u32 begin_command, u32 num_commands, const Float2U &min_position, const Float2U &max_position, const Float2U &min_shapecoord, const Float2U &max_shapecoord, u32 color=0xFFFFFFFF, const Float2U &min_texcoord=Float2U(0.0f), const Float2U &max_texcoord=Float2U(0.0f))=0

  Draws one shape. The shape is drawn by adding one draw rect (two triangles) to the list.

• virtual RV compile()=0

  Builds render resources and draw calls that can be used for drawing glyphs.

• virtual RHI::IBuffer * get_vertex_buffer()=0

  Gets the compiled vertex buffer used for rendering glyphs in this draw list.

• virtual u32 get_vertex_buffer_size()=0

  Gets the number of vertices in the vertex buffer returned by get_vertex_buffer.

• virtual RHI::IBuffer * get_index_buffer()=0

  Gets the compiled index buffer used for rendering glyphs in this draw list.

• virtual u32 get_index_buffer_size()=0

  Gets the number of indices in the index buffer returned by get_index_buffer.

• virtual void get_draw_calls(Vector< ShapeDrawCall > &out_draw_calls)=0

  Gets an array of draw calls that should be invoked to draw glyphs in this draw list.
