Backend TUI API

The TUI backend consumes @frontend.DrawList and emits character frames.

Types

• TuiRenderConfig: width, height, terminal y-scale, shade ramp, and background pattern.
• FrameBuffer: cells plus depth buffer.
• TuiImage: one static rendered character image.
• TuiFrame: one rendered character frame.
• TuiSequence: width, height, fps, and a list of TuiFrames.

Functions

• FrameBuffer::new(width, height, background_pattern).
• TuiRenderConfig::sized(width, height): default styling at an explicit viewport size.
• FrameBuffer::set_pixel_if_closer(x, y, depth, pixel).
• apply_terminal_y_scale(point, height, terminal_y_scale).
• draw_triangle_z(buffer, p0, p1, p2, pixel).
• render_draw_list(draw_list, config).
• render_frame(draw_list, config).
• render_scene(scene, render_view, config).
• render_luma_buffer(buffer, config).
• render_luma_frame(buffer, config).
• TuiImage::new(width, height, content).
• encode_tui_image(image) / decode_tui_image(text).
• TuiSequence::new(width, height, fps) / push_frame(content).
• encode_tui_sequence(sequence) / decode_tui_sequence(text).
