Python animation

Abstract This program is an animated, frame-based visualization system built using asynchronous execution and dynamic memory control. It displays a sequence of frames each representing a computational snapshot with values that change over time. The system uses a live calculation engine to simulate evolving conditions (like load or complexity), while presenting each frame in a clean, time-controlled format. A key feature of the system is its reversible memory buffer: the most recent frames are stored and can be replayed in reverse when triggered by user input. This creates a flipbook-style animation with temporal control, allowing users to rewind recent activity and then resume forward motion. The queue-based logic ensures that frame order is preserved, and the program remains responsive and modular. This design models how systems can visualize change over time, evaluate ongoing complexity, and offer interactive control—all while maintaining asynchronous, non-blocking performance. Updated Feature: Press ‘r’ to Trigger Reverse Playback Key Changes: • The rollback() is no longer triggered automatically. • The animation loop now checks for keyboard inputusing asyncio.to_thread() and input() to avoid blocking the event loop. • When you press 'r', it triggers the reverse animation. import asyncio import os import random from collections import deque def reset_screen(): os.system('cls' if os.name == 'nt' else 'clear') # --------------------------- # Abstract Payload Evaluation # --------------------------- async def evaluate_payload(index): A = random.uniform(1, 10) B = random.uniform(10, 100) C = random.uniform(5, 50) complexity = (A * B) / (C + 1e-6) await asyncio.sleep(0.01) return A, B, C, complexity # --------------------------- # Frame Object # --------------------------- class Frame: def __init__(self, idx, interval=0.05): self.idx = idx self.text = "" self.interval = interval async def generate(self): A, B, C, value = await evaluate_payload(self.idx) pattern = "." * (self.idx % 10 + 1) self.text = ( f"Frame {self.idx}\n" f"Visual: {pattern}\n" f"Measure A: {A:.2f}, B: {B:.2f}, C: {C:.2f}\n" f"Value: {value:.2f}" ) async def render(self): reset_screen() await self.generate() print(self.text) await asyncio.sleep(self.interval) # --------------------------- # Temporal Queue with Manual Reverse # --------------------------- class TemporalQueueEngine: def __init__(self, total=20, memory=6): self.forward = deque(Frame(i + 1) for i in range(total)) self.cache = deque() self.memory = memory async def listen_for_reverse(self): # Run blocking input in a thread return await asyncio.to_thread(input, "Press 'r' to reverse or Enter to continue: ") async def execute(self): print("[System] Initiating animation...\n") while self.forward: item = self.forward.popleft() await item.render() self.cache.appendleft(item) if len(self.cache) > self.memory: self.cache.pop() # Listen for reverse trigger user_input = await self.listen_for_reverse() if user_input.strip().lower() == 'r': await self.rollback() print("\n[System] Playback complete.") async def rollback(self): print("\n[System] Reversal Triggered — Executing in Reverse...\n") for frame in list(self.cache): await frame.render() print("\n[System] Resuming forward path...\n") # --------------------------- # Main Entry Point # --------------------------- async def main(): queue = TemporalQueueEngine(total=20, memory=6) await queue.execute() if __name__ == "__main__": asyncio.run(main()) How it Works (in Simple Terms): • As the animation plays, it asks you: “Press ‘r’ to reverse or Enter to continue” • If you press ‘r’, it rewinds and shows the last few frames again. • If you press Enter, it just keeps going forward.
