Prompt: “Paint a majestic alpine mountain landscape at sunrise as a realistic oil painting, entirely from scratch in code, and show it being painted stroke by stroke. A towering snow-covered mountain rises above a deep glacial valley, its jagged peaks catching the first golden light of dawn. Wisps of mist drift between dark pine forests, a turquoise river winds through the valley, and a rustic wooden cabin glows warmly beside the water. The upper peaks burn with amber sunlight while the lower slopes remain submerged in cool blue shadows. Tiny waterfalls tumble down sheer cliffs, wildflowers cling to the foreground rocks, and a few distant birds glide through the luminous morning sky. Make it look like a masterpiece by a great landscape painter: extraordinary atmospheric perspective, physically convincing natural light, rich oil pigments, expressive brushwork, layered glazes, textured canvas grain, and thick impasto on sunlit snow, sparkling water, and illuminated foliage. Every rock, cloud, tree, reflection, and mountain ridge should feel deliberately painted, with beautiful color relationships and convincing depth. Show the entire painting process from a completely blank, primed canvas: Lay down the warm canvas ground and loose charcoal composition sketch. Establish the dark underpainting and broad tonal masses. Block in the mountain silhouettes, valley, forests, river, and sky with large visible brushstrokes. Build up successive layers of color, atmospheric haze, snow textures, and reflected light. Refine the trees, rocky surfaces, flowing water, distant peaks, and delicate foreground details. Finish with confident, thick impasto highlights, luminous glazes, and small, precise final strokes. Animation requirements: This must be a genuine procedural painting animation, not a finished image fading in or appearing all at once. Render actual brushstrokes progressively onto the canvas, with each stroke remaining visible as the painting develops. Use evolving stroke sizes, pressure-like variations, natural pigment mixing, bristle textures, and layered paint accumulation. The canvas should begin completely blank, and the finished masterpiece must be fully painted at exactly 25 seconds. Technical constraints: Use only code and native drawing primitives. No external images, image textures, libraries, frameworks, imported assets, or pre-rendered artwork. Generate every brushstroke, texture, reflection, cloud, and lighting effect algorithmically. Keep the animation smooth, the composition coherent, and the rendering efficient. Quality goal: Aim for the visual richness of a museum-quality traditional oil painting, with cinematic sunrise lighting, intricate natural detail, convincing depth, and an artistically sophisticated composition. Avoid generic procedural patterns, repetitive textures, flat vector shapes, and synthetic-looking gradients. Every stroke should contribute to the illusion of a real painter working on a physical canvas. Make the final scene breathtaking enough to stand on its own as a finished work of art, while ensuring the painting process itself is just as beautiful to watch.”
