Examples
A 2D flat art style campsite poster with the text “{{appName}} Seedream 3.0 API”. The scene includes mountains, brown tents under a sunny sky, a rabbit, a deer, some birds, green grass, and a flowing river, all illustrated in clean vector art.
An astronaut in an orange suit, floating in the void of a vast galaxy, illustrated in black-and-white manga style.
An isometric cross-section of the deep sea, featuring a diver mid-dive exploring ancient ruins and glowing coral in search of hidden treasure. One side of the scene shows vibrant sea life such as jellyfish, rays, and schools of fish, while the other side reveals mysterious shipwreck debris and treasure chests. The background uses a rich gradient of deep blues to contrast with dark underwater elements. Digital art style, high resolution, hyper-realistic 3D rendering in Octane Render and Unreal Engine.
