This is a shader implementation of Real-Time Hatching, Praun et al. [2001]. The scene contains a real-time rendering of hatching strokes over various objects. They use tonal art maps containing different stroke sizes and density at various resolutions. Using these tonal art maps, we can render strokes on complex surfaces.
The scene is filled with 3D objects featuring ambient and diffuse lighting. The objects cast shadows on each other based on the light using shadow maps. The user may move the light source around.
The scene contains a bump-mapped floor and a bump-mapped swimming fish. The fish is a cylinder which has been warped using a vertex program. The “wriggles” of the fish body are simulated using a sin wave which starts from the fish midline towards the tail. This animation is controlled using an interface which allows the […]
Texture mapped a 4-sided room such that one wall has front-side culling applied. The floor is texture mapped using a checkerboard image and also feature mip mapping. The walls of the room are a repeated brick texture. There is a floating sphere in the center of the room texture mapped with the image of the […]
