Real-time watercolor illustrations of plants using a blurred depth test

Content Provider ACM Digital Library
Author Deussen, Oliver Luft, Thomas
Abstract We present techniques to create convincing high-quality watercolor illustrations of plants. Mainly focusing on the real-time rendering, we introduce methods to abstract the visual and geometrical complexity of the original 3D plant models that are obtained from the photorealistic rendering. Additionally, we integrate detail layers to emphasize the structure, the texture, and the lighting. We distinguish between particle based, texture based, and line stroke based detail primitives, which provide a wide application range for the individual tree and plant models. To support smooth transitions and the frame-to-frame coherence during an animation, we introduce a so-called blurred depth test to perform depth comparisons. This blurred depth test is utilized for the visibility computations of the detail primitives and for the creation of a soft shadowing effect. With our techniques, we create an appropriate lighting and shadowing of the scene, and achieve a high frame-to-frame coherence. For the final watercolor appearance, we apply a formerly published approach that is implemented using hardware shaders.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
