Title: 3D Hatching


1
3D Hatching
Praun, E., Hoppe, H., Webb, M., and Finkelstein,
A. Real-time Hatching In Computer Graphics
(SIGGRAPH 2001), pp.579-584 (2001)
April 4, 2003 Sung Yong SHIN Computer Science Div.
2
A real-time system for non-photorealistic
rendering of hatching strokes over arbitrary
(3D) surfaces.
Interactive applications - games - interactive
technical drawing - artistic virtual environment
Changes in camera, lighting, and scene Dynamic
stroke rearrangement need temporal coherency !!!
3
Challenges - limited run-time computation -
frame-to-frame coherency among strokes - control
of stroke size and density under dynamic
viewing conditions How ? TAM ( tonal art map
) Hardware multi-texturing Lapped texturing
direction fields
