Vector field visualization is one of the most challenging research issues for Visualization in Scientific Computing

which enable an efficient insight into the physical essence behind large|scale but abstract data obtained from scientific computation and experimentation

and has been paid more and more attentions

and widely used for those areas such as Computational Fluid Dynamics

aerodynamics

atmospherical physics and meteorology analysis. This paper extended LIC to VolumeLIC for 3D vector field visualization by volume rendering 3DLICed volumetric texture. Sparse Line Noise was designed and combined with Ramp Convolution Kernel to improve VolumeLIC image

with direction and depth cueing enhanced. HRCK was presented to create smooth cyclic animation without any pulsation. VolumeLIC Probe was further proposed for interactive insight deep into 3D vector fields.Finally

Closely based on above research work

VF|VTK(Vector Field Visualization Tool Kit) was exclusively designed and developed for three practical applications

the Visualization of the mantle movement

the flow field

and the high altitude airflow field. These applications have indicated that the methods presented in this paper are convenience

efficiency and robustness in practice.
