A Skinned Tetrahedral Mesh for Hair Animation and Hair-Water Interaction
IEEE Transactions on Visualization and Computer Graphics
|July 12, 2018
Summary
We introduce an efficient framework for animating millions of hairs and simulating hair-water interactions. This method uses a kinematically skinned tetrahedral mesh for plausible and dynamic hair behavior, reducing simulation costs.
Area of Science:
- Computer Graphics
- Simulation and Modeling
Background:
- Realistic hair animation and interaction are computationally intensive.
- Existing methods struggle with simulating millions of hairs and complex phenomena like hair-water interaction.
Purpose of the Study:
- To develop a novel, efficient framework for animating millions of hairs.
- To enable realistic simulation of hair-water interactions.
Main Methods:
- Embedding hairs into a tetrahedralized volume mesh, kinematically skinned to an animated character.
- Utilizing a secondary, spring-endowed mesh for dynamic hair behavior, anchored to the primary kinematic mesh for efficiency.
- Integrating dynamic simulations into a blendshape system for artist control and iterative refinement.
Main Results:
- Achieved visually plausible hair animation with millions of hairs.
- Demonstrated efficient simulation of dynamic hair behaviors using weak springs anchored to a kinematic mesh.
- Established a foundation for simulating complex hair-water interactions, including drag and adhesion forces.
Conclusions:
- The proposed framework significantly enhances the efficiency and plausibility of hair animation.
- The method provides a robust solution for complex hair dynamics and interactions, particularly hair-water effects.
- This approach offers artists greater control and iterative capabilities within blendshape systems.

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

01:20Accessory Structures of the Skin: Hair Growth and Types
2.4K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

Mesh analysis is a valuable method for simplifying circuit analysis using mesh currents as key circuit variables. Unlike nodal analysis, which focuses on determining unknown voltages, mesh analysis applies Kirchhoff's voltage law (KVL) to find unknown currents within a circuit. This method is particularly convenient in reducing the number of simultaneous equations that need to be solved.

Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.
