A surface definition module of a hair/fur pipeline may be used to define a surface. An instancing module is used to instance hairs. An instanced hair database coupled to the instancing module is used to store hair data. The instancing module retrieves hair data from the instanced hair database to allow for a relatively large number of hairs to instanced. A display module is used to display the instanced hairs with respect to the surface.

A surface definition module of a hair/fur pipeline may be used to generate a shape defining a surface and an associated volume. A control hair module may be used to fill the volume with control hairs and an interpolation module may be used to interpolate final hair strands from the control hairs.

Fill-volume techniques for use in a hair/fur pipeline

Systems and methods are disclosed to create a realistic and dynamic model of an animated object, such as hair or cloth, by employing control vertices and control entities that make up an animated object. The control vertices are used as polyhedral vertices in the creation of a polyhedral mesh, such as a tetrahedral mesh, and a constraint is employed during simulation in which the polyhedral volume is preserved. Using the systems and methods, the workflow may be significantly improved and costs significantly lowered.

A lighting module of a hair/fur pipeline may be used to produce lighting effects in a lighting phase for a shot and an optimization module may be used to: determine if a cache hair state file including hair parameters exists; and determine if the cache hair state file includes matching hair parameters to be used in the shot, and if so, the hair parameter values from the cache hair state file are used in the lighting phase.

Hair caching optimization techniques for use in a hair/fur pipeline

A surface definition module of a hair/fur pipeline may be used to define a surface and an optimization module may be used to: create a bounding box for a set of hairs; determine whether the bounding box is visible; and if the bounding box is visible, hair associated with the visible bounding box is rendered upon the surface.

Sub-patch optimization techniques for use in a hair/fur pipeline

A hair pipeline utilizes a surface definition module to define a surface and a control hair and a hair motion compositor module combines different control hair curve shapes associated with the control hair and the surface. In particular, the hair motion compositor module generates a static node defining a static control hair curve shape; generates an animation node defining an animation control hair curve shape; and combines the static control hair curve shape of the static node with the animation control hair curve hair shape of the animation node to produce a resultant control hair curve shape for the control hair.

Hair motion compositor system for use in a hair/fur pipeline

A system and method to generate digital representations of hair or animal fur on surfaces. In one embodiment the system and method includes methods to automatically place hairs on surfaces, comb the placed hairs, adjust the hairs on surface boundaries to ensure continuity across surface patches, selectively break hairs along fur tracks, and selectively clump hairs to provide wet fur looks. Rendering techniques are applied to the hairs to produce realistic two-dimensional images.

Method and apparatus for the digital creation of fur effects

A surface definition module of a hair/fur pipeline may be used to define a surface. An interpolation module may be used to interpolate at least one final hair on the surface based upon at least one control hair. An effects module including an effects pipeline may be utilized to apply a plurality of effects to the final hair in a user-defined order to generate a modified final hair that may be ultimately rendered.

Multiple instantiable effects in a hair/fur pipeline

A surface definition module of a hair/fur pipeline may be used to define a surface and an optimization module may be used to determine whether a hair is to be rendered upon the surface. In particular, the optimization module may be used to: determine a size metric for the hair; apply a first density curve to the size metric determined for the hair to generate a density multiplier value; and based upon the density multiplier value, determine whether the hair should be rendered.

Screen space optimization techniques for use in a hair/fur pipeline

A hair pipeline may be used to generate a user-selected geometry based upon a hair location for at least one hair with respect to a surface. A surface definition module may be used to define the surface. A display module may be used to: process a user-selected geometry and render the user-selected geometry at the hair location on the surface in place of the at least one hair.

Geometric instance techniques for use in a hair/fur pipeline

A system and process for digitally representing a plurality of surface-attached geometric objects on a model. The system and process comprises generating a plurality of particles and placing the plurality of particles on a surface of the model. A first plurality of curves are generated and placed at locations on the model. Characteristics are defined for the first plurality of curves. A second plurality of curves is interpolated from the first plurality of curves at locations of the particles. A plurality of surface-attached geometric objects is generated that replaces all of the particles and the second plurality of curves.
