< Evaluates the polynomial at `x`.

Fills the given direction array with normalized directions using the points array. Call this function if you need strand directions for shading. The g

< Finds all roots of the polynomial and returns the number of roots found.

Fixes the alpha values of an image with the given width and height using the specified method. If the image will be used with alpha-to-coverage, the s

Fixes the alpha values of an RGBA image with the given width and height using the specified method. Only the alpha channel of the image is modified, t

Fixes the alpha values of all mipmap levels of an OpenGL texture, starting with the given level. If the texture does not contain semi-transparent regi

Fixes the alpha values of all mipmap levels of an OpenGL texture, starting with the given level. If the texture does not contain semi-transparent regi

Fixes the alpha values of a mipmap level of an OpenGL texture. If the image will be used with alpha-to-coverage, the spp parameter should indicate the

< Returns true if the polynomial has a root.

Constructor can register the callback, but only if the OpenGL context is created before the constructor is called. If the regsiterCallback argument is

< Returns true if all components are finite real numbers.

< Returns true if all components are finite real numbers.

< Returns true if all components are finite real numbers.

Returns the average of all recorded times (max previous 128 records)

Returns the average scale factor

Returns the average scale factor

Returns the average scale factor of the 3 by 3 sub-matrix

Returns the average scale factor of the 3 by 3 sub-matrix

< Returns the minimum values of the bounding box

< Returns true if the bounding box has been computed.

< Returns the number of levels in the hierarchy.

Returns the child nodes of the given node (parent must be an internal node).

Returns the closest point to the given position within the given radius. It returns true, if a point is found.

Returns the closest point distance squared to the given position within the given radius. It returns true, if a point is found.

Returns the closest point index to the given position within the given radius. It returns true, if a point is found.

Returns the closest point position to the given position within the given radius. It returns true, if a point is found.

< Returns transparency array (transparency at each hair point).

< Returns a row of the matrix

< Returns a row of the matrix

< Returns a row of the matrix

Returns the eigenvalues and sets the given vectors as the eigenvectors of the matrix. The eigenvalues are ordered, such that the first one is larger.

Returns the id of the child node with the given index (parent must be an internal node). The child index can only be 0 or 1, since this is a binary BV

< Reduces the rotation of the quaternion by half.

< Reduces the rotation of the quaternion by half.

< Deletes the render buffer.

< Deletes the shader.

< Deletes the program.

Returns the last measured time. If no time is measured before, returns zero.

< Returns the i^th light position at the given level. Note that this is not the position of the light with index i.

< Returns the material index of the face. This method goes through material counts of all materials to find the material index of the face. Returns a

< Returns the number of faces associated with the given material ID.

< Returns a matrix representing the rotation of the quaternion.

< Returns a matrix representing the rotation and scale of the quaternion.

< Returns a matrix representing the rotation of the quaternion.

Returns the maximum measured time

Returns the maximum possible Poisson disk radius in the given dimensions for the given sampleCount to spread over the given domainSize. If the domainS

Returns the minimum measured time

Returns the bounding box of the node as 6 float values. The first 3 values are the minimum x, y, and z coordinates and the last 3 values are the maxim

Returns the number of elements inside the given node (must be a leaf node).
