Returns the eigenvalues of the matrix. The eigenvalues are ordered, such that the first one is larger.

< Deletes the texture.

< Returns a vector with components sorted in descending order.

< Returns the diagonal of the matrix

Returns the scale portion of the transformation. The returned matrix is symmetric, but not necessarily diagonal, and it can include non-uniform scale.

< Transpose this matrix

< Returns a normalized copy of the quaternion.

< Multiply the transpose of this matrix with itself (i.e. this^T * this).

< Sets the quaternion as a rotation from one direction to another. The resulting quaternion is not normalized.

Sets the texture image using the given texture format, data format, and data type.

Sets a translation matrix with no rotation or scale

Sets the texture wrapping parameter. The acceptable values are GL_REPEAT, GL_MIRRORED_REPEAT, GL_CLAMP, and GL_CLAMP_TO_BORDER.

@name Set & Get value methods

Adds a diagonal matrix to this matrix and returns the result.

Builds mipmap levels for the texture. The texture image must be set first.

Returns the id of the item from the heap with the given heap position. Note that items that are removed from the heap appear in the inverse order with

Returns the id of the item at the top of the heap.

Returns if the matrix is diagonal.

Returns true if the node is a leaf node.

Moves the item with the given id towards the top of the heap. This method is useful for fixing the heap position after an item is modified externally

< returns the number of vertices

@name Normalize, Length, Conjugate, and Inverse functions

Returns a project matrix with field of view in radians

Removes and returns the item at the top of the heap. The removed item is not deleted, but it is removed from the heap by placing it right after the la

Sets the anisotropy level of the texture. The anisotropy value of 1 disables anisotropic filtering. Larger values provide provide better anisotropic f

< returns the bounding box of the node

Matrix representation of the cross product ( a x b)

Sets the data pointer of this class. This method is used for sharing the items array with other structures. Unlike setting the main data using the Mov

Sets anisotropic filtering to the maximum permissible value.

Turns off anisotropic filtering.

Set a project matrix with field of view in radians

Set a project matrix with the tangent of the half field of view (tan_fov_2)

Starts the timer

Returns the time passed since Start call in seconds. Note that this method does not actually stop the timer, it only returns the time passed since Sta

< Converts linear RGB to sRGB.

Adds a translation to the matrix

Adds a translation to the matrix

Attaches the given shader to the program. This function must be called before calling Link.

@name Constructors

< Returns true if the OpenGL texture object is not generated, i.e. the texture id is invalid.

< Returns true if the OpenGL program object is not generated, i.e. the program id is invalid.

< Returns the texture ID.

The Build method builds the heap structure using the main data. Therefore, the main data must be set using either CopyData, MoveData, or SetDataPointe

Builds a k-d tree for the given points. The positions are stored internally. The build is parallelized using Intel's Thread Building Library (TBB) or
