Implementations§

source§

impl Matrix

source

pub fn decompose(&self) -> Option<(Vec3, Vec3, Quaternion, Vec3, Vec4)>

Decomposes a transformation matrix into its component transformations.

The algorithm for decomposing a matrix is taken from the CSS3 Transforms specification; specifically, the decomposition code is based on the equivalent code published in “Graphics Gems II”, edited by Jim Arvo, and available online.

Returns

true if the matrix could be decomposed

translate

the translation vector

scale

the scale vector

rotate

the rotation quaternion

shear

the shear vector

source

pub fn equal_fast(&self, b: &Matrix) -> bool

Checks whether the two given Matrix matrices are byte-by-byte equal.

While this function is faster than graphene_matrix_equal(), it can also return false negatives, so it should be used in conjuction with either graphene_matrix_equal() or near(). For instance:

⚠️ The following code is in C ⚠️

  if (graphene_matrix_equal_fast (a, b))
    {
      // matrices are definitely the same
    }
  else
    {
      if (graphene_matrix_equal (a, b))
        // matrices contain the same values within an epsilon of FLT_EPSILON
      else if (graphene_matrix_near (a, b, 0.0001))
        // matrices contain the same values within an epsilon of 0.0001
      else
        // matrices are not equal

pub fn new_look_at(eye: &Vec3, center: &Vec3, up: &Vec3) -> Self

Initializes a Matrix so that it positions the “camera” at the given eye coordinates towards an object at the center coordinates. The top of the camera is aligned to the direction of the up vector.

Before the transform, the camera is assumed to be placed at the origin, looking towards the negative Z axis, with the top side of the camera facing in the direction of the Y axis and the right side in the direction of the X axis.

In theory, one could use self to transform a model of such a camera into world-space. However, it is more common to use the inverse of self to transform another object from world coordinates to the view coordinates of the camera. Typically you would then apply the camera projection transform to get from view to screen coordinates.
