index

• identity (num[4][4]):  – The identity Matrix.
• rotate (opdef):  – Create a 3d rotation matrix from an axis and angle
• scale (opdef):  – Create a 3d scale matrix.
• translate (opdef):  – Create a 3d translation matrix.

details

• identity (num[4][4]):  – The identity Matrix.
• rotate (opdef):  – Create a 3d rotation matrix from an axis and angle

  (mat4/translate axis angle)

  This is a pure op.

  axis is a num[3] array representing a unit vector.

• scale (opdef):  – Create a 3d scale matrix.

  (mat4/scale scale) (mat4/scale x y z)

  This is a pure op.

  scale can be a single number for uniform scaling, or an array of three numbers that will be used like x, y and z.

• translate (opdef):  – Create a 3d translation matrix.

  (mat4/translate vec) (mat4/translate x y z)

  This is a pure op.

  vec is a num[3] array.

• yaw-pitch-roll (opdef):  – Create a 3d rotation matrix from euler angles.

  (yaw-pitch-roll vec3) (yaw-pitch-roll y p r)

  This is a pure op.
