Matrix Operations

The Matrix namespace includes functions for creating and manipulating matrices.

  • zeros(): Returns a 4x4 matrix filled with zeros.
  • multiplyVector(m, i): Multiplies a matrix by a vector.
  • makeIdentity(): Creates an identity matrix.
  • makeRotationX(angleRad): Creates a rotation matrix around the X-axis.
  • makeRotationY(angleRad): Creates a rotation matrix around the Y-axis.
  • makeRotationZ(angleRad): Creates a rotation matrix around the Z-axis.
  • makeTranslation(x, y, z): Creates a translation matrix.
  • makeProjection(m, fov, aspectRatio, near, far): Creates a projection matrix.
  • multiplyMatrix(m1, m2): Multiplies two matrices.
  • lookAt(pos, target, up): Creates a lookAt matrix.
  • quickInverse(m): Calculates the quick inverse of a matrix, optimized for rotation/translation matrices.

Utility Functions

  • transpose(m): Transposes a matrix.
