API

TransformationMatrix

• apply(x,y,z,w) → [x, y, z, w]
  • Applies the transformation to a point or vector.
  • Returns the transformed point.
• concatenate(other) → TransformationMatrix4x4
  • Multiplies the two matrices.
  • Returns the product.
• set(row, column, value) → TransformationMatrix4x4
  • Modifies one element of this matrix.
  • Returns this.
• get(row, column) → number
  • Returns this value of one element.
• isEqual(other, tolerance) → boolean
  • Compares the two matrices.
  • Returns whether the matrices are equal.
• copy(overrides: {e11? ... e44?}) → TransformationMatrix4x4
  • Returns a copy.
• toString(digits?) → string
  • Returns the string representation.

Operations

• zero() → TransformationMatrix4x4
  • Returns a matrix with all elements set to 0.
• identity() → TransformationMatrix4x4
  • Returns the identity matrix.
• translation(x,y,z) → TransformationMatrix4x4
  • Returns a translation matrix.
• scale(x,y,z)→ TransformationMatrix4x4
  • Returns a scaling matrix.
• rotateX(angle)→ TransformationMatrix4x4
  • Returns a rotation matrix around the x-axis.
• rotateY(angle)→ TransformationMatrix4x4
  • Returns a rotation matrix around the y-axis.
• rotateZ(angle)→ TransformationMatrix4x4
  • Returns a rotation matrix around the z-axis.
