from-matrix4 cljs

(from-matrix4 m4)

Set this matrix to the upper 3x3 matrix of the Matrix4 m.

get-normal-matrix cljs

(get-normal-matrix m4)

m - Matrix4 Sets this matrix as the upper left 3x3 of the normal matrix of the passed matrix4. The normal matrix is the inverse transpose of the matrix m.

identity-matrix3 cljs

(identity-matrix3)

Resets this matrix to the 3x3 identity matrix: 1, 0, 0 0, 1, 0 0, 0, 1

IMatrix3 cljs protocol

almost-equals cljs

(almost-equals m1 m2)

Return true if this matrix and m are almost equal. every element is less than 0.000001.

clone' cljs

(clone' m)

Creates a new Matrix3 and with identical elements to this one.

determinant cljs

(determinant m)

Computes and returns the determinant of this matrix.

equals cljs

(equals m1 m2)

Return true if this matrix and m are equal.

invert cljs

(invert m1)

Inverts this matrix, using the analytic method. You can not invert with a determinant of zero. If you attempt this, the method produces a zero matrix instead.

multiply cljs

(multiply m1 m2)

Sets this matrix to m1 * m2.

transpose cljs

(transpose m1)

Transposes this matrix in place.

matrix3 cljs

(matrix3)

(matrix3 sq)

Constructor Matrix3() Creates and initializes the Matrix3 to the 3x3 identity matrix.
