compose cljs

(compose position euler-or-quaternion scale)

Sets this matrix to the transformation composed of position, quaternion and scale.

from-col-seq cljs

(from-col-seq sq)

Sets the elements of this matrix based on an array in column-major format.

from-row-seq cljs

(from-row-seq sq)

Set the elements of this matrix to the supplied row-major values n11, n12, ... n44.

identity-matrix4 cljs

(identity-matrix4)

Resets this matrix to the identity matrix.

IMatrix4 cljs protocol

invert cljs

(invert m)

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.

decompose cljs

(decompose m)

Decomposes this matrix into it's position, quaternion and scale components.

set-position cljs

(set-position m v)

Sets the position component for this matrix from vector v, without affecting the rest of the matrix - i.e. if the matrix is currently:

scale cljs

(scale m v)

Multiplies the columns of this matrix by vector v.

extract-rotation cljs

(extract-rotation m)

Extracts the rotation component of the supplied matrix m into this matrix's rotation component.

transpose cljs

(transpose m1)

Transposes this matrix.

almost-equals cljs

(almost-equals m1 m2)

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

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.

clone' cljs

(clone' m)

Creates a new Matrix4 and with identical elements to this one.

translate cljs

(translate m v)

Sets the position component for this matrix from vector v,

multiply cljs

(multiply m1 m2)

Sets this matrix to m1 * m2.

make-basis cljs

(make-basis x-axis y-axis z-axis)

Set this to the basis matrix consisting of the three provided basis vectors: xAxis.x, yAxis.x, zAxis.x, 0, xAxis.y, yAxis.y, zAxis.y, 0, xAxis.z, yAxis.z, zAxis.z, 0, 0, 0, 0, 1

make-rotation-axis cljs

(make-rotation-axis axis theta)

axis — Rotation axis, should be normalized. theta — Rotation angle in radians.

make-rotation-from-euler cljs

(make-rotation-from-euler e)

Sets the rotation component (the upper left 3x3 matrix) of this matrix to the rotation specified by the given Euler Angle. The rest of the matrix is set to the identity. Depending on the order of the euler, there are six possible outcomes. See this page for a complete list.

make-rotation-from-quaternion cljs

(make-rotation-from-quaternion q)

Sets the rotation component of this matrix to the rotation specified by q, as outlined here. The rest of the matrix is set to the identity. So, given q = w + xi + yj + zk, the resulting matrix will be: 1-2y²-2z² 2xy-2zw 2xz+2yw 0 2xy+2zw 1-2x²-2z² 2yz-2xw 0 2xz-2yw 2yz+2xw 1-2x²-2y² 0 0 0 0 1

make-rotation-x cljs

(make-rotation-x theta)

theta — Rotation angle in radians.

Sets this matrix as a rotational transformation around the X axis by theta (θ) radians. The resulting matrix will be: 1 0 0 0 0 cos(θ) -sin(θ) 0 0 sin(θ) cos(θ) 0 0 0 0 1

make-rotation-y cljs

(make-rotation-y theta)

theta — Rotation angle in radians.

Sets this matrix as a rotational transformation around the Y axis by theta (θ) radians. The resulting matrix will be: cos(θ) 0 sin(θ) 0 0 1 0 0 -sin(θ) 0 cos(θ) 0 0 0 0 1

make-rotation-z cljs

(make-rotation-z theta)

theta — Rotation angle in radians.

Sets this matrix as a rotational transformation around the Z axis by theta (θ) radians. The resulting matrix will be: cos(θ) -sin(θ) 0 0 sin(θ) cos(θ) 0 0 0 0 1 0 0 0 0 1

make-scale cljs

(make-scale x y z)

x - the amount to scale in the X axis. y - the amount to scale in the Y axis. z - the amount to scale in the Z axis.

Sets this matrix as scale transform: x, 0, 0, 0, 0, y, 0, 0, 0, 0, z, 0, 0, 0, 0, 1

make-shear cljs

(make-shear x y z)

xy - the amount to shear X by Y. xz - the amount to shear X by Z. yx - the amount to shear Y by X. yz - the amount to shear Y by Z. zx - the amount to shear Z by X. zy - the amount to shear Z by Y.

Sets this matrix as a shear transform: 1, yx, zx, 0, xy, 1, zy, 0, xz, yz, 1, 0, 0, 0, 0, 1

make-translation cljs
