dmat2

dmat2(c0: DVec2, c1: DVec2) -> DMat2
dmat2(diagonal: Double) -> DMat2

A matrix of doubles from its columns, or with one value down the diagonal; m[i] is a column, m * v applies it.

dmat3

dmat3(c0: DVec3, c1: DVec3, c2: DVec3) -> DMat3
dmat3(diagonal: Double) -> DMat3

A matrix of doubles from its columns, or with one value down the diagonal; m[i] is a column, m * v applies it.

dmat4

dmat4(c0: DVec4, c1: DVec4, c2: DVec4, c3: DVec4) -> DMat4
dmat4(diagonal: Double) -> DMat4

A matrix of doubles from its columns, or with one value down the diagonal; m[i] is a column, m * v applies it.

dvec2

dvec2(x: Double, y: Double) -> DVec2

A vector of doubles from components or shorter vectors, any number widened; a written number is taken exact, so dvec2(0.1, 0.2) holds the doubles nearest a tenth and a fifth.

dvec3

dvec3(x: Double, y: Double, z: Double) -> DVec3
dvec3(xy: DVec2, z: Double) -> DVec3
dvec3(v: Vec3) -> DVec3

A vector of doubles from components or shorter vectors, any number widened; a written number is taken exact.

dvec4

dvec4(x: Double, y: Double, z: Double, w: Double) -> DVec4
dvec4(xyz: DVec3, w: Double) -> DVec4
dvec4(v: Vec4) -> DVec4

A vector of doubles from components or shorter vectors, any number widened; a written number is taken exact.

ivec2

ivec2(x: Int, y: Int) -> IVec2

ivec3

ivec3(x: Int, y: Int, z: Int) -> IVec3
ivec3(xy: IVec2, z: Int) -> IVec3
ivec3(x: Int, yz: IVec2) -> IVec3

An integer vector from components or a shorter integer vector: a cell, an offset; at and put take one as an address.

ivec4(xyz: IVec3, w: Int) -> IVec4
ivec4(xy: IVec2, zw: IVec2) -> IVec4

An integer vector from components or shorter integer vectors, in order; v.wzyx and the like are swizzles.

lvec2

lvec2(x: Long, y: Long) -> LVec2
lvec2(v: IVec2) -> LVec2

A vector of longs from components or shorter integer vectors, an Int widened.

lvec3

lvec3(x: Long, y: Long, z: Long) -> LVec3

mat2

mat2(c0: Vec2, c1: Vec2) -> Mat2
mat2(diagonal: Float) -> Mat2

mat3

mat3(c0: Vec3, c1: Vec3, c2: Vec3) -> Mat3
mat3(diagonal: Float) -> Mat3

A matrix from its columns, or with one value down the diagonal and zeros elsewhere; m[i] is a column, m * v applies it.

mat4(diagonal: Float) -> Mat4

A matrix from its columns, or with one value down the diagonal and zeros elsewhere; m[i] is a column, m * v applies it.

vec2

vec2(x: Float, y: Float) -> Vec2
