DVMat4 class final

A 4x4 matrix, column-major: element (row r, column c) is storage[c * 4 + r].

Constructors

DVMat4.compose(DVVec3 t, DVQuat r, DVVec3 s)

Translation * rotation * scale, the order glTF and the engine compose a node's local transform in.

factory

DVMat4.fromList(List<double> values)

Copies values (16 of them, column-major).

factory

DVMat4.identity()

factory

DVMat4.lookAt(DVVec3 eye, DVVec3 target, DVVec3 up)

A view matrix for an eye at eye looking at target.

factory

DVMat4.perspective(double fovYRadians, double aspect, double near, double far)

A right-handed perspective projection into OpenGL clip space (NDC z in -1..1). fovYRadians is the full vertical field of view.

factory

DVMat4.scaling(DVVec3 s)

factory

DVMat4.translation(DVVec3 t)

factory

Properties

determinant3 → double

The determinant of the upper 3x3, whose sign says whether this matrix mirrors.

hashCode → int

The hash code for this object.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

storage → Float64List

final

translation → DVVec3

no setter

Methods

inverse() → DVMat4?

The inverse, or null when this matrix has none.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

transformDirection(DVVec3 d) → DVVec3

d as a direction: rotated and scaled, never translated.

transformPoint(DVVec3 p) → DVVec3

p as a point: translated, and divided by w when this is a projection.

Operators

operator *(DVMat4 other) → DVMat4

operator ==(Object other) → bool

The equality operator.
