inverse :: (Coercible Mat4 a, Coercible Mat4 a) => a -> a Source #
Compute an inverse matrix, slowly.
apply :: Vec3 -> Transform -> Vec3 Source #
Apply transformation to a vector, then normalize with perspective division
(!.) :: Transform -> Vec3 -> Vec3 infixr 5 Source #
Matrix - row vector multiplication with perspective division
vOut = pv <> translate !. vIn
translateV :: Vec3 -> Transform Source #
rotateX :: Float -> Transform Source #
Clockwise rotation around positive X axis.
Matches a -> rotateQ (axisAngle (vec3 1 0 0) a).
rotateY :: Float -> Transform Source #
Clockwise rotation around positive Y axis.
Matches a -> rotateQ (axisAngle (vec3 0 1 0) a).
rotateZ :: Float -> Transform Source #
Clockwise rotation around positive Z axis.
Can be used for 2D rotation in the XY plane.
Matches a -> rotateQ (axisAngle (vec3 0 0 1) a).
In the right-handed "window coordinates" (e.g. top-left corner is 0,0) "right" becomes "down" after 90deg turn.
rotateQ :: Quaternion -> Transform Source #
