Package: graphene
Macro graphene:with-point3ds
Lambda Listgraphene:with-point3ds (vars &body body) SyntaxArgumentsDetails The graphene:with-point3ds macro creates new variable bindings and
executes the body that use these bindings. The macro performs the bindings sequentially, like the let* macro. Each point can be initialized with values using the syntax for the graphene:with-point3d macro. See also the graphene:with-point3d documentation. Examples(graphene:with-point3ds (p1 (p2 1.2 1.3 1.4) (p3 p2)) (list (list (graphene:point3d-x p1) (graphene:point3d-y p1) (graphene:point3d-z p1)) (list (graphene:point3d-x p2) (graphene:point3d-y p2) (graphene:point3d-z p2)) (list (graphene:point3d-x p3) (graphene:point3d-y p3) (graphene:point3d-z p3)))) => ((0.0 0.0 0.0) (1.2 1.3 1.4) (1.2 1.3 1.4)) | See also |
