graphene:with-frustums (vars &body body)

frustum1 ... frustumn -- newly created graphene:frustum-t instances
body -- a body that uses the bindings frustum1 ... frustumn

The graphene:with-frustums macro creates new variable bindings and executes the body that use these bindings. The macro performs the bindings sequentially, like the let* macro.

Each frustum can be initialized with values using the syntax for the graphene:with-frustum macro. See also the graphene:with-frustum documentation.
