Package: graphene
Macro graphene:with-sphere
Lambda Listgraphene:with-sphere ((var &rest args) &body body) SyntaxArgumentsDetails The graphene:with-sphere macro allocates a new graphene:sphere-t instance, initializes the sphere with the given
values and executes the body that uses the sphere.
After execution of the body the allocated memory for the sphere is released. When no argument is given the components of the sphere are initialized to zero. The initialization from another sphere is done with the graphene:sphere-init-from-sphere function. The initialization with a center and a radius uses the graphene:sphere-init function.
