4 Definitions

Definitions are sorted by export status, category, package, and then by lexicographic order.

4.1.2 Functions

Function: expand-glsl-type TYPE &key DEFAULT

Package

glsl-packing

Source

base-types.lisp (file)

Function: expand-glsl-types SLOTS

Expand glsl types like :vec4 to style expected by pack-structs in list of slot definitions. Types of the form (TYPE X) are treated as arrays, with dimension X, where * or :* means unspecified size.

Package

Source

base-types.lisp (file)

Function: pack-structs TYPES &key ROOTS DUMP-BASE-TYPES

TYPES is a list of lists (NAME TYPE) which is processed like a sequence of calls to PACK-STRUCT, except with the ability to refer to previous types by name. if NAME is :packing or :major, TYPE is interpreted as new default value for corresponding arguments to PACK-STRUCT for following definitions. If ROOTS is specified, it should be a list of block names to use as roots when removing unused types from output. If DUMP-BASE-TYPES is true, output will include data for used scalar/vec/mat types types.
