Constructor Detail

def self.create(context, count : Int) : self #

Creates multiple new buffers.

The number of buffers to create is given by count. Unlike .generate, resources are created in advance instead of on the first binding.

  • OpenGL function: glCreateBuffers
  • OpenGL version: 4.5

def self.generate(context, count : Int) : self #

Generates multiple new buffers.

This ensures unique names for the buffer objects. Resources are not allocated for the buffers until they are bound.

See: .create

  • OpenGL function: glGenBuffers
  • OpenGL version: 2.0

def self.new(context : Context, names : Slice(Object::Name)) #

Creates a list of objects from the same context with their names.

def self.new(context : Context, names : Enumerable(Object::Name)) #

Creates a list of objects from the same context with their names.


[View source]
def self.new(context : Context, objects : Enumerable(T)) #

Creates a list of object from the same context.


[View source]
def self.new(context : Context, size : Int, &) #

Creates a list of objects from the same context.

Yields a pointer to a block of memory to populate with object names.
