Renderbuffer¶

class moderngl.Renderbuffer¶

Renderbuffer objects are OpenGL objects that contain images. They are created and used specifically with Framebuffer objects. They are optimized for use as render targets, while Texture objects may not be, and are the logical choice when you do not need to sample from the produced image. If you need to resample, use Textures instead. Renderbuffer objects also natively accommodate multisampling.

A Renderbuffer object cannot be instantiated directly, it requires a context. Use Context.renderbuffer() or Context.depth_renderbuffer() to create one.

Create¶

Context.renderbuffer(size, components=4, samples=0, dtype='f1') → Renderbuffer

Renderbuffer objects are OpenGL objects that contain images. They are created and used specifically with Framebuffer objects.

Keyword Arguments:
Parameters:	size (tuple) – The width and height of the renderbuffer. components (int) – The number of components 1, 2, 3 or 4.
	samples (int) – The number of samples. Value 0 means no multisample format. dtype (str) – Data type.
Returns:	`Renderbuffer` object

Context.depth_renderbuffer(size, samples=0) → Renderbuffer

Renderbuffer objects are OpenGL objects that contain images. They are created and used specifically with Framebuffer objects.

Keyword Arguments:
Parameters:	size (tuple) – The width and height of the renderbuffer.
	samples (int) – The number of samples. Value 0 means no multisample format.
Returns:	`Renderbuffer` object
