BufferFloat¶

class BufferFloat¶

Bases: rumba.BufferConstFloat

A writable buffer for basic types like floats, integers, Imath::V3f, Imath::M44f..

The predefined Buffer types:

Constructors

__init__

Methods

`__getitem__`	operator[](i: int) -> reference
`__iter__`
`grow`(size)	Grow the buffer in order for it to be large enough for this size.
`resize`(size)	Resize the buffer.
`write`()	Return a writable accessor on the buffer data.

__getitem__()¶

operator[](i: int) -> reference

Returns the i-th array element.

This method is slower than using a buffer span

Parameters:	i (int) – The buffer element to access. Expect an access violation error if i is out of bounds.
Return type:	reference

grow(size: int) → None¶

Grow the buffer in order for it to be large enough for this size.

If the buffer is already large enough, does nothing.

Parameters:	size (int) – The minimal number of element the buffer must have

resize(size: int, d: T) → None¶

Resize the buffer.

The previous data are copied in the new buffer.

Parameters:	size (int) – The number of element. d (T) – The value to use to fill the new allocated elements.

write()¶

Return a writable accessor on the buffer data.

Use this buffer span for the best access performances.
