Octree is in normalized [-1,1] world coordinate frame 'rays_o': ray origin in normalized world coordinate system 'rays_d': (N,3) unit

Reserves space to store at least *capacity* elements. */

Prepares inputs and applies network 'fn'. @inputs: (N_ray,N_sample,3) sampled points on rays in GL camera's frame @viewdirs: (N_ray,3) unit le

Returns the size of this buffer. */

Tries increasing the buffer capacity to *new_capacity*. It can increase the capacity by a smaller amount than requested but guarantees there is space

Computes 128-bit result of multiplication of two 64-bit unsigned integers.

Computes upper 64 bits of multiplication of two 64-bit unsigned integers.

Run all_gather on arbitrary picklable data (not necessarily tensors). Args: data: any picklable object group: a torch proces

DEPRECATED!

Assigns pow(10, exp) to this bigint.

color stuff

Returns a pointer to the buffer data. */

Divides this bignum by divisor, assigning the remainder to this and returning the quotient.

Run gather on arbitrary picklable data (not necessarily tensors). Args: data: any picklable object dst (int): destination ra

* @brief Find the transformation that rotates the image while ensuring the rotated image pixels are all within bound * * @param H * @param W * @pa

Returns a cached power of 10 `c_k = c_k.f * pow(2, c_k.e)` such that its (binary) exponent satisfies `min_exponent <= c_k.e <= min_exponent + 28`.

@pose_offset: optimized delta pose of the first frame. Usually it's identity

Pop item from front. If there are no elements in the container, the behavior is undefined.

Render rays Args: H: int. Height of image in pixels. W: int. Width of image in pixels. K: float. Focal length of pinhole camera.

@near: (N_ray,1)

This is avoid msvc issue in sleep_for that happens if the clock changes. See https://github.com/gabime/spdlog/issues/609
