CamTools v0.1.6 Release Notes

Summary

Terminology Clarification: Previously, the terms "depth" (z-depth) and "distance" (Euclidean distance between a 3D point and the camera center) were used interchangeably, leading to confusion. This release clarifies and standardizes the terminology to avoid ambiguity.
Function Signatures: Use im_depth or im_distance in function signatures to refer to depth images or distance images, respectively.
Conversion Functions: Added conversion functions between distance image and depth image: ct.convert.im_distance_to_im_depth and ct.convert.im_depth_to_im_distance.

Now, some functions are annotated with e.g., points: Float[np.ndarray, "n 3"] to provide better syntax.
Full type annotation is planned in the future, along with a documentation website.
Previously we considered adding a flexible backend with ivy in this release, but it was canceled for simplicity.

Issue: A segmentation fault occurs when using certain versions of Open3D with numpy 2.x. This issue is documented in Open3D issue #6840.
Temporary Fix: This release restricts the use of numpy 1.x to avoid the segfault. This restriction will likely be removed in future releases when Open3D 0.19 is released, as per this comment.
