For issue #42 This is just some quick code I whipped up to get it working for my use case. It includes a traversal for the points, and it would...

More general queries

1

Would it be possible to add queries that are not tied to ray intersection tests? Something like can I provide a sphere and get a list of potential collisions to...

Camera pose vs Camera Matrix

1

I am trying to perform bundle adjustment in a problem where I know the location and rotation of the camera in world coordinate space(which I'll refer to as the pose...

How to scale an entire group of nodes?

1

I used `let mut g = window.add_group()` to create a `SceneNode`. Next, I added a bunch of spheres to this group using `let mut obj = g.add_sphere(10.0)`. Then I moved...

What is the correct way to mutate Mesh coords/faces? Currently, I have: ```rust use kiss3d::resource::Mesh; pub struct ClothViz { mesh: Rc, } ``` And a function where I update it:...

Compute hessian of grid?

4

I see operators to compute gradient, laplacian, etc. Is there any way to compute the hessian of a scalar grid in OpenVDB?

I am initializing a OpenVDB level set from another data structure, something like: ```cpp while(...) { idx = GetNextIndex(); pixel = GetNextPixel(); coord = openvdb::Coord(idx[0], idx[1], idx[2]); vdbAccessor.setValue(coord, pixels); }...

How to set camera intrinsics for edge?

5

For EdgeSE3ProjectXYZ, we can set the camera intrinsics with the public fx, fy, cx, cy values, in the [g2o codebase](https://github.com/RainerKuemmerle/g2o/blob/master/g2o/types/sba/types_six_dof_expmap.h#L228). How do I set these values in g2opy?

Are there any matrix-free solvers?

8

Hi! Does ndarray support any matrix-free solvers? In matrix-free solver, instead of `x = solve(A, b)`, we run `x = solve(f, b)`, where f is a function `f(y) = Ay`...

readSTL should check file header

#### Describe the bug I accidentally called readSTL on a .ply file. Totally my fault, but it'd be nice if the readSTL function had checked the header and made sure...
