Cursor support in DirectX (C++)
MarcDub
✭✭
Is there any support/API to create the standard Cursor (dot / torus) in a DirectX/C++ application on the Hololens?
Also, is there any example, demo, or API to calculate the intersection of the gaze (user head direction) with the environment surface mesh? I know how to get gaze and surface mapping.

There's no API to create a cursor in DX. You'll be going down the path of creating vertexbuffers, indexbuffers, creating and setting shaders with their constant buffers, all the DX fun.
AFAIK there isn't a sample that shows how to do raycast against the mesh. The documentation alludes to passing the mesh to a physics system like Havok, but doesn't have a concrete example. In the past I've heard tales of success with Bullet physics, but I've not done this myself.

Thanks. I wanted to be sure before going down the rabbit hole.
Hi MarcDub,
have you found something? I want to do something similar.
@Khronossos : Yes, once you get the hand of creating a mesh in DX, it is pretty straightforward. Creating and displaying meshes in DX is not obvious though. I have moved to using Unity now so that it is not an issue anymore.
