Textures on PointGeometry3D object about helix-toolkit

[holance]

It's not supported at this moment. If you don't need real-time texture update, you can manually sample colors from the picture and apply point color onto existing PointGeometry3D.

I understand that it's a complicated process of manually sampling colors from the picture and apply point color onto existing PointGeometry. But could please give me a brief example of how to take color from pictures and compare it to exact needed point in pointGeometry

Hello,

I'm currently engaged in a project where I'm working with PointGeometryModel3D within HelixToolkit (SharpDX) for WPF, displaying it with individual color information for each point. This point cloud is generated using the Intel RealSense SDK in C#. Given the limitations around directly overlaying a texture on a point cloud in HelixToolkit.SharpDX, I'm exploring alternative routes to achieve a similar visual effect.

To this end, I have a couple of inquiries:

I am keen to learn if there have been any recent developments or insights into converting a point cloud (PointGeometryModel3D) into a mesh geometry. The rationale here is that working with mesh geometries might simplify the process of texturing since meshes handle textures in a more straightforward manner.
I am also looking for any known methods, techniques, or tools within HelixToolkit.SharpDX or external utilities that could aid in this conversion process, specifically from point clouds generated with the Intel RealSense SDK in C# to mesh geometries.

Understanding that direct texturing of point clouds might not be feasible due to the inherent lack of surface information for texture mapping, converting the point cloud to a mesh could present a viable solution. If anyone has experience with such a process, especially in the context of using point clouds generated by the Intel RealSense SDK, or knows of algorithms or tools that integrate well with HelixToolkit.SharpDX for these purposes, I would greatly appreciate your insights.

Thank you in advance for any guidance or suggestions you might have.

Best regards from Germany,
Oliver
