Apologies for duplication, as this request has been made before, here and here . In each case the thread drifted off topic, so I’m hoping to recenter the discussion. It would be very useful to construct a RhinoCommon Texture object from a memory stream rather than a file path. (FileName and FileRefe…

Did you try using my in-memory texture sample from the thread you linked to? It should serve as a good example of how you can approach this. Instead of the Bitmap object you’d use your stream. The evaluator you’d adapt to work with it. Don’t forget to change any GUID

Thanks @nathanletwory , I did see your post. But per question (3) above, I’m looking for a way to draw directly in a display conduit (the meshes in question are not doc objects). As I understand it, RenderMaterials cannot be applied to DisplayPipeline meshes, or am I missing something?

Ok, I didn’t realize you want to use only display conduit. For that I hope @stevebaer can help more, as I am not familiar with DisplayMaterials

To make this more concrete, I’ve created a lightweight C# PlugIn that illustrates what I’m trying to do – and highlights the issues raised in question (4). As a placeholder for the progressive falsecolor pipeline, the project includes a “BitmapTexture” command that repeatedly re-textures a bunch of …

We don’t really have a good mechanism for setting bitmap textures with anything other than file paths. It sounds like the first thing we need to figure out is if there is a bug in the texture cache as that seems to be what is happening if reusing paths is unpredictably updating. @DavidEranen can yo…

@sarg Thanks for reporting and for the example project. So far I’ve created two YouTrack items based on my testing: https://mcneel.myjetbrains.com/youtrack/issue/RH-59415 (Deleting a texture file from disk will cause a slowdown in the resource manager) https://mcneel.myjetbrains.com/youtrack/issue…

Thanks @DavidEranen . I’ll stay tuned. In the meantime I suppose I can play with map-compositing to reduce the number of files, since I don’t need the textures to wrap.

@stevebaer and @DavidEranen , would it be possible to add a property for the DisplayMaterial (for use in conduits only) which accepts a System.Drawing.Bitmap which only exists in memory but not physically ? I think this is the initial request of this and the two threads linked above. _ c.

Hi Clement, We don’t have a good system for this yet. I request makes sense and I can understand the need, but the texture caching mechanism at the moment doesn’t allow for this. We could let you set a System.Drawing.Bitmap on a material, but before we have a new architecture in place we would need…
