I want to be able to colour walls in a revit model through the speckle viewer based on a certain property. This property could be many things and depending on the values would lead to the wall being hatched up left, up right, cross hatched or a solid colour. I have attached this photo to hopefully help explain.
I have got this working but this only completes one of the problems which is colour, I need to be able to apply a hatched texture too. I am struggling to find a solution in the docs, does anyone know of a way to do this?
I have a feeling I might need to upgrade my version of speckle viewer to 2.20^ (currently 2.5.5) to start playing with the new filter extension functions but this will require a bit of a re-write and would be great if that wasn’t the case.
Unfortunately, the docs page you are linking to is severely obsolete. You can find all up-to-date viewer documentation here.
Also, unfortunately, the viewer API does not currently allow you to add hatched texture (or otherwise) to objects. It is possible via a custom extension, but it will probably involve writing a shader.
Hatches have been in discussions for a while now, and there is a good chance we will introduce them one way or another at some point.
Ahh that’s unfortunate. Glad to hear they are in discussions, hopefully they will be introduced soon🤞
I have a limited knowledge of shaders but have enough knowledge that they are tricky so on the chance that I find myself with enough time to give it a go where would I start? Do I need to familiarise myself with 3JS?
Three.js knowledge would help since the viewer is built on top of three.js. However, there are plenty of other resource like the classic LearnWebGL since shaders are engine/framework agnostic.
