Hi, I am struggeling to display points with a very precise coordinates while using GL Shader for Grasshopper. Do I need to implement the WorldToScreen built-in function to display the points with the precise coordinates or what are the options while using GL Shader? Any suggestions @stevebaer pleas…

The gh file that you posted is just 50000+ vertices being sent into a very simple shader. I’m having trouble understanding what you are trying to do. Could you explain a bit more what the problem is that you are trying to solve?

Hi @stevebaer , thank you for your reply. I am able to display the vertices with the Symbol Display component. However if I try to display the vertices with the GL Shader it does not work (probably because of the precision of the coordinates). My question is how to edit the GL Shader code to be abl…

You have a list of 62788 identical points :interrobang: What is your point?

@Joseph_Oster the points are not identical even it appears to be so due the formating of decimals in Grasshopper. The points are actualy very precise and if you scale them up and use Crete Set component you will see 62788 unique points with precise coordinates.

[image] Matouš Stieber: the points are not identical even it appears to be so due the formating of decimals in Grasshopper. They certainly do appear to be identical. CullPt (Cull Duplicates) does not differentiate them until the ‘Tolerance’ (T) value is 1.0e-9 or smaller (0.000000001). Agai…

[image] Joseph_Oster: Again, what is your point? To display the vetices with the GL Shader component identically as it is possible with the Symbol Display component.

I still don’t see the point? Just multiply the points by 100000000000: (or whatever) [GL Shader precise point coordinates] Of course, I haven’t bothered to download the plugin… :roll_eyes: [missing]

@Joseph_Oster are you genuinely trying to solve the issue I am having or just label my question as irrelevant? My aim is display the vetices with the GL Shader because the component is much more memory efficient than the Symbol Display component. I am usually working with multiple millions of verti…

[image] Matouš Stieber: are you genuinely trying to solve the issue I am having Solve, no. Understand, yes. Maybe I need to get the ‘ghgl’ plugin because so far, I still don’t understand. What display device are you using that shows more that ~8 million pixels (3840 X 2160)? What sort of …

You are most likely pushing the limits of what floating precision numbers can handle. I suggest you scale the verts and move them to origin. Then everything works as expected: [image] GL Shader precise point coordinates.gh (576.9 KB)
