Howto add colors and shape in nbody.jl test example about glvisualize.jl HOT 6 CLOSED

Hi,
off the top of my head, something like this should work:

visualize(positions, primitive=GLNormalMesh(your_custom_mesh),
particle_color=rgba(1,0,1,1))

You can look at the results of GLVisualize.visualize_default(positions, Style{}()) (I need to give this a nicer interface and export it), to see
what defaults it uses ( to then give it customized attributes).

You might want to create something like call{M <: Mesh}(::Type{M}, Sphere) = M(sphere_vertex, sphere_faces)

I'll hope to finish my bachelor thesis in the next days... After that I'll
use 100% of my time to develop the edit widgets ;)

Best,
Simon

Hi Simon,

I am wondering how I can have different specified colors and/or shapes for
the planets in example
nbody.jl.

In the variant that I use (subscreen6.xml) of Romeo/test, the code says

const positions     = lift(send_frame, time_i, Input(world.planets))
const robj          = visualize(positions, model=scalematrix(Vec3(0.1f0)),
                                screen=sc, camera=cam)

Best
Alain

PS: please let me know when I can try the edit object.

Hi

I understand you are busy, so I will not bug you for a fortnight.

I'll try to use your suggestions. The problem is that in this example there are 4 planets, so I suppose I need to separate them and issue separate visualize for each (with proper color and style), in the same spirit as what is done to display the trajectories.

Okay, try it out... you need to update GLAbstraction and GLVisualize.
(Example in test_particles.jl)

Hi Simon,

got it to run, also needed to update Reactive. I'll let you write your thesis from now on.

PS: FYI, I made some progress with extending MetadataTools to display installed packages
https://github.com/AlainLich/MetadataTools.jl/tree/supportInstalled. For Romeo (including GLAbstraction), this gives the following graph

(This needs several patches notably to Graphs, corresponding PRs not merged yet)
