Sorry, I haven't updated GLAbstraction for 1.0 yet - do you need GLAbstraction directly, or does E.g. Makie work for you? Makie includes a copy of GLAbstraction with 1.0 compat!

I looked at Makie, I'm just getting lost in where a lot of the GL low level stuff is. All I need to do is create a GL context and a few easy shaders. My project requires me to render a ton of cubes and it seems as though the way Makie sends data through is as a 1D texture. For example, if I try this in Makie

lottaCubes = [(HyperRectangle(Vec3f0(rand(1:100),rand(1:100),rand(1:100)),Vec3f0(1)),
                RGBAf0(rand(Float32),rand(Float32),rand(Float32),1)) for i = 1:16385]

meshes = map(GLNormalMesh, lottaCubes)
mesh(merge(meshes))

I get a glTexImage 1D width error as the maximum size for a 1D texture is 16384.

It would seem then that I need to write some basic shaders and add some occlusion culling or something to be able to render more.

[SimonDanisch]

This works for me:

using Makie
N = 16385
positions = [rand(Vec3f0) .* 100 .+ 1 for i = 1:16385]
colors = [RGBAf0(rand(Float32), rand(Float32), rand(Float32), 1) for i = 1:16385]
meshscatter(positions, color = colors, marker = FRect3D(Vec3f0(0), Vec3f0(2)), show_axis = false)

Interesting, I will investigate further. I am still very new to Julia, I am coming from doing GL work in Common Lisp. Thank you for your help.

Hi, this is a tough issue for me as well. Except, I use the vertex and fragment shader macros which aren't accommodated in Makie as far as I know...

[SimonDanisch]

They are ;) GLMakie contains a full copy of GLAbstraction: https://github.com/JuliaPlots/GLMakie.jl/blob/master/src/GLAbstraction/GLShader.jl#L2

[nfehrenbach]

Since GLMakie contains a functional 1.0 version of GLAbstraction, are there plans to update GLAbstraction or has all development moved over to GLMakie?

[SimonDanisch]

I kind of gave GLAbstraction to @louisponet who updated things... I'm currently work on ShaderAbstractions.jl, which might become the new GLAbstraction from my perspective ;)

[louisponet]

I have been using the master version of this repo in projects of mine, that should work perfectly on Julia 1.x. Could you try ] add GLAbstraction#master? I guess I should make a release.

On the development side of things, I work on OpenGL projects off and on, and I use this for all lowish-level OpenGL functionality. I add/update things as I use them since to me it doesn't make a lot of sense to create/develop an API type package without actually using it. Therefore, I'm fully open to any help, issues and suggestions on where to take this package.

[nfehrenbach]

I'm away from my machine today, but I'll try this evening and reply with my results.

@louisponet , your solution to add the master branch did the trick! Thanks!
