K3D-tools / K3D-jupyter

K3D lets you create 3D plots backed by WebGL with high-level API (surfaces, isosurfaces, voxels, mesh, cloud points, vtk objects, volume renderer, colormaps, etc). The primary aim of K3D-jupyter is to be easy for use as stand alone package like matplotlib, but also to allow interoperation with existing libraries as VTK.

k3d.points slow with shade='mesh' #334

Closed marcinofulus closed 2 years ago

marcinofulus commented 2 years ago

k3d.points(np.random.randn(1000,3),point_size=0.1,shader='mesh') renders with fps<1

Hi @marcinofulus

Can you provide a little bit more information about your platform? Please open k3d plot and check developer console and copy a lines like that:

K3D: (UNMASKED_VENDOR_WEBGL) Google Inc. (NVIDIA)
Renderer.js:138 K3D: (UNMASKED_RENDERER_WEBGL) ANGLE (NVIDIA, NVIDIA GeForce GTX 1070 Direct3D11 vs_5_0 ps_5_0, D3D11-30.0.14.9613)
Renderer.js:139 K3D: (depth bits) 24
Renderer.js:140 K3D: (stencil bits) 8

I checked your code and I have 60 fps. But please look closer to parameter:

        mesh_detail: `int`.
            Default is 2. Setting this to a value greater than 0 adds more vertices making it no longer an
            icosahedron. When detail is greater than 1, it's effectively a sphere. Only valid if shader='mesh'

Best regards,

I tried other browser - in firefox it works as it used to work - it looks like a google-chrome regression after some upgrade....
