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.

A fixed view #381

Closed Depth2World closed 1 year ago

Depth2World commented 1 year ago

Hi there, Appreciate your brilliant work! Now, I want to plot a 3d volume. How can I have an fixed view when I run the code?

renefritze commented 1 year ago

Plot instances have attributes to achieve what you want.

Plot().camera_no_pan = True
Plot().camera_no_rotate = True
Plot().camera_no_zoom = True
Depth2World commented 1 year ago

Yes, I found that. The attributes are boolean. I mean that I need a special view for showing the volume. How can I fix the view?

RossBencina commented 1 year ago

I think you mean "specific view" not "special view" -- very different!

You can set the camera matrix. For example, for a top down view I have:

cameraMatrix_= [
              xc, yc, zmax + 250,  
              xc ,  yc,  zc,
              0.0, 1.0, 0.0]
plot.camera = cameraMatrix_

Hi @RossBencina show probably the best solution plot.camera = [ xcamera, y_camera, z_camera, x_target, y_target, z_target, x_up, y_up, z_up]

camera - camera position in space target - target where camera is pointed in space up - normal vector showing where is direction of up in projected view (control rotation of camera around line camera,target)

@Depth2World did that solve your problem?

any updates?
