3D Visualization Quick Start

Get started with 3D visualization in XDL.

For the complete guide, see QUICKSTART_VIZ3D.

Surface Plots 

; Create 3D surface
x = findgen(50)
y = findgen(50)
z = sin(sqrt((x-25)^2 + (y-25)^2) / 5)

; Display surface
surface, z

3D Scatter Plots 

; 3D scatter plot
x = randomn(100)
y = randomn(100)
z = randomn(100)

plot3d, x, y, z, psym=3

Wireframe Plots 

; Wireframe surface
x = findgen(30)
y = findgen(30)
z = x # y

wireframe, z

Mesh Plots 

; Mesh plot with color
mesh, z, color_table='rainbow'

Isosurfaces 

; 3D isosurface
data = make_volume(50, 50, 50)
isosurface, data, threshold=0.5

Interactive Viewing

XDL provides interactive 3D viewing:

  • Browser Mode - WebGL rendering in browser
  • Desktop Mode - Native OpenGL rendering
  • Three.js Mode - Advanced web rendering
# Launch browser viewer
xdl-viz3d-browser script.xdl

# Launch desktop viewer
xdl-desktop-viewer script.xdl

Animation 

; Animated surface
for t = 0, 100 do begin
  z = sin(sqrt((x-25)^2 + (y-25)^2) / 5 + t/10.0)
  surface, z
  wait, 0.05
endfor
