view#

Purpose#

Sets the position of the observer in workbox units for 3-D plots.

Note

This function is for the deprecated PQG graphics.

Library#

pgraph

Format#

view(x, y, z)#
Parameters:

  • x (scalar) – the X position in workbox units.

  • y (scalar) – the Y position in workbox units.

  • z (scalar) – the Z position in workbox units.

Remarks#

The size of the workbox is set with volume(). The viewer MUST be outside of the workbox. The closer the position of the observer, the more perspective distortion there will be. If \(x = y = z\), the projection will be isometric.

If view() is not called, a default position will be calculated.

Use viewxyz() to locate the observer in plot coordinates.

Examples#

Note

This function is for use with the deprecated PQG graphics.

library pgraph;

// Set observer position in workbox units for a 3-D plot
view(5, 5, 5);    // isometric view
// ... followed by a surface or contour call
