warp (Image Processing Toolbox User's Guide)

Display an image as a texture-mapped surface

Syntax

warp(X,map)
warp(I,n)
warp(BW)
warp(RGB)
warp(z,...)
warp(x,y,z,...)
h = warp(...)

Description

warp(X,map) displays the indexed image X with colormap map as a texture map on a simple rectangular surface.

warp(I,n) displays the intensity image I with grayscale colormap of length n as a texture map on a simple rectangular surface.

warp(BW) displays the binary image BW as a texture map on a simple rectangular surface.

warp(RGB) displays the RGB image in the array RGB as a texture map on a simple rectangular surface.

warp(z,...) displays the image on the surface z.

warp(x,y,z...) displays the image on the surface (x,y,z).

h = warp(...) returns a handle to a texture-mapped surface.

Class Support

The input image can be of class logical, uint8, uint16, or double.

Remarks

Texture-mapped surfaces are generally rendered more slowly than images.

Example

This example texture maps an image of a test pattern onto a cylinder.

[x,y,z] = cylinder;
I = imread('testpat1.png');
warp(x,y,z,I);
