MATLAB: Is the WATERFALL command so slow in MATLAB 7 (R14)

MATLABopenglpaintersrendererwaterfall

Using WATERFALL in MATLAB 7 (R14) takes much more time than in previous releases.

Best Answer

This behavior is due to the way in which WATERFALL uses the renderers.

To work around this, set the renderer to OPENGL:

figure(1)
set(gcf,'renderer','opengl');
waterfall(x,y,z)

MATLAB: Is the WARP command unable to display the expected texture mapped surface on Windows when using MATLAB 7.0 (R14)

This limitation is the result of a renderer issue on the Windows platform .The WARP command generates this result when the renderer is set to "Painters".

To work around this issue, set the renderer to ''OpenGL'' or "Zbuffer". The example below shows how to set the renderer to OpenGL:

close all 
set(gcf,'Renderer','OpenGL');
[x,y,z] = cylinder;
I = imread('testpat1.png'); 
warp(x,y,z,I);
