WebGL rotating F: Difference between revisions

=={{header|Julia}}==

Makie can use OpenGL as a backend for plotting (GLMakie). The code plots an 'F' as three rectangular solid-shaped scatter plots with overlapping markers, then rotates the resulting graph.

using GeometryBasics: Rect3f

using GLMakie

sleep(0.25)

end

You can run this online [http://phix.x10.mx/p2js/HelloF.htm here] (which gives me around 10% CPU load, with space toggling the timer for no extra load). No teapot, sorry.

=={{header|Wren}}==

As with any Open GL aplication, the Wren code needs to be embedded in a host application which can communicate directly with the relevant libraries and which I've written here in C.

import "./math" for Math

Glut.setOption(GLUT_ACTION_ON_WINDOW_CLOSE, GLUT_ACTION_GLUTMAINLOOP_RETURNS)

init.call()

We now embed the above code in the following C program, compile and run.

#include <stdlib.h>

free(script);

return 0;
