OpenGL/Utah teapot: Difference between revisions

 

This implementation sticks to the task requirements and only shows the teapot, it's rotating, so you can enjoy it's magnificence from all possible viewpoints and perspectives.

Although there are a number of third party Go bindings for OpenGL, the following uses 'cgo' to interface directly with the C libraries.

 

/*

C.glutMainLoop()

C.free(unsafe.Pointer(tlc))

Direct translation from C.

Makie implements OpenGL shading graphics as part of its plotting functionality. The files are from the University of Utah site.

 

if stat("newell_teaset/teapot.obj").size == 0

rotate!(scene, Quaternion(0.6, 0.2, 0.2, 4.0))

display(scene)

</pre>

You then need to compile the following Kotlin program, linking against opengl.klib, and run the resulting .kexe file to view the rotating teapot.

 

import kotlinx.cinterop.*

glutIdleFunc(staticCFunction(::onIdle))

glutMainLoop()

To run this, you will need the freeglut package from [http://phix.x10.mx/pmwiki/pmwiki.php?n=Main.Freeglut-TheFreeOpenglUtilityToolkit PCAN]

As it's not currently possible for Wren-cli to access OpenGL directly, we embed a Wren script in a C application to complete this task. See the [[OpenGL#Wren]] task for some of the issues involved here.

 

var Rot = 0

Glut.displayFunc("GLCallbacks", "display()")

Glut.idleFunc("GLCallbacks", "onIdle()")

<br>

We now embed this Wren script in the following C program, compile and run it.

#include <stdio.h>

#include <string.h>

free(script);

return 0;
