Updating the TexturedSphere example to use ArcBall rotation (and retained Shape)

in Share your Work • 10 months ago

The TexturedSphere example has a comment that it could do with ArcBall rotation (else there is reversal of controls) I have today posted a modified example including ArcBall control at open processing. I have also updated the sphere to be a retained shape in anticipation of processing-2.0. Unfortunately this means to view the sketch you will need to download it as openprocessing does not support opengl sketches of any kind!

Just been experimenting with a transparent tint with above sketch:-

// Generic routine to create a textured sphere
PShape texturedSphere(float r, PImage t) {
PShape sphere = createShape(PShape.GROUP);
sphere.enableStyle();
tint(200, 100);

Now you can see the continents from the other side, not perfect but interesting!!!

I have just revised the sketch to use createShape(SPHERE, radius) and sphere.texture(texmap), thus saving many lines of code.....

Thanks for this!

Unfortunately it seems I am unable to see some (retained?) shapes in Processing 2.0a6. Not just with your example, it happens also to some (not all) of the examples that come with Procesing. No error messages, I just get a black screen.

That is kind of worrying, I've seen your GLSL stuff, so I wouldn't have thought it was a hardware issue, perhaps you should file a bug (although it might have already been fixed there have been a lot of changes since 2.0a6, although my sketch was exported from processing-2.0a6).

This problem is still present in 2.0a7 so I filed a bug here.

* EDIT: Problem solved by updated video card drivers! *
