Sample/snippet of how to rotate an image using gu functions?

[Ess]

I'm hoping someone can help me get an image so rotate using gu. Some code snippets or even just the function i'm supposed to use (with parameters, please) would be greatly appreciated.

if you're rendering it vertex by vertex, (TRIANGLE_STRIP/TRIANGLE_FAN etc)

sceGumRotateZ(valueInRads);

is what you need, although if you know about vertices you'd probably know about transformation matrices too.

if you're rendering SPRITES on the other hand, basically, you cant, SPRITEs are always screen aligned.

Although you should be able to rotate the image by rotating the texture coordinates via a texture matrix.

However I haven't tried this.

Rotating texture coordintaes would not give the desired effect...

Edges would be cut off, because the image on the screen is still square at all times.

To make sprites rotate, you need to stop using sprites and start using quads... vertex and matrix time. :)

just rotate image origin (or create your own
mid point ) around the z axis
