Extends

This class extends others, you can call their methods on an instance of ofSpherePrimitive too:

• of3dPrimitive

The ofSpherePrimitive allows you to create an UV sphere, which is a sphere based on UV slices rather than faces like the ofIcoSpherePrimitive. Note this:

On the left is a UV sphere and on the right is an ICO sphere.

Like all primitives it allows you to set the size (radius), draw it, set positions, etc, as a simple example:

void setup()
{

    sphere.setRadius( width );
}

void draw()
{

    sphere.setPosition(ofGetWidth()*.2, ofGetHeight()*.75, 0);
    sphere.rotate(spinX, 1.0, 0.0, 0.0);
    sphere.rotate(spinY, 0, 1.0, 0.0);

    // get all the faces from the icoSphere, handy when you want to copy
    // individual vertices or tweak them a little ;)
    vector<ofMeshFace> triangles = sphere.getMesh().getUniqueFaces();

    // now draw
    sphere.draw();
}

To draw a texture over any primitive, simply bind the ofTexture instance and then draw your primitive:

texture.getTextureReference().bind();
// now draw
sphere.draw();

The sphere can look a little weird if you don't do ofEnabledDepthTesting() and ofDisableAlphaBlending().
