@Override
public void drawParticles(Vec2[] centers, float radius, ParticleColor[] colors, int count) {
GL2 gl = panel.getGL().getGL2();
gl.glPushMatrix();
transformViewport(gl, zero);
float theta = 2 * MathUtils.PI / NUM_CIRCLE_POINTS;
float c = MathUtils.cos(theta);
float s = MathUtils.sin(theta);
float x = radius;
float y = 0;
for (int i = 0; i < count; i++) {
Vec2 center = centers[i];
