sphereDetail() / Reference / Processing.org

Name

sphereDetail()

Description

Controls the detail used to render a sphere by adjusting the number of vertices of the sphere mesh. The default resolution is 30, which creates a fairly detailed sphere definition with vertices every 360/30 = 12 degrees. If you're going to render a great number of spheres per frame, it is advised to reduce the level of detail using this function. The setting stays active until sphereDetail() is called again with a new parameter and so should not be called prior to every sphere() statement, unless you wish to render spheres with different settings, e.g. using less detail for smaller spheres or ones further away from the camera. To control the detail of the horizontal and vertical resolution independently, use the version of the functions with two parameters.

Examples

void setup() {
  size(100, 100, P3D); 
}

void draw() {
  background(200);
  stroke(255, 50);
  translate(50, 50, 0);
  rotateX(mouseY * 0.05);
  rotateY(mouseX * 0.05);
  fill(mouseX * 2, 0, 160);
  sphereDetail(mouseX / 4);
  sphere(40);
}

Syntax

Parameters

res(int)number of segments (minimum 3) used per full circle revolution
ures(int)number of segments used longitudinally per full circle revolution
vres(int)number of segments used latitudinally from top to bottom

Return

void
