change radius of THREE.SphereGeometry with slider #41

Open GoogleCodeExporter opened 9 years ago

What steps will reproduce the problem?
1. move Radius slider, nothing happens

What is the expected output? What do you see instead?

Want to use dat-gui sliders to change the radius of the sphere and later also 
other properties such as segments or thetaLength...

Sphere is generated based on variables but I don't know how to update these 
variables?

What version of the product are you using? On what operating system?

http://stemkoski.github.io/Three.js/js/DAT.GUI.min.js / mac os x 10.6.8 / 
safari, chrome

Please provide any additional information below.

Can't figure out how to do it, thanks for your help.

This is more of a threejs issue. The parameters on the sphere geometry do not 
update the geometry when changed. You probably want to replace "radius = value" 
in your onChange fnuction to:
sphere.geometry = new THREE.SphereGeometry (value, segmentsWidth, 
segmentsHeight, phiStart, phiLength, thetaStart, thetaLength );
sphere.geometry.verticesNeedUpdate = true;

Won't it be cheaper to scale the mesh rather than create a new geometry?
