Minecraft tips

• set player at the beginning

• clear scene

• slow down

• don’t render all

@choas#Devoxx #IoTMinecraft

What else?

• more sensor data

• button

• from Minecraft to something else

@choas#Devoxx #IoTMinecraft

WHY?

• 3D view

• nice background

• not business style

• (monitoring)

• “mining” your data

• multi player = multi viewer

• more???
