Looks nice, I'd test it but I'm on my crappy computer.

@DragonFly

Hmm, let me guess. 6 cameras pointing in the +ve/-ve X,Y & Z directions. They are placed where the spheres are and cube mapping is used to map the images from the cameras onto the spheres.

i think he has 9 cameras, 8 are inside the spheres, pointing toward the camera and then as each image is grabbed from each camera it is pasted onto the sphere and the sphere is pointed at the camera

Does this use DarkBasic Pro's Reflection Shader? If not, than that must be a waste of cameras!

As myself and Indi discovered, camera's are actually faster then the reflection shader but are less accurate (ie, they don't simulate reflections like the real world would). I'm surprised this one runs so fast, but I bet as soon as you started putting more objects into the scene it will run very slow.

The demo is using 6 cameras for make the images for cubemapping. That method runs much faster than reflection shading or 48 real cameras. If you use 2 cameras then the fps will be halved. This version isnt updating all cameras every loop so it saves many fps.

here is a version with real cameras:


and the same with faked cameras:


that sippet was posted by kulle in the german forum.
