Point Clouds

[artzor]

Hi Guys,

Was playing around with all the different point cloud vops and besides not understanding how they work i'm trying to figure out what result you could actually achieve?

Anyone got some cool shaders or examples of what using point clouds can do?

Here are some examples that should give you ideas:

Not in shaders, but cool stuff:

This one is inside the shader to write out the pointcloud.

I'm planning on making some tutorials about them as they are so useful and fast.

There are some examples of pointclouds on the exchange as well:

ah great, thanks peter

so, to be more specific. in a vop vex surface shader, can i get the colours from a point cloud and plug it into say, a lambert?

tried using pcopen, the pcfilter but it doesn't seem to be working...

ooh, nevermind, figured out the above example

just transform global P to texture space and sample that, picks up attributes from the point cloud just fine
