## Activities

Using a CustomShader operator to read an incoming texture:

1. How can we change the input texture?
2. How can we change the world view?
3. How can we swapfrom the output texture the rgba channgels for bgra?

Using the output texture in a point cloud:

1. How can we change the world view?
2. How can we change the particles positions as a group? How can we move each particle independently?
3. How can we change the particle size and color?

Further additions:

* Usage of operator for body tracking and translating particles with nose movement.
