There's many ways to create a point or points. Yes particles are infinitely small, unless you have scalePP, and a dimensionless point can't possibly have colour, unless of course you've defined rgbPP, etc. If you have it will use that as a velocity vector, for colour etc.Īgain relating back to maya, the particle comparison holds true. If you have a attribute, it uses that as a radius instead. For Houdini and Mantra, they treat points as spheres with a radius of 0.1. In a mathematically pure sense of a point, this makes no sense, they're infinitely small, invisible things. The answer is that while a Houdini point derives from a mathematical point, we're not mathematicians damnit, we can do whatever the hell we want! For example, you have points representing a spray of water, and you want to render them. How can a dimensionless point have a normal? Or area? Maya particles can store colour as rgbPP, speed, velocity etc, a houdini point can also store colour, speed, velocity, as attributes, and even some attributes that don't make sense for a particle, like normal and scale. At it's most basic, a point will store its position you're coming from other 3d packages, a point is equivalent to a particle a standalone position in space.
Nearly everything in Houdini directly assumes you're working with points, just think in those terms, everything should work.Ī point in Houdini is close to the mathematical definition of a point it's a location in space, with no associated area or dimension or connectivity. Short Answer - don't worry about it, just use points 6 Visualising points and verts and prims.1 Short Answer - don't worry about it, just use points.You may have to select a menu option or click a button.
