Hello all, I have a triangular base pyramid having four points (three for triangular base and one for height). how can I get the inside points of the pyramid ? Thank you .

Your question is not clear. There are an infinity of points inside a pyramid.

Would that not just be the three base points, which you have, and then add the height to the centroid of those points?

If you have the three base points, and the peak of the pyramid, then any other point is just a linear combination of the base points, and then the peak.

We're going round in circles. Your solid (which is a tetrahedron by the way, not a pyramid) is uniquely defined by 4 four points, the ones you start with. This is the "minimum set of points which can represent" it.
As with any geometric shape, there are an infinity of "inside data point". It's of course not possible to return an infinity of points.

For better understanding, this is the situation - blue dots are available points , red are vertices of pyramid (having yellow faces) , now how to get inside points ??
