Detailed Description

This class provides an implementation for generating topology and point positions on a cone of a given radius and height.

The cone is made up of circular cross-sections in the XY plane and is centered at the origin. Each cross-section has numRadial segments. The height is aligned with the Z axis, with the base of the object at Z = -h/2 and apex at Z = h/2.

An optional transform may be provided to GeneratePoints to orient the cone as necessary (e.g., whose height is along the Y axis) .

An additional overload of GeneratePoints is provided to specify the sweep angle for the cone about the +Z axis. When the sweep is less than 360 degrees, the generated geometry is not closed.

Usage:

const size_t numRadial = 8;
const size_t numPoints =
    GeomUtilConeMeshGenerator::ComputeNumPoints(numRadial);
const float radius = 1, height = 2;

MyPointContainer<GfVec3f> points(numPoints);

GeomUtilConeMeshGenerator::GeneratePoints(
    points.begin(), numRadial, radius, height);
