Detailed Description

This class provides an implementation for generating topology, point positions and surface normals 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 and GenerateNormals to orient the cone as necessary (e.g., whose height is aligned with 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);
const size_t numNormals =
GeomUtilConeMeshGenerator::ComputeNumNormals(numRadial);
MyPointContainer<GfVec3f> normals(numNormals);
GeomUtilConeMeshGenerator::GenerateNormals(
normals.begin(), numRadial, radius, height);
