Detailed Description

This class provides an implementation for generating topology and point positions on a capsule.

The simplest form takes a radius and height and is a cylinder capped by two hemispheres that is centered at the origin. The generated capsule is made up of circular cross-sections in the XY plane. Each cross-section has numRadial segments. Successive cross-sections for each of the hemispheres are generated at numCapAxial locations along the Z and -Z axes respectively. The height is aligned with the Z axis and represents the height of just the cylindrical portion.

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

An additional overload of GeneratePoints is provided to specify different radii and heights for the bottom and top caps, as well as the sweep angle for the capsule about the +Z axis. When the sweep is less than 360 degrees, the generated geometry is not closed.

Usage:

const size_t numRadial = 4, numCapAxial = 4;
const size_t numPoints =
GeomUtilCapsuleMeshGenerator::ComputeNumPoints(numRadial, numCapAxial);
const float radius = 1, height = 2;
MyPointContainer<GfVec3f> points(numPoints);
GeomUtilCapsuleMeshGenerator::GeneratePoints(
points.begin(), numRadial, numCapAxial, radius, height);
