EleRender™ software renders a surface on a display or printer. It can superimpose curves on the surface. In particular, it plots geodesics. EleRender can shade a surface proportional to a scalar field. For example, in an engineering problem, shading can represent temperature.

EleRender capabilities include:

  • Depth sorting accurately renders self-intersecting surfaces.

EleRender user-controlled capabilities include:

  • View point (camera position)
  • View plane (zoom)
  • Aim point
  • Projective transformation
  • Hidden surface removal
  • Light position
  • Ambient-Diffuse-Specular lighting
  • Phong reflective highlighting

Also, EleRender offers the following user-controlled options:

  • Superimposed curve plotting
  • Curve discretation marker
  • Parametric curves
  • Scalar field shading

The unified manifold and geodesic dialog box allows the user to set many graph properties.

EleRender is distributed with Elements™ Engineering-Scientific Workspace. However, it is a software component that can be embedded in any ActiveX document.
