SketchUp is a program for 3D modeling used by architects, game developers, and film producers. SketchUp can be downloaded as free software oe as the Pro version for additional functionality.See: Google SketchUp
Although SketchUp includes good, basic renderings of your models, you can create much more effective presentations by adding a Photo Realistic rendering Add-on Plugin.

A rendered image can incorporate a variety of rendering features. Some of these features are available in SketchUp, using OpenGL, and some are only available with SketchUp Plugins for high end rendering applications.
- Antialiasing — the process of making edge lines look smoother by blending in the colors at the edges.
- Bump Mapping — a method of simulating small-scale bumpiness on surfaces.
- Depth of Field — objects appear blurry or out of focus when too far in front of or behind the object in focus.
- Edge Highlighting — Accentuation edges.
- Fog — how light dims when passing through non-clear atmosphere or air.
- Glow — defining an object which appears to be illuminated by lights, even if it is in a shadow.
- Morphing — "photoshopping" 3D renderings to appear more life-like.
- Motion Blur — objects appear blurry due to high-speed motion, or the motion of the camera.
- Non-Photorealistic Rendering — rendering of scenes in an artistic style, intended to look like a painting or drawing.
- Indirect Light — incorporating additional illumination from lights reflecting from other surfaces.
- Reflection — mirror-like or highly glossy reflection.
- Refraction — bending of light associated with transparency.
- Shading — how the color and brightness of a surface varies with lighting.
- Shadows — the effect of obstructing light.
- Soft Shadows — varying darkness caused by partially obscured light sources.
- Texture Mapping — a method of applying detail to surfaces.
- Translucency — highly scattered transmission of light through solid objects.
- Transparency — sharp transmission of light through solid objects.
