Simple Cube Example

[vnarwal95]

Story

As someone new to computer graphics, I want to see an simple example code and its explanation of how I can use OSPRay engine as a high level graphics library to create interactive and photorealistic 3d application. Current examples are somewhat limited, and OSPRayStudio is too complex. It would be nice to look at an example which showcases more basic features than current examples but does not require knowledge of advance concepts/features.

Acceptance Criteria

• User should be able to view a cube and change the view along three axis either by mouse or by keyboard.
• User should be able to change its texture and color using predefined keys.
• User should be able to switch between ambient light, point light and directional light.
• User should be able to change lighting parameters and change direction rotation
• User should be able to switch between renderer
• User should be able to change camera parameters

Definition of Done

• Acceptance Criteria should be met
• Build files should comply with repository standards
• Readme.md to describe features of example
• Description.md to describe code and Computer Graphics concept.
