Unity
4. Unity
• Cross-platform game creation system devel
oped by Unity Technologies,
– A game engine
– An integrated development environment (IDE).
• Used for developing video games
– web sites, desktop platforms, consoles, and mo
bile devices.
• Unity Pro is available for a fee
• Unity Free has no fee
5. Platforms

9. Graphics
• Meshes
• Textures
• Materials
• Cameras
• Lights
• Skyboxes
• Water effects
10. Lighting
The simulation of light in computer graphics.
11. Texture
• Texture mapping is a method for adding d
etail, surface texture (a bitmap or raster im
age), or color to a computer-generated gra
phic or 3D model.
12. Texture
• Normal map (or "Dot3 bump mapping“) is a techn
ique used for faking the lighting of bumps and de
nts

• blooming
17. Skyboxes
• A skybox is a method of creating backgrounds to make
a computer and video games level look bigger than it rea
lly is. When a skybox is used, the level is enclosed in a c

A skydome employs the same concept
but uses either a sphere or a
hemisphere instead of a cube.

in the graphics pipeline?
20. Stages of the graphics pipeline
