Rendering Hardware

What is a API ?

An API is An interface for letting a program communicate with another program. In web terms: An interface for letting web browsers or web servers.

What is a GPU ?

An GPU is an Ground Processing Unit which receives, interprets  telemetry, data from a vechicle.

What is a Shader ?

A computer program used to determine the final surface properties of an object or image. This often includes arbitrarily complex descriptions of light absorption, diffusion, texture mapping, reflection, refraction, shadowing, surface displacement and post-processing effects. In real-time shading languages there are two different applications of shaders: vertex shaders and pixel shaders.

What is a render engine ?

A render engine is a computer program like 3D Max which lets you create objects scenes and such and be able to scale move and render these objects to your desired affect.

Why is Silicon Graphics ( SGI ) considered to be important in the development of hardware renderers ?

SGI known as Silicon Graphics was founded by Jim clark and Abbey Silverstone in 1982, initially as a 3D maker display terminals.

James clark along with Abbey silverstone was the co founder of the ( SGCI`s)

Limitations of 3D

There is is one main limitation to 3D Max and that is the cost it is very expensive and is very hard to get your head round, the latest version of this program cost around $3500. There are also other limitations as files rendered in 3d Max tend to be very large as they are made up of polygons and the number of polygons used are called polly count.

Radiosity and raytracing

Radiosity is the algorithm which is very dependent on light and from which direction the light is hitting the object and them creates a light reflection, radiosity is very prenowned in 3Ds Max and this is the standard lighting within 3D max.

Raytracing is camera dependent and the reflection in 3D max are set by the cameras angle.

 This is an example of direct Illumination as you can see there is a spot light on this image.

 This a Radiosity image radipsity is better quality but takes longer to render.

Rendering Hardware

A key stage during the 3D development in a particular object, you have to render at the end of the object so it is complete.

 

 

 

3D Development Software

• Cinema 3D
• 3D Max
• Maya
• Auto CAD
• Lightwave
• Rhino
• Havok
• Serif Plus-3D Plus
• Mojo world
• Poser

3D Max lets you create rich and complex designs for many uses. Generate realistic characters for a top-selling game. Bring 3D effects to the big screen. Autodesk® 3ds Max® 2008 3D modeling, animation and rendering software helps design visualisation professionals, game developers and visual effects artists maximise their productivity by streamlining the process of working with complex scenes.  The cost of 3D max is around £2,260.00.

         

The above is an Audi R8 which was designed in 3D`s Max.

Maya

Maya 2008 provides new and enhanced tools for both the high-level manipulation and component-level editing of polygon models.  This is an example on the maya layout an this is a pool table which has been created using maya. The cost for the top of the range Maya package is a total of £4,8995.

AutoCAD is a Computer Assisted Design (CAD) software package for 2D and 3D design and drafting, developed and sold by Autodesk. It runs only on Microsoftt operating systems. A version for the Macintosh was released, but was met with limited acceptance and was later dropped. AutoCAD is used to create various architech projects from buildings to bridges etc.

Cartesian Co-ordinate System

What system do 3D software packages use to create the illusion of working in three-dimensional space?

This is a picture of Rene Descartes the man behind it all.

• The system which 3D software packages use to create the illusion of working in three-dimensional space is the Cartesian Co-ordinate System.

 Who created the system used to create the illusion of working in three dimensinal space? 

• The man behind first inventing this system was a French mathematician called Rene Descartes.

 What are the two axis that commonly define the 2-dimensional Cartesian system?

• The axis is commonly known as the X and the Y axis.

The point where XY axes meet is known as the ?

 

• The point where both the axis meets is known as the origin.

What is the importance of the Z axis ?

 

• The Z axis is important because it locates any point in 3D space.

Write the following point using the format ( x, y, z) .

 

59 Units along the negative x- axis

 

100 units along the positive y- axis

 

50 units along the negative z- axis

 

-59, 100, -50

 

What is the purpose of the viewports?

 

The purpose of the viewport on 3D software packages such as 3D Max is that you can look at every face/side of your object so you can see it in great detail so you can check it it all Symmetrical and there is no one point out of place.

What is an orthographic ?
