Introduction

• Introduction
• I am planning to make a 3d ball game in which
  there is a room which has a bouncing ball and a
  striker controlled by keyboard which is used
  prevent the ball from hitting the ground. The
  image on the previous slide gives a basic view
  model.

Objectives

• Chapter 2
• Use vertex arrays and buffer objects to store and
  access geometric data with fewer function calls.
• Chapter 3
• For specifying the position of the models in the
  scene and choosing a vantage point from which to
  view the scene besides using the default
  positioning and vantage point.
• View a geometric model in any orientation by
  transforming it in three-dimensional space.
• transformation for viewing and project the model
  onto the screen.
• 3. Chapter 4
• Use smooth shading to draw a single polygon with
  more than one color.
• 4. Chapter 5
• Render illuminated objects by defining the
  desired light sources and lighting model.
• 5. Chapter 6
• Blending - Blend colors to achieve such effects
  as making objects appear translucent.
• 6. Chapter 7
• Understand how display lists can be used along
  with commands in immediate mode to organize your
  data and improve performance.
• 7. Chapter 8
• Position and draw bitmapped data.
• Read pixel data (bitmaps and images) from the
  frame-buffer into processor memory and from
  memory into the frame-buffer.
• 8. Chapter 9
• Understand what texture mapping can add to your
  scene.

Objectives - Implementation

• Use vertex arrays and buffer objects to store and
  access geometric data with fewer function calls.
  Chapter 3 - 6 objectives.
• vertex arrays lets you access a set of vertices
  and data by index.
• Vertex arrays were intended to let the programmer
  to specify blocks of dynamic geometry data with
  as few function calls as possible.
• View a geometric model in any orientation by
• transforming it in three-dimensional space.
• transformation for viewing and project the model
  onto the screen.
• gluLookAt(x, y, z, lx, ly, lz,0.0f,1.0f,0.0f)

Objectives Contd.

• Use smooth shading to draw a single polygon with
  more than one color.
• Render illuminated objects by defining the
  desired light sources and lighting model
• Different types of light
• GLfloat LightAmbient 0.5f, 0.5f, 0.5f, 1.0f
  // Ambient Light Values ( NEW )
• GLfloat LightDiffuse 1.0f, 1.0f, 1.0f, 1.0f
  // Diffuse Light Values ( NEW )
• Positioning the light source
• GLfloat LightPosition 0.0f, 0.0f, 2.0f,
  1.0f // Light Position ( NEW )
• Setting up the light
• glLightfv(GL_LIGHT1, GL_AMBIENT, LightAmbient)
  // Setup The Ambient Light
• glLightfv(GL_LIGHT1, GL_DIFFUSE, LightDiffuse)
  // Setup The Diffuse Light
• glLightfv(GL_LIGHT1, GL_POSITION,LightPosition)
  // Position The Light
• glEnable(GL_LIGHT1) // Enable Light One
• Blending - Blend colors to achieve such effects
  as making objects appear translucent
• We enable blending just like everything else.
  Then we set the equation, and turn off depth
  buffer writing when drawing transparent objects,
  since we still want objects behind the
  translucent shapes to be drawn.

Objectives Contd.

• Understand how display lists can be used along
  with commands in immediate mode to organize your
  data and improve performance
• Creating display lists.
• GLuint snowManDL
• // Create the id for the list
• snowManDL glGenLists(1)
• // start list
• glNewList(snowManDL,GL_COMPILE)
• // call the function that contains
• // the rendering commands
• glBegin(GL_LINES)
• .
• .
• glEnd()
• // endList
• glEndList()
• RENDERING
• glCallList(snowman_display_list)

8
Objectives Contd.

• Position and draw bitmapped data.
• Read pixel data (bitmaps and images) from the
  frame-buffer into processor memory and from
  memory into the frame-buffer
• Understand what texture mapping can add to your
  scene
• Control how a texture image is filtered as it's
  applied to a fragment.
• Supply texture coordinates to indicate how the
  texture image shouldbe aligned with the objects
  in your scene.
• Understand what buffers make up the frame-buffer
  and how they're used
• Clear selected buffers and enable them for
  writing.
