Introduction to OpenGL ES - In practice

1. Start Carbie C/C++
2. Create new Symbian OS project
3. Click on the button "Next", type the project name "openGLEStest" and then press button "Finish"
4. Initiate the OpenGL ES (See part 1 for more detail)
5. Implement the initial code
6. Draw the scene
7. Clean up resource
8. Run the project

Create new Symbian OS project

Project OpenGLES test

Initiate the OpenGL ES (See part for more detail)

Open file openglestestAppView.h, add a function to initiate the OpenGL ES. And add some variables necessary for initiation.

Implement the initial code

Open file openglestestAppView.cpp, add a function void CopenglestestAppView::initGL().

Draw the scene

Open file openglestestAppView.h, add a draw function and a callback function to draw the scene.

Then open the file openglestestAppView.cpp to implement the function drawScence() and DrawCallBack( TAny* aInstance ).

Open the function void CopenglestestAppView::SizeChanged() and void CopenglestestAppView::Draw(const TRect& /*aRect*/) const, comment out the draw code.

Open the function ConstructL(const TRect& aRect) and add some initial code (set the window to full screen, ...)

Clean up resource

Open the destructor function ~CopenglestestAppView() and add some code to free the resource has been used.

Run the project
