Questions

Now, there's time for some more questions testing your understanding of the topics we learned in this chapter:

1. Which OpenGL version will be used if your application uses the ANGLE driver? And what is an ICD?
2. Which draw calls of QPainter are safe to use in the critical path?
3. You see the following OpenGL code we used in one of the examples:

glBegin(GL_TRIANGLES);
glColor3f(1.0, 0.0, 0.0);
glVertex3f(-0.5, -0.5, 0);
...

What is your reaction?

4. What is a stencil and when will it be applied in the graphics pipeline?
5. What optimizations are performed by the default QML scene graph?
6. You are a platform vendor and you'd like to take advantage of non-standard hardware features with your QML applications. What can you do?
7. Why would you consider using QGraphicView in a new project?
8. What kinds of shaders are possible with OpenGL?
