Computer Graphics 2

Assignment 1

This assignment required us to set up the classic ray tracer scene in a graphics API of our choice. We chose to do it in OpenGL within C++. The code was assembled and compiled in linux. You can download the source code and the makefile. You can click on the thumbnail to the right to see a larger image.

The following code describes the location of our camera and the layout of the scene.

void draw() 
{
	// camera coordinates
	gluLookAt(
		0,0,-5, // eye
		0,0,0, // target
		0,1,0 // up axis
	);

	// the plane
	glBegin(GL_QUADS);
		glVertex3f(3,-1,6);
		glVertex3f(3,-1,-3);
		glVertex3f(-1.5,-1,-3);
		glVertex3f(-2,-1,6);
	glEnd();

	// the front sphere
	glTranslatef(0, .25, 0);
	glutSolidSphere (1.0, 64, 64); 

	// the rear sphere
	glTranslatef(1,-.5,.5);
	glutSolidSphere (.75, 64, 64); 
	  
}

And we placed the light accordingly.

GLfloat mat_specular[] = { 1.0, 1.0, 1.0, 1.0 };
GLfloat mat_shininess[] = { 100.0 };
GLfloat light_position[] = { .2, 1.0, 1.0, 0.0 };

glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
glMaterialfv(GL_FRONT, GL_SHININESS, mat_shininess);
glLightfv(GL_LIGHT0, GL_POSITION, light_position);
